Summary: CMedia 8768 Support
Description:
I've recently built a new computer with an on-board CMedia 8768 chip. This
chip is not listed as one of the supported CMedia chips (8738, etc.),
although I suspect that is because it is so new. Just wanted to let you
guys know it apparently doesn't work with the standard cmipci driver (at
least I think I'm doing everthing correctly -- I have a decent amount of
Linux experience but I'm no guru). Here is what I see though:
The card is recognized in /proc/asound as a CMedia 8738M6. However, if I
use a mixer like amixer or gnome-alsamixer none of the mixer settings I
change will take effect (and I am running these as root).
Any advice or comments would be appreciated. I'd be happy to help if you
think there is a possible fix.

----------------------------------------------------------------------
robg - 07-27-2004 05:26 CEST
----------------------------------------------------------------------
Is there any progress on a driver for this chip?
It is used on the Soltek EQ3801 amd64 computer and a lot of people in
forums on other websites are interested in sound support.
I have the same problems as listed by drbobguy. I tested it under 64bit
kernel 2.6.7 I believe he did as well. I can setup a 32bit kernel and
retest if you fell its useful.
----------------------------------------------------------------------

Any datasheet available?
I don't know of...
----------------------------------------------------------------------
drbobguy - 07-31-2004 02:46 CEST
----------------------------------------------------------------------
I found this file off the CMedia website (I've attached it here):
http://www.cmedia.com.tw/doc/CMI8768%20Datasheet%20Rev%200.9.pdf
----------------------------------------------------------------------
robg - 07-31-2004 06:10 CEST
----------------------------------------------------------------------
The file from cmedia website does not contain any info for programming the
chip unfortunately. I have sent an email to cmedia requesting full
information. Will advise when I get a response.
Since the chip gives an ID of CMI8738-MC6 it may be very close to the
existing driver.
In the interim, is there any more information we can provide from /proc
that is useful?
----------------------------------------------------------------------
robg - 10-08-2004 05:17 CEST
----------------------------------------------------------------------
Finally get some feedback from Cmedia. Following is copy of email
exchanges. I will attach documentation also received.

Dear Rob,
I'm sorry I missed your previous mail. I enclosed 8768 datasheet, register
spec and programming guide to you. 8768 is basically modified from 8738
and hence the 8738 programming guide is applicable. Hope them helpful.
Shall you have any specific question or further need, you can tell us
then.
BTW, our Linux driver developer is Chen-Li Tien (in CC list) and he is
also working on this. You can have a talk if you would like.
Regards,
Jason

Dear Mr Liang,
I am working with the ALSA linux sound media team to implement a driver
for the new 8768 soundchip. This is currently used in the Soltek EQ3801
computer and there is a lot of interest in the Linux community to obtain
a working driver.
Since the technical details and an open source driver were available for
the 8738, I was hoping that the same level of information would be
published for the 8768 as well.
I am willing to work on the driver development if sufficient technical
documentation is provided, assuming a driver has not been prepared
already.
I have tried contacting the support group at Cmedia
(support@cmedia.com.tw ) several times but have not received any reply.
Can you assist in obtaining the information required or provide the name
of a contact person who could help?
Thank-you for your time.
Regards,
Rob Gordon

According to the datasheet, CM8768 seems almost backward compatible
with CM8738 (6ch).
What did you mean in the original post, "none of the mixer settings I
change will take effect"? Isn't the mixer value changed at all, or
you get only the silent output, although the playback looks as if
working?

Summary: CMedia 8768 Support
Description:
I've recently built a new computer with an on-board CMedia 8768 chip. This
chip is not listed as one of the supported CMedia chips (8738, etc.),
although I suspect that is because it is so new. Just wanted to let you
guys know it apparently doesn't work with the standard cmipci driver (at
least I think I'm doing everthing correctly -- I have a decent amount of
Linux experience but I'm no guru). Here is what I see though:
The card is recognized in /proc/asound as a CMedia 8738M6. However, if I
use a mixer like amixer or gnome-alsamixer none of the mixer settings I
change will take effect (and I am running these as root).
Any advice or comments would be appreciated. I'd be happy to help if you
think there is a possible fix.

By the way I'm on an AMD 64 machine if that makes a difference.
----------------------------------------------------------------------
robg - 07-27-2004 05:26 CEST
----------------------------------------------------------------------
Is there any progress on a driver for this chip?
It is used on the Soltek EQ3801 amd64 computer and a lot of people in
forums on other websites are interested in sound support.
I have the same problems as listed by drbobguy. I tested it under 64bit
kernel 2.6.7 I believe he did as well. I can setup a 32bit kernel and
retest if you fell its useful.
----------------------------------------------------------------------
tiwai - 07-30-2004 16:56 CEST
----------------------------------------------------------------------
Any datasheet available?
I don't know of...
----------------------------------------------------------------------
drbobguy - 07-31-2004 02:46 CEST
----------------------------------------------------------------------
I found this file off the CMedia website (I've attached it here):
http://www.cmedia.com.tw/doc/CMI8768%20Datasheet%20Rev%200.9.pdf
----------------------------------------------------------------------
robg - 07-31-2004 06:10 CEST
----------------------------------------------------------------------
The file from cmedia website does not contain any info for programming the
chip unfortunately. I have sent an email to cmedia requesting full
information. Will advise when I get a response.
Since the chip gives an ID of CMI8738-MC6 it may be very close to the
existing driver.
In the interim, is there any more information we can provide from /proc
that is useful?
----------------------------------------------------------------------
robg - 10-08-2004 05:17 CEST
----------------------------------------------------------------------
Finally get some feedback from Cmedia. Following is copy of email
exchanges. I will attach documentation also received.

Dear Rob,
I'm sorry I missed your previous mail. I enclosed 8768 datasheet, register
spec and programming guide to you. 8768 is basically modified from 8738
and hence the 8738 programming guide is applicable. Hope them helpful.
Shall you have any specific question or further need, you can tell us
then.
BTW, our Linux driver developer is Chen-Li Tien (in CC list) and he is
also working on this. You can have a talk if you would like.

Dear Mr Liang,
I am working with the ALSA linux sound media team to implement a driver
for the new 8768 soundchip. This is currently used in the Soltek EQ3801
computer and there is a lot of interest in the Linux community to obtain
a working driver.
Since the technical details and an open source driver were available for
the 8738, I was hoping that the same level of information would be
published for the 8768 as well.
I am willing to work on the driver development if sufficient technical
documentation is provided, assuming a driver has not been prepared
already.
I have tried contacting the support group at Cmedia
(support@cmedia.com.tw ) several times but have not received any reply.
Can you assist in obtaining the information required or provide the name
of a contact person who could help?
Thank-you for your time.

When I run a command like "amixer set Master 10" I get what looks like
proper output. The adjustments don't seem to stick though. Volume for
Master/PCM etc are always listed at 100% in alsamixer and even after
issuing the unmute command for PCM it is always listed as muted.
But if I try to use the ncurses program alsamixer none of the settings are
adjustable. Likewise if I try to use beep-media-player it says it "can't
open audio."
So yeah, I can't get any sound out of it and most audio programs either
give an error about not being able to access the device or just sit there
and do nothing (like aplay).
If you need any more information let me know, I'll try to help as best I
can. Thank you!

A good news! It will help for debugging. Thanks.

According to the datasheet, CM8768 seems almost backward compatible
with CM8738 (6ch).
What did you mean in the original post, "none of the mixer settings I
change will take effect"? Isn't the mixer value changed at all, or
you get only the silent output, although the playback looks as if
working?
----------------------------------------------------------------------
tiwai - 10-08-2004 15:36 CEST
----------------------------------------------------------------------
Also, attach /etc/asound.state and /proc/asound/card0/cmipci for
debugging.
----------------------------------------------------------------------

When I run a command like "amixer set Master 10" I get what looks like
proper output. The adjustments don't seem to stick though. Volume for
Master/PCM etc are always listed at 100% in alsamixer and even after
issuing the unmute command for PCM it is always listed as muted.
But if I try to use the ncurses program alsamixer none of the settings are
adjustable. Likewise if I try to use beep-media-player it says it "can't
open audio."
So yeah, I can't get any sound out of it and most audio programs either
give an error about not being able to access the device or just sit there
and do nothing (like aplay).
If you need any more information let me know, I'll try to help as best I
can. Thank you!

I get the same problems as patrick for amixer and alsamixer operation. To
verify proper alsa setup, I disabled the 8768 in bios and installed a SB
es1371 and all controls and audio output works.
I use AMD 64-bit kernel 2.6.8-rc2.
I will attach /etc/asound.state and /proc/asound/card0/cmipci as
suggested.

Summary: CMedia 8768 Support
Description:
I've recently built a new computer with an on-board CMedia 8768 chip. This
chip is not listed as one of the supported CMedia chips (8738, etc.),
although I suspect that is because it is so new. Just wanted to let you
guys know it apparently doesn't work with the standard cmipci driver (at
least I think I'm doing everthing correctly -- I have a decent amount of
Linux experience but I'm no guru). Here is what I see though:
The card is recognized in /proc/asound as a CMedia 8738M6. However, if I
use a mixer like amixer or gnome-alsamixer none of the mixer settings I
change will take effect (and I am running these as root).
Any advice or comments would be appreciated. I'd be happy to help if you
think there is a possible fix.
======================================================================

drbobguy - 07-07-2004 05:03 CEST

By the way I'm on an AMD 64 machine if that makes a difference.
----------------------------------------------------------------------
robg - 07-27-2004 05:26 CEST
----------------------------------------------------------------------
Is there any progress on a driver for this chip?
It is used on the Soltek EQ3801 amd64 computer and a lot of people in
forums on other websites are interested in sound support.
I have the same problems as listed by drbobguy. I tested it under 64bit
kernel 2.6.7 I believe he did as well. I can setup a 32bit kernel and
retest if you fell its useful.
----------------------------------------------------------------------
tiwai - 07-30-2004 16:56 CEST
----------------------------------------------------------------------
Any datasheet available?
I don't know of...
----------------------------------------------------------------------
drbobguy - 07-31-2004 02:46 CEST
----------------------------------------------------------------------
I found this file off the CMedia website (I've attached it here):
http://www.cmedia.com.tw/doc/CMI8768%20Datasheet%20Rev%200.9.pdf
----------------------------------------------------------------------
robg - 07-31-2004 06:10 CEST
----------------------------------------------------------------------
The file from cmedia website does not contain any info for programming the
chip unfortunately. I have sent an email to cmedia requesting full
information. Will advise when I get a response.
Since the chip gives an ID of CMI8738-MC6 it may be very close to the
existing driver.
In the interim, is there any more information we can provide from /proc
that is useful?
----------------------------------------------------------------------
robg - 10-08-2004 05:17 CEST
----------------------------------------------------------------------
Finally get some feedback from Cmedia. Following is copy of email
exchanges. I will attach documentation also received.

Dear Rob,
I'm sorry I missed your previous mail. I enclosed 8768 datasheet, register
spec and programming guide to you. 8768 is basically modified from 8738
and hence the 8738 programming guide is applicable. Hope them helpful.
Shall you have any specific question or further need, you can tell us
then.
BTW, our Linux driver developer is Chen-Li Tien (in CC list) and he is
also working on this. You can have a talk if you would like.

Dear Mr Liang,
I am working with the ALSA linux sound media team to implement a driver
for the new 8768 soundchip. This is currently used in the Soltek EQ3801
computer and there is a lot of interest in the Linux community to obtain
a working driver.
Since the technical details and an open source driver were available for
the 8738, I was hoping that the same level of information would be
published for the 8768 as well.
I am willing to work on the driver development if sufficient technical
documentation is provided, assuming a driver has not been prepared
already.
I have tried contacting the support group at Cmedia
(support@cmedia.com.tw ) several times but have not received any reply.
Can you assist in obtaining the information required or provide the name
of a contact person who could help?

Summary: CMedia 8768 Support
Description:
I've recently built a new computer with an on-board CMedia 8768 chip. This
chip is not listed as one of the supported CMedia chips (8738, etc.),
although I suspect that is because it is so new. Just wanted to let you
guys know it apparently doesn't work with the standard cmipci driver (at
least I think I'm doing everthing correctly -- I have a decent amount of
Linux experience but I'm no guru). Here is what I see though:
The card is recognized in /proc/asound as a CMedia 8738M6. However, if I
use a mixer like amixer or gnome-alsamixer none of the mixer settings I
change will take effect (and I am running these as root).
Any advice or comments would be appreciated. I'd be happy to help if you
think there is a possible fix.

By the way I'm on an AMD 64 machine if that makes a difference.
----------------------------------------------------------------------
robg - 07-27-2004 05:26 CEST
----------------------------------------------------------------------
Is there any progress on a driver for this chip?
It is used on the Soltek EQ3801 amd64 computer and a lot of people in
forums on other websites are interested in sound support.
I have the same problems as listed by drbobguy. I tested it under 64bit
kernel 2.6.7 I believe he did as well. I can setup a 32bit kernel and
retest if you fell its useful.
----------------------------------------------------------------------
tiwai - 07-30-2004 16:56 CEST
----------------------------------------------------------------------
Any datasheet available?
I don't know of...
----------------------------------------------------------------------
drbobguy - 07-31-2004 02:46 CEST
----------------------------------------------------------------------
I found this file off the CMedia website (I've attached it here):
http://www.cmedia.com.tw/doc/CMI8768%20Datasheet%20Rev%200.9.pdf
----------------------------------------------------------------------
robg - 07-31-2004 06:10 CEST
----------------------------------------------------------------------
The file from cmedia website does not contain any info for programming the
chip unfortunately. I have sent an email to cmedia requesting full
information. Will advise when I get a response.
Since the chip gives an ID of CMI8738-MC6 it may be very close to the
existing driver.
In the interim, is there any more information we can provide from /proc
that is useful?
----------------------------------------------------------------------
robg - 10-08-2004 05:17 CEST
----------------------------------------------------------------------
Finally get some feedback from Cmedia. Following is copy of email
exchanges. I will attach documentation also received.

Dear Rob,
I'm sorry I missed your previous mail. I enclosed 8768 datasheet, register
spec and programming guide to you. 8768 is basically modified from 8738
and hence the 8738 programming guide is applicable. Hope them helpful.
Shall you have any specific question or further need, you can tell us
then.
BTW, our Linux driver developer is Chen-Li Tien (in CC list) and he is
also working on this. You can have a talk if you would like.

I am still looking for information on programming the 8768 soundchip.
Can you provide a contact so I can can pursue this information.

Dear Mr Liang,
I am working with the ALSA linux sound media team to implement a driver
for the new 8768 soundchip. This is currently used in the Soltek EQ3801
computer and there is a lot of interest in the Linux community to obtain
a working driver.
Since the technical details and an open source driver were available for
the 8738, I was hoping that the same level of information would be
published for the 8768 as well.
I am willing to work on the driver development if sufficient technical
documentation is provided, assuming a driver has not been prepared
already.
I have tried contacting the support group at Cmedia
(support@cmedia.com.tw ) several times but have not received any reply.
Can you assist in obtaining the information required or provide the name
of a contact person who could help?
Thank-you for your time.
Regards,
Rob Gordon

A good news! It will help for debugging. Thanks.
----------------------------------------------------------------------
tiwai - 10-08-2004 15:26 CEST
----------------------------------------------------------------------
According to the datasheet, CM8768 seems almost backward compatible
with CM8738 (6ch).
What did you mean in the original post, "none of the mixer settings I
change will take effect"? Isn't the mixer value changed at all, or
you get only the silent output, although the playback looks as if
working?
----------------------------------------------------------------------
tiwai - 10-08-2004 15:36 CEST
----------------------------------------------------------------------
Also, attach /etc/asound.state and /proc/asound/card0/cmipci for
debugging.
----------------------------------------------------------------------
patrick - 10-09-2004 09:30 CEST
----------------------------------------------------------------------
When I run a command like "amixer set Master 10" I get what looks like
proper output. The adjustments don't seem to stick though. Volume for
Master/PCM etc are always listed at 100% in alsamixer and even after
issuing the unmute command for PCM it is always listed as muted.
But if I try to use the ncurses program alsamixer none of the settings are
adjustable. Likewise if I try to use beep-media-player it says it "can't
open audio."
So yeah, I can't get any sound out of it and most audio programs either
give an error about not being able to access the device or just sit there
and do nothing (like aplay).
If you need any more information let me know, I'll try to help as best I
can. Thank you!

I get the same problems as patrick for amixer and alsamixer operation. To
verify proper alsa setup, I disabled the 8768 in bios and installed a SB
es1371 and all controls and audio output works.
I use AMD 64-bit kernel 2.6.8-rc2.
I will attach /etc/asound.state and /proc/asound/card0/cmipci as
suggested.
----------------------------------------------------------------------
robg - 10-10-2004 04:57 CEST
----------------------------------------------------------------------
I checked and my /etc/asound.state and /proc/asound/card0/cmipci were
identical to those uploaded by patrick so I didn't upload them.
Using aplay I get the following error:
#aplay /usr/lib/mozilla/res/samples/test.wav
Playing WAVE '/usr/lib/mozilla/res/samples/test.wav' : Unsigned 8 bit,

----------------------------------------------------------------------
tiwai - 10-13-2004 16:37 CEST
----------------------------------------------------------------------
The register dump is all ff, that is, the driver is reading wrong I/O
ports.
Can you show the output of "lspci -xvv" ?
----------------------------------------------------------------------
tiwai - 10-13-2004 16:37 CEST
----------------------------------------------------------------------
Also, please use 1.0.7-rc2 for avoid unnecessary differences.

Summary: CMedia 8768 Support
Description:
I've recently built a new computer with an on-board CMedia 8768 chip. This
chip is not listed as one of the supported CMedia chips (8738, etc.),
although I suspect that is because it is so new. Just wanted to let you
guys know it apparently doesn't work with the standard cmipci driver (at
least I think I'm doing everthing correctly -- I have a decent amount of
Linux experience but I'm no guru). Here is what I see though:
The card is recognized in /proc/asound as a CMedia 8738M6. However, if I
use a mixer like amixer or gnome-alsamixer none of the mixer settings I
change will take effect (and I am running these as root).
Any advice or comments would be appreciated. I'd be happy to help if you
think there is a possible fix.

By the way I'm on an AMD 64 machine if that makes a difference.
----------------------------------------------------------------------
robg - 07-27-2004 05:26 CEST
----------------------------------------------------------------------
Is there any progress on a driver for this chip?
It is used on the Soltek EQ3801 amd64 computer and a lot of people in
forums on other websites are interested in sound support.
I have the same problems as listed by drbobguy. I tested it under 64bit
kernel 2.6.7 I believe he did as well. I can setup a 32bit kernel and
retest if you fell its useful.
----------------------------------------------------------------------
tiwai - 07-30-2004 16:56 CEST
----------------------------------------------------------------------

I don't know of...

I found this file off the CMedia website (I've attached it here):

----------------------------------------------------------------------
robg - 07-31-2004 06:10 CEST
----------------------------------------------------------------------
The file from cmedia website does not contain any info for programming the
chip unfortunately. I have sent an email to cmedia requesting full
information. Will advise when I get a response.
Since the chip gives an ID of CMI8738-MC6 it may be very close to the
existing driver.
In the interim, is there any more information we can provide from /proc
that is useful?
----------------------------------------------------------------------
robg - 10-08-2004 05:17 CEST
----------------------------------------------------------------------
Finally get some feedback from Cmedia. Following is copy of email

I gave the patch a try just now and I can't seem to produce any different
results. I only had a moment to poke at it though since I am off to work
now.
Maybe some one else will have more luck with it?
Thank you for doing all of this by the way!

Summary: CMedia 8768 Support
Description:
I've recently built a new computer with an on-board CMedia 8768 chip. This
chip is not listed as one of the supported CMedia chips (8738, etc.),
although I suspect that is because it is so new. Just wanted to let you
guys know it apparently doesn't work with the standard cmipci driver (at
least I think I'm doing everthing correctly -- I have a decent amount of
Linux experience but I'm no guru). Here is what I see though:
The card is recognized in /proc/asound as a CMedia 8738M6. However, if I
use a mixer like amixer or gnome-alsamixer none of the mixer settings I
change will take effect (and I am running these as root).
Any advice or comments would be appreciated. I'd be happy to help if you
think there is a possible fix.

By the way I'm on an AMD 64 machine if that makes a difference.
----------------------------------------------------------------------
robg - 07-27-2004 05:26 CEST
----------------------------------------------------------------------
Is there any progress on a driver for this chip?
It is used on the Soltek EQ3801 amd64 computer and a lot of people in
forums on other websites are interested in sound support.
I have the same problems as listed by drbobguy. I tested it under 64bit
kernel 2.6.7 I believe he did as well. I can setup a 32bit kernel and
retest if you fell its useful.
----------------------------------------------------------------------
tiwai - 07-30-2004 16:56 CEST
----------------------------------------------------------------------
Any datasheet available?
I don't know of...
----------------------------------------------------------------------
drbobguy - 07-31-2004 02:46 CEST
----------------------------------------------------------------------
I found this file off the CMedia website (I've attached it here):
http://www.cmedia.com.tw/doc/CMI8768%20Datasheet%20Rev%200.9.pdf
----------------------------------------------------------------------
robg - 07-31-2004 06:10 CEST
----------------------------------------------------------------------
The file from cmedia website does not contain any info for programming the
chip unfortunately. I have sent an email to cmedia requesting full
information. Will advise when I get a response.
Since the chip gives an ID of CMI8738-MC6 it may be very close to the
existing driver.
In the interim, is there any more information we can provide from /proc
that is useful?
----------------------------------------------------------------------
robg - 10-08-2004 05:17 CEST
----------------------------------------------------------------------
Finally get some feedback from Cmedia. Following is copy of email
exchanges. I will attach documentation also received.

Dear Rob,
I'm sorry I missed your previous mail. I enclosed 8768 datasheet, register
spec and programming guide to you. 8768 is basically modified from 8738
and hence the 8738 programming guide is applicable. Hope them helpful.
Shall you have any specific question or further need, you can tell us
then.
BTW, our Linux driver developer is Chen-Li Tien (in CC list) and he is
also working on this. You can have a talk if you would like.

Dear Mr Liang,
I am working with the ALSA linux sound media team to implement a driver
for the new 8768 soundchip. This is currently used in the Soltek EQ3801
computer and there is a lot of interest in the Linux community to obtain
a working driver.
Since the technical details and an open source driver were available for
the 8738, I was hoping that the same level of information would be
published for the 8768 as well.
I am willing to work on the driver development if sufficient technical
documentation is provided, assuming a driver has not been prepared
already.
I have tried contacting the support group at Cmedia
(support@cmedia.com.tw ) several times but have not received any reply.
Can you assist in obtaining the information required or provide the name
of a contact person who could help?
Thank-you for your time.

A good news! It will help for debugging. Thanks.
----------------------------------------------------------------------
tiwai - 10-08-2004 15:26 CEST
----------------------------------------------------------------------
According to the datasheet, CM8768 seems almost backward compatible
with CM8738 (6ch).
What did you mean in the original post, "none of the mixer settings I
change will take effect"? Isn't the mixer value changed at all, or
you get only the silent output, although the playback looks as if
working?
----------------------------------------------------------------------
tiwai - 10-08-2004 15:36 CEST
----------------------------------------------------------------------
Also, attach /etc/asound.state and /proc/asound/card0/cmipci for
debugging.
----------------------------------------------------------------------
patrick - 10-09-2004 09:30 CEST
----------------------------------------------------------------------
When I run a command like "amixer set Master 10" I get what looks like
proper output. The adjustments don't seem to stick though. Volume for
Master/PCM etc are always listed at 100% in alsamixer and even after
issuing the unmute command for PCM it is always listed as muted.
But if I try to use the ncurses program alsamixer none of the settings are
adjustable. Likewise if I try to use beep-media-player it says it "can't
open audio."
So yeah, I can't get any sound out of it and most audio programs either
give an error about not being able to access the device or just sit there
and do nothing (like aplay).
If you need any more information let me know, I'll try to help as best I
can. Thank you!

I get the same problems as patrick for amixer and alsamixer operation. To
verify proper alsa setup, I disabled the 8768 in bios and installed a SB
es1371 and all controls and audio output works.
I use AMD 64-bit kernel 2.6.8-rc2.
I will attach /etc/asound.state and /proc/asound/card0/cmipci as
suggested.
----------------------------------------------------------------------
robg - 10-10-2004 04:57 CEST
----------------------------------------------------------------------
I checked and my /etc/asound.state and /proc/asound/card0/cmipci were
identical to those uploaded by patrick so I didn't upload them.
Using aplay I get the following error:
#aplay /usr/lib/mozilla/res/samples/test.wav

tiwai - 10-13-2004 16:37 CEST
----------------------------------------------------------------------
The register dump is all ff, that is, the driver is reading wrong I/O
ports.
Can you show the output of "lspci -xvv" ?
----------------------------------------------------------------------
tiwai - 10-13-2004 16:37 CEST
----------------------------------------------------------------------
Also, please use 1.0.7-rc2 for avoid unnecessary differences.

Did you check /proc/asound/card0/cmipci? Now it should address d400.
BTW, do you have a 32bit system on it? It might be a problem of
64bit kernel.

When I run a command like "amixer set Master 10" I get what looks like
proper output. The adjustments don't seem to stick though. Volume for
Master/PCM etc are always listed at 100% in alsamixer and even after
issuing the unmute command for PCM it is always listed as muted.
But if I try to use the ncurses program alsamixer none of the settings are
adjustable. Likewise if I try to use beep-media-player it says it "can't
open audio."
So yeah, I can't get any sound out of it and most audio programs either
give an error about not being able to access the device or just sit there
and do nothing (like aplay).
If you need any more information let me know, I'll try to help as best I
can. Thank you!

I get the same problems as patrick for amixer and alsamixer operation. To
verify proper alsa setup, I disabled the 8768 in bios and installed a SB
es1371 and all controls and audio output works.
I use AMD 64-bit kernel 2.6.8-rc2.
I will attach /etc/asound.state and /proc/asound/card0/cmipci as
suggested.
----------------------------------------------------------------------
robg - 10-10-2004 04:57 CEST
----------------------------------------------------------------------
I checked and my /etc/asound.state and /proc/asound/card0/cmipci were
identical to those uploaded by patrick so I didn't upload them.
Using aplay I get the following error:

The register dump is all ff, that is, the driver is reading wrong I/O
ports.
Can you show the output of "lspci -xvv" ?
----------------------------------------------------------------------

Also, please use 1.0.7-rc2 for avoid unnecessary differences.

Did you check /proc/asound/card0/cmipci? Now it should address d400.
BTW, do you have a 32bit system on it? It might be a problem of
64bit kernel.
----------------------------------------------------------------------

Yes I am using a 64-bit kernel. The motherboard this chip is built on is
an nforce3 250 board so as far as I know they are all 64 bit systems.
Maybe some one else has a 32bit kernel they can test it on but I do not.

Summary: CMedia 8768 Support
Description:
I've recently built a new computer with an on-board CMedia 8768 chip. This
chip is not listed as one of the supported CMedia chips (8738, etc.),
although I suspect that is because it is so new. Just wanted to let you
guys know it apparently doesn't work with the standard cmipci driver (at
least I think I'm doing everthing correctly -- I have a decent amount of
Linux experience but I'm no guru). Here is what I see though:
The card is recognized in /proc/asound as a CMedia 8738M6. However, if I
use a mixer like amixer or gnome-alsamixer none of the mixer settings I
change will take effect (and I am running these as root).
Any advice or comments would be appreciated. I'd be happy to help if you
think there is a possible fix.

By the way I'm on an AMD 64 machine if that makes a difference.
----------------------------------------------------------------------
robg - 07-27-2004 05:26 CEST
----------------------------------------------------------------------
Is there any progress on a driver for this chip?
It is used on the Soltek EQ3801 amd64 computer and a lot of people in
forums on other websites are interested in sound support.
I have the same problems as listed by drbobguy. I tested it under 64bit
kernel 2.6.7 I believe he did as well. I can setup a 32bit kernel and
retest if you fell its useful.
----------------------------------------------------------------------
tiwai - 07-30-2004 16:56 CEST
----------------------------------------------------------------------
Any datasheet available?
I don't know of...
----------------------------------------------------------------------
drbobguy - 07-31-2004 02:46 CEST
----------------------------------------------------------------------
I found this file off the CMedia website (I've attached it here):
http://www.cmedia.com.tw/doc/CMI8768%20Datasheet%20Rev%200.9.pdf
----------------------------------------------------------------------
robg - 07-31-2004 06:10 CEST
----------------------------------------------------------------------
The file from cmedia website does not contain any info for programming the
chip unfortunately. I have sent an email to cmedia requesting full
information. Will advise when I get a response.
Since the chip gives an ID of CMI8738-MC6 it may be very close to the
existing driver.
In the interim, is there any more information we can provide from /proc
that is useful?
----------------------------------------------------------------------
robg - 10-08-2004 05:17 CEST
----------------------------------------------------------------------
Finally get some feedback from Cmedia. Following is copy of email
exchanges. I will attach documentation also received.

Dear Rob,
I'm sorry I missed your previous mail. I enclosed 8768 datasheet, register
spec and programming guide to you. 8768 is basically modified from 8738
and hence the 8738 programming guide is applicable. Hope them helpful.
Shall you have any specific question or further need, you can tell us
then.
BTW, our Linux driver developer is Chen-Li Tien (in CC list) and he is
also working on this. You can have a talk if you would like.
Regards,
Jason

I am still looking for information on programming the 8768 soundchip.
Can you provide a contact so I can can pursue this information.
Thank you for your time,

From: Rob Gordon <snip>
To: jason.liang@cmedia.com.tw
Dear Mr Liang,
I am working with the ALSA linux sound media team to implement a driver
for the new 8768 soundchip. This is currently used in the Soltek EQ3801
computer and there is a lot of interest in the Linux community to obtain
a working driver.
Since the technical details and an open source driver were available for
the 8738, I was hoping that the same level of information would be
published for the 8768 as well.
I am willing to work on the driver development if sufficient technical
documentation is provided, assuming a driver has not been prepared
already.
I have tried contacting the support group at Cmedia
(support@cmedia.com.tw ) several times but have not received any reply.
Can you assist in obtaining the information required or provide the name
of a contact person who could help?
Thank-you for your time.
Regards,
Rob Gordon

A good news! It will help for debugging. Thanks.
----------------------------------------------------------------------
tiwai - 10-08-2004 15:26 CEST
----------------------------------------------------------------------
According to the datasheet, CM8768 seems almost backward compatible
with CM8738 (6ch).
What did you mean in the original post, "none of the mixer settings I
change will take effect"? Isn't the mixer value changed at all, or
you get only the silent output, although the playback looks as if
working?
----------------------------------------------------------------------
tiwai - 10-08-2004 15:36 CEST
----------------------------------------------------------------------
Also, attach /etc/asound.state and /proc/asound/card0/cmipci for
debugging.
----------------------------------------------------------------------
patrick - 10-09-2004 09:30 CEST
----------------------------------------------------------------------
When I run a command like "amixer set Master 10" I get what looks like
proper output. The adjustments don't seem to stick though. Volume for
Master/PCM etc are always listed at 100% in alsamixer and even after
issuing the unmute command for PCM it is always listed as muted.
But if I try to use the ncurses program alsamixer none of the settings are

So yeah, I can't get any sound out of it and most audio programs either
give an error about not being able to access the device or just sit there

If you need any more information let me know, I'll try to help as best I

64bit kernel.

Yes I am using a 64-bit kernel. The motherboard this chip is built on is
an nforce3 250 board so as far as I know they are all 64 bit systems.
Maybe some one else has a 32bit kernel they can test it on but I do not.
----------------------------------------------------------------------
cltien - 10-16-2004 00:33 CEST
----------------------------------------------------------------------
Why increase I/O port address by 0x100? Is the port range assigned by BIOS
not working? Is this case for AMD 64-bit (and nForce3) system only?

Summary: CMedia 8768 Support
Description:
I've recently built a new computer with an on-board CMedia 8768 chip. This
chip is not listed as one of the supported CMedia chips (8738, etc.),
although I suspect that is because it is so new. Just wanted to let you
guys know it apparently doesn't work with the standard cmipci driver (at
least I think I'm doing everthing correctly -- I have a decent amount of
Linux experience but I'm no guru). Here is what I see though:
The card is recognized in /proc/asound as a CMedia 8738M6. However, if I
use a mixer like amixer or gnome-alsamixer none of the mixer settings I
change will take effect (and I am running these as root).
Any advice or comments would be appreciated. I'd be happy to help if you
think there is a possible fix.

By the way I'm on an AMD 64 machine if that makes a difference.
----------------------------------------------------------------------
robg - 07-27-2004 05:26 CEST
----------------------------------------------------------------------
Is there any progress on a driver for this chip?
It is used on the Soltek EQ3801 amd64 computer and a lot of people in
forums on other websites are interested in sound support.
I have the same problems as listed by drbobguy. I tested it under 64bit
kernel 2.6.7 I believe he did as well. I can setup a 32bit kernel and
retest if you fell its useful.
----------------------------------------------------------------------
tiwai - 07-30-2004 16:56 CEST
----------------------------------------------------------------------
Any datasheet available?
I don't know of...
----------------------------------------------------------------------
drbobguy - 07-31-2004 02:46 CEST
----------------------------------------------------------------------
I found this file off the CMedia website (I've attached it here):
http://www.cmedia.com.tw/doc/CMI8768%20Datasheet%20Rev%200.9.pdf
----------------------------------------------------------------------
robg - 07-31-2004 06:10 CEST
----------------------------------------------------------------------
The file from cmedia website does not contain any info for programming the
chip unfortunately. I have sent an email to cmedia requesting full
information. Will advise when I get a response.
Since the chip gives an ID of CMI8738-MC6 it may be very close to the
existing driver.
In the interim, is there any more information we can provide from /proc
that is useful?
----------------------------------------------------------------------
robg - 10-08-2004 05:17 CEST
----------------------------------------------------------------------
Finally get some feedback from Cmedia. Following is copy of email
exchanges. I will attach documentation also received.

Dear Rob,
I'm sorry I missed your previous mail. I enclosed 8768 datasheet, register
spec and programming guide to you. 8768 is basically modified from 8738
and hence the 8738 programming guide is applicable. Hope them helpful.
Shall you have any specific question or further need, you can tell us
then.
BTW, our Linux driver developer is Chen-Li Tien (in CC list) and he is
also working on this. You can have a talk if you would like.

Dear Mr Liang,
I am working with the ALSA linux sound media team to implement a driver
for the new 8768 soundchip. This is currently used in the Soltek EQ3801
computer and there is a lot of interest in the Linux community to obtain
a working driver.
Since the technical details and an open source driver were available for
the 8738, I was hoping that the same level of information would be
published for the 8768 as well.
I am willing to work on the driver development if sufficient technical
documentation is provided, assuming a driver has not been prepared
already.
I have tried contacting the support group at Cmedia
(support@cmedia.com.tw ) several times but have not received any reply.
Can you assist in obtaining the information required or provide the name
of a contact person who could help?
Thank-you for your time.
Regards,
Rob Gordon

A good news! It will help for debugging. Thanks.
----------------------------------------------------------------------
tiwai - 10-08-2004 15:26 CEST
----------------------------------------------------------------------
According to the datasheet, CM8768 seems almost backward compatible
with CM8738 (6ch).
What did you mean in the original post, "none of the mixer settings I
change will take effect"? Isn't the mixer value changed at all, or
you get only the silent output, although the playback looks as if
working?
----------------------------------------------------------------------
tiwai - 10-08-2004 15:36 CEST
----------------------------------------------------------------------
Also, attach /etc/asound.state and /proc/asound/card0/cmipci for
debugging.
----------------------------------------------------------------------
patrick - 10-09-2004 09:30 CEST
----------------------------------------------------------------------
When I run a command like "amixer set Master 10" I get what looks like
proper output. The adjustments don't seem to stick though. Volume for
Master/PCM etc are always listed at 100% in alsamixer and even after
issuing the unmute command for PCM it is always listed as muted.
But if I try to use the ncurses program alsamixer none of the settings are
adjustable. Likewise if I try to use beep-media-player it says it "can't
open audio."
So yeah, I can't get any sound out of it and most audio programs either
give an error about not being able to access the device or just sit there
and do nothing (like aplay).
If you need any more information let me know, I'll try to help as best I
can. Thank you!

I get the same problems as patrick for amixer and alsamixer operation. To
verify proper alsa setup, I disabled the 8768 in bios and installed a SB
es1371 and all controls and audio output works.
I use AMD 64-bit kernel 2.6.8-rc2.
I will attach /etc/asound.state and /proc/asound/card0/cmipci as
suggested.
----------------------------------------------------------------------
robg - 10-10-2004 04:57 CEST
----------------------------------------------------------------------
I checked and my /etc/asound.state and /proc/asound/card0/cmipci were
identical to those uploaded by patrick so I didn't upload them.
Using aplay I get the following error:
#aplay /usr/lib/mozilla/res/samples/test.wav

tiwai - 10-13-2004 16:37 CEST

The register dump is all ff, that is, the driver is reading wrong I/O
ports.
Can you show the output of "lspci -xvv" ?
----------------------------------------------------------------------
tiwai - 10-13-2004 16:37 CEST
----------------------------------------------------------------------
Also, please use 1.0.7-rc2 for avoid unnecessary differences.

Please try the attached patch (just for testing).
----------------------------------------------------------------------
patrick - 10-14-2004 16:05 CEST
----------------------------------------------------------------------
I gave the patch a try just now and I can't seem to produce any different
results. I only had a moment to poke at it though since I am off to work
now.
Maybe some one else will have more luck with it?
Thank you for doing all of this by the way!
----------------------------------------------------------------------
tiwai - 10-14-2004 16:19 CEST
----------------------------------------------------------------------
Did you check /proc/asound/card0/cmipci? Now it should address d400.
BTW, do you have a 32bit system on it? It might be a problem of
64bit kernel.
----------------------------------------------------------------------
patrick - 10-14-2004 23:57 CEST
----------------------------------------------------------------------
Yeah, it seems to be:
C-Media PCI CMI8738-MC6 (model 39) at 0xd400, irq 12
00: ff ff ff ff
04: ff ff ff ff
08: ff ff ff ff

28: ff ff ff ff
2c: ff ff ff ff
30: ff ff ff ff
34: ff ff ff ff
38: ff ff ff ff
3c: ff ff ff ff
Yes I am using a 64-bit kernel. The motherboard this chip is built on is
an nforce3 250 board so as far as I know they are all 64 bit systems.
Maybe some one else has a 32bit kernel they can test it on but I do not.
----------------------------------------------------------------------
cltien - 10-16-2004 00:33 CEST
----------------------------------------------------------------------
Why increase I/O port address by 0x100? Is the port range assigned by BIOS
not working? Is this case for AMD 64-bit (and nForce3) system only?

----------------------------------------------------------------------
robg - 10-16-2004 07:32 CEST
----------------------------------------------------------------------
I have been doing some additional testing and I think cltien is right.
I have rebuilt my system to run a 32 bit kernel (vanilla 2.6.7) on the
EQ3801 and I get the same problems. So it is not a 64 bit kernel issue.
I also installed an es1371 soundcard and it works properly so basic alsa
is ok.
I added a printk to snd_cmipci_proc_read:
printk(KERN_INFO "cmipci: proc read iobase=0x%lx\n", cm->iobase);
And dmesg shows:
cmipci: proc_read iobase=0xd200
And lspci -xvv shows I/O ports at 0xd200 so offset is not the problem.
But cat /proc/asound/card0/cmipci shows same as patrick posted with ff for
all register values.
There seems to be some success with 8768 PCI cards for current driver:
http://www.linuxquestions.org/questions/history/234279
So is it possible the Soltek EQ3801/nforce3 needs additional
initialization?
Anything else I can investigate?

I gave the patch a try just now and I can't seem to produce any different

Did you check /proc/asound/card0/cmipci? Now it should address d400.
BTW, do you have a 32bit system on it? It might be a problem of
64bit kernel.
----------------------------------------------------------------------
patrick - 10-14-2004 23:57 CEST

Yeah, it seems to be:

Yes I am using a 64-bit kernel. The motherboard this chip is built on is
an nforce3 250 board so as far as I know they are all 64 bit systems.
Maybe some one else has a 32bit kernel they can test it on but I do not.
----------------------------------------------------------------------
cltien - 10-16-2004 00:33 CEST
----------------------------------------------------------------------
Why increase I/O port address by 0x100? Is the port range assigned by BIOS
not working? Is this case for AMD 64-bit (and nForce3) system only?

----------------------------------------------------------------------
robg - 10-16-2004 07:32 CEST
----------------------------------------------------------------------
I have been doing some additional testing and I think cltien is right.
I have rebuilt my system to run a 32 bit kernel (vanilla 2.6.7) on the
EQ3801 and I get the same problems. So it is not a 64 bit kernel issue.
I also installed an es1371 soundcard and it works properly so basic alsa
is ok.
I added a printk to snd_cmipci_proc_read:
printk(KERN_INFO "cmipci: proc read iobase=0x%lx\n", cm->iobase);
And dmesg shows:
cmipci: proc_read iobase=0xd200
And lspci -xvv shows I/O ports at 0xd200 so offset is not the problem.
But cat /proc/asound/card0/cmipci shows same as patrick posted with ff for
all register values.
There seems to be some success with 8768 PCI cards for current driver:
http://www.linuxquestions.org/questions/history/234279
So is it possible the Soltek EQ3801/nforce3 needs additional
initialization?
Anything else I can investigate?
----------------------------------------------------------------------
tiwai - 10-18-2004 11:32 CEST
----------------------------------------------------------------------
The offset 0x100 was just for testing because the value of BIOS setting
looks different from the default value in the spec.

Summary: CMedia 8768 Support
Description:
I've recently built a new computer with an on-board CMedia 8768 chip. This
chip is not listed as one of the supported CMedia chips (8738, etc.),
although I suspect that is because it is so new. Just wanted to let you
guys know it apparently doesn't work with the standard cmipci driver (at
least I think I'm doing everthing correctly -- I have a decent amount of
Linux experience but I'm no guru). Here is what I see though:
The card is recognized in /proc/asound as a CMedia 8738M6. However, if I
use a mixer like amixer or gnome-alsamixer none of the mixer settings I
change will take effect (and I am running these as root).
Any advice or comments would be appreciated. I'd be happy to help if you
think there is a possible fix.
======================================================================

By the way I'm on an AMD 64 machine if that makes a difference.
----------------------------------------------------------------------
robg - 07-27-2004 05:26 CEST
----------------------------------------------------------------------
Is there any progress on a driver for this chip?
It is used on the Soltek EQ3801 amd64 computer and a lot of people in
forums on other websites are interested in sound support.
I have the same problems as listed by drbobguy. I tested it under 64bit
kernel 2.6.7 I believe he did as well. I can setup a 32bit kernel and
retest if you fell its useful.
----------------------------------------------------------------------
tiwai - 07-30-2004 16:56 CEST
----------------------------------------------------------------------
Any datasheet available?
I don't know of...
----------------------------------------------------------------------
drbobguy - 07-31-2004 02:46 CEST
----------------------------------------------------------------------
I found this file off the CMedia website (I've attached it here):
http://www.cmedia.com.tw/doc/CMI8768%20Datasheet%20Rev%200.9.pdf
----------------------------------------------------------------------
robg - 07-31-2004 06:10 CEST
----------------------------------------------------------------------
The file from cmedia website does not contain any info for programming the
chip unfortunately. I have sent an email to cmedia requesting full
information. Will advise when I get a response.
Since the chip gives an ID of CMI8738-MC6 it may be very close to the
existing driver.
In the interim, is there any more information we can provide from /proc
that is useful?
----------------------------------------------------------------------
robg - 10-08-2004 05:17 CEST
----------------------------------------------------------------------
Finally get some feedback from Cmedia. Following is copy of email
exchanges. I will attach documentation also received.

Dear Rob,
I'm sorry I missed your previous mail. I enclosed 8768 datasheet, register
spec and programming guide to you. 8768 is basically modified from 8738
and hence the 8738 programming guide is applicable. Hope them helpful.
Shall you have any specific question or further need, you can tell us
then.
BTW, our Linux driver developer is Chen-Li Tien (in CC list) and he is
also working on this. You can have a talk if you would like.
Regards,
Jason

From: Rob Gordon <snip>
To: jason.liang@cmedia.com.tw
Dear Mr Liang,
I am working with the ALSA linux sound media team to implement a driver
for the new 8768 soundchip. This is currently used in the Soltek EQ3801
computer and there is a lot of interest in the Linux community to obtain
a working driver.
Since the technical details and an open source driver were available for
the 8738, I was hoping that the same level of information would be
published for the 8768 as well.
I am willing to work on the driver development if sufficient technical
documentation is provided, assuming a driver has not been prepared
already.
I have tried contacting the support group at Cmedia
(support@cmedia.com.tw ) several times but have not received any reply.
Can you assist in obtaining the information required or provide the name
of a contact person who could help?
Thank-you for your time.
Regards,
Rob Gordon

A good news! It will help for debugging. Thanks.
----------------------------------------------------------------------
tiwai - 10-08-2004 15:26 CEST
----------------------------------------------------------------------
According to the datasheet, CM8768 seems almost backward compatible
with CM8738 (6ch).
What did you mean in the original post, "none of the mixer settings I
change will take effect"? Isn't the mixer value changed at all, or
you get only the silent output, although the playback looks as if
working?
----------------------------------------------------------------------
tiwai - 10-08-2004 15:36 CEST
----------------------------------------------------------------------
Also, attach /etc/asound.state and /proc/asound/card0/cmipci for
debugging.
----------------------------------------------------------------------
patrick - 10-09-2004 09:30 CEST
----------------------------------------------------------------------
When I run a command like "amixer set Master 10" I get what looks like
proper output. The adjustments don't seem to stick though. Volume for
Master/PCM etc are always listed at 100% in alsamixer and even after
issuing the unmute command for PCM it is always listed as muted.
But if I try to use the ncurses program alsamixer none of the settings are
adjustable. Likewise if I try to use beep-media-player it says it "can't
open audio."
So yeah, I can't get any sound out of it and most audio programs either
give an error about not being able to access the device or just sit there
and do nothing (like aplay).
If you need any more information let me know, I'll try to help as best I
can. Thank you!

I get the same problems as patrick for amixer and alsamixer operation. To
verify proper alsa setup, I disabled the 8768 in bios and installed a SB
es1371 and all controls and audio output works.
I use AMD 64-bit kernel 2.6.8-rc2.
I will attach /etc/asound.state and /proc/asound/card0/cmipci as
suggested.

----------------------------------------------------------------------
cltien - 10-18-2004 23:00 CEST
----------------------------------------------------------------------
The 0xd400 is just power-up value for PCI configuration, the BIOS can
change it when booting. Use the value returned in any case.
The problem looks like either I/O enabled or Bus Master Enabled not set in
PCI configuration, but the lspci output shown they are set. I am afraid
something wrong with nForce3 with Linux kernel.
Can you add pci_set_master() in the chip initialization procedure?

Summary: CMedia 8768 Support
Description:
I've recently built a new computer with an on-board CMedia 8768 chip. This
chip is not listed as one of the supported CMedia chips (8738, etc.),
although I suspect that is because it is so new. Just wanted to let you
guys know it apparently doesn't work with the standard cmipci driver (at
least I think I'm doing everthing correctly -- I have a decent amount of
Linux experience but I'm no guru). Here is what I see though:
The card is recognized in /proc/asound as a CMedia 8738M6. However, if I
use a mixer like amixer or gnome-alsamixer none of the mixer settings I
change will take effect (and I am running these as root).
Any advice or comments would be appreciated. I'd be happy to help if you
think there is a possible fix.

By the way I'm on an AMD 64 machine if that makes a difference.
----------------------------------------------------------------------
robg - 07-27-2004 05:26 CEST
----------------------------------------------------------------------
Is there any progress on a driver for this chip?
It is used on the Soltek EQ3801 amd64 computer and a lot of people in
forums on other websites are interested in sound support.
I have the same problems as listed by drbobguy. I tested it under 64bit
kernel 2.6.7 I believe he did as well. I can setup a 32bit kernel and
retest if you fell its useful.
----------------------------------------------------------------------
tiwai - 07-30-2004 16:56 CEST
----------------------------------------------------------------------
Any datasheet available?
I don't know of...
----------------------------------------------------------------------
drbobguy - 07-31-2004 02:46 CEST
----------------------------------------------------------------------
I found this file off the CMedia website (I've attached it here):
http://www.cmedia.com.tw/doc/CMI8768%20Datasheet%20Rev%200.9.pdf
----------------------------------------------------------------------
robg - 07-31-2004 06:10 CEST
----------------------------------------------------------------------
The file from cmedia website does not contain any info for programming the
chip unfortunately. I have sent an email to cmedia requesting full
information. Will advise when I get a response.
Since the chip gives an ID of CMI8738-MC6 it may be very close to the
existing driver.
In the interim, is there any more information we can provide from /proc
that is useful?
----------------------------------------------------------------------
robg - 10-08-2004 05:17 CEST
----------------------------------------------------------------------
Finally get some feedback from Cmedia. Following is copy of email
exchanges. I will attach documentation also received.

Dear Rob,
I'm sorry I missed your previous mail. I enclosed 8768 datasheet, register
spec and programming guide to you. 8768 is basically modified from 8738
and hence the 8738 programming guide is applicable. Hope them helpful.
Shall you have any specific question or further need, you can tell us
then.
BTW, our Linux driver developer is Chen-Li Tien (in CC list) and he is
also working on this. You can have a talk if you would like.
Regards,
Jason

From: Rob Gordon <snip>
To: jason.liang@cmedia.com.tw
Dear Mr Liang,
I am working with the ALSA linux sound media team to implement a driver
for the new 8768 soundchip. This is currently used in the Soltek EQ3801
computer and there is a lot of interest in the Linux community to obtain
a working driver.
Since the technical details and an open source driver were available for
the 8738, I was hoping that the same level of information would be
published for the 8768 as well.
I am willing to work on the driver development if sufficient technical
documentation is provided, assuming a driver has not been prepared
already.
I have tried contacting the support group at Cmedia
(support@cmedia.com.tw ) several times but have not received any reply.
Can you assist in obtaining the information required or provide the name
of a contact person who could help?
Thank-you for your time.
Regards,
Rob Gordon

A good news! It will help for debugging. Thanks.
----------------------------------------------------------------------
tiwai - 10-08-2004 15:26 CEST
----------------------------------------------------------------------
According to the datasheet, CM8768 seems almost backward compatible
with CM8738 (6ch).
What did you mean in the original post, "none of the mixer settings I
change will take effect"? Isn't the mixer value changed at all, or
you get only the silent output, although the playback looks as if
working?
----------------------------------------------------------------------
tiwai - 10-08-2004 15:36 CEST
----------------------------------------------------------------------
Also, attach /etc/asound.state and /proc/asound/card0/cmipci for
debugging.
----------------------------------------------------------------------
patrick - 10-09-2004 09:30 CEST
----------------------------------------------------------------------
When I run a command like "amixer set Master 10" I get what looks like
proper output. The adjustments don't seem to stick though. Volume for
Master/PCM etc are always listed at 100% in alsamixer and even after
issuing the unmute command for PCM it is always listed as muted.
But if I try to use the ncurses program alsamixer none of the settings are
adjustable. Likewise if I try to use beep-media-player it says it "can't
open audio."
So yeah, I can't get any sound out of it and most audio programs either
give an error about not being able to access the device or just sit there
and do nothing (like aplay).
If you need any more information let me know, I'll try to help as best I
can. Thank you!

I get the same problems as patrick for amixer and alsamixer operation. To
verify proper alsa setup, I disabled the 8768 in bios and installed a SB
es1371 and all controls and audio output works.
I use AMD 64-bit kernel 2.6.8-rc2.
I will attach /etc/asound.state and /proc/asound/card0/cmipci as
suggested.
----------------------------------------------------------------------
robg - 10-10-2004 04:57 CEST
----------------------------------------------------------------------
I checked and my /etc/asound.state and /proc/asound/card0/cmipci were
identical to those uploaded by patrick so I didn't upload them.
Using aplay I get the following error:
#aplay /usr/lib/mozilla/res/samples/test.wav

tiwai - 10-13-2004 16:37 CEST

The register dump is all ff, that is, the driver is reading wrong I/O
ports.
Can you show the output of "lspci -xvv" ?
----------------------------------------------------------------------
tiwai - 10-13-2004 16:37 CEST
----------------------------------------------------------------------
Also, please use 1.0.7-rc2 for avoid unnecessary differences.

Please try the attached patch (just for testing).
----------------------------------------------------------------------
patrick - 10-14-2004 16:05 CEST
----------------------------------------------------------------------
I gave the patch a try just now and I can't seem to produce any different
results. I only had a moment to poke at it though since I am off to work
now.
Maybe some one else will have more luck with it?
Thank you for doing all of this by the way!
----------------------------------------------------------------------
tiwai - 10-14-2004 16:19 CEST
----------------------------------------------------------------------
Did you check /proc/asound/card0/cmipci? Now it should address d400.
BTW, do you have a 32bit system on it? It might be a problem of
64bit kernel.
----------------------------------------------------------------------
patrick - 10-14-2004 23:57 CEST
----------------------------------------------------------------------
Yeah, it seems to be:
C-Media PCI CMI8738-MC6 (model 39) at 0xd400, irq 12
00: ff ff ff ff
04: ff ff ff ff
08: ff ff ff ff

Yes I am using a 64-bit kernel. The motherboard this chip is built on is
an nforce3 250 board so as far as I know they are all 64 bit systems.
Maybe some one else has a 32bit kernel they can test it on but I do not.
----------------------------------------------------------------------
cltien - 10-16-2004 00:33 CEST
----------------------------------------------------------------------
Why increase I/O port address by 0x100? Is the port range assigned by BIOS
not working? Is this case for AMD 64-bit (and nForce3) system only?

----------------------------------------------------------------------
robg - 10-16-2004 07:32 CEST
----------------------------------------------------------------------
I have been doing some additional testing and I think cltien is right.
I have rebuilt my system to run a 32 bit kernel (vanilla 2.6.7) on the
EQ3801 and I get the same problems. So it is not a 64 bit kernel issue.
I also installed an es1371 soundcard and it works properly so basic alsa
is ok.
I added a printk to snd_cmipci_proc_read:
printk(KERN_INFO "cmipci: proc read iobase=0x%lx\n", cm->iobase);
And dmesg shows:
cmipci: proc_read iobase=0xd200
And lspci -xvv shows I/O ports at 0xd200 so offset is not the problem.
But cat /proc/asound/card0/cmipci shows same as patrick posted with ff for
all register values.
There seems to be some success with 8768 PCI cards for current driver:
http://www.linuxquestions.org/questions/history/234279
So is it possible the Soltek EQ3801/nforce3 needs additional
initialization?
Anything else I can investigate?
----------------------------------------------------------------------
tiwai - 10-18-2004 11:32 CEST
----------------------------------------------------------------------
The offset 0x100 was just for testing because the value of BIOS setting
looks different from the default value in the spec.
----------------------------------------------------------------------
cltien - 10-18-2004 23:00 CEST
----------------------------------------------------------------------
The 0xd400 is just power-up value for PCI configuration, the BIOS can
change it when booting. Use the value returned in any case.
The problem looks like either I/O enabled or Bus Master Enabled not set in
PCI configuration, but the lspci output shown they are set. I am afraid
something wrong with nForce3 with Linux kernel.
Can you add pci_set_master() in the chip initialization procedure?
Regards,
ChenLi Tien
----------------------------------------------------------------------
robg - 10-19-2004 05:35 CEST
----------------------------------------------------------------------
pci_set_master() already exists in snd_cmipci_create() and is set before
the call to query_chip().
Anything else to look for?
Anything we can ask the manufacturer (Soltek?) that may shed some light?

I also have installed a QBIC 3801 Barebone and also have the problem with
the CMEDIA 8768.
Same problems as mentioned above. Is there a way to get this soundchip

Hello there,
I also have installed a QBIC 3801 Barebone and also have the problem with
the CMEDIA 8768.
Same problems as mentioned above. Is there a way to get this soundchip
working?
Or how could I help supporting it, I'm no programmer but perhaps I can
help another way

I tested this board (Soltek EQ3801) and found that the on-board codec
cannot be accessed in DOS. It cannot betested by our DOS diagonal program
, but a add-on card can.
I guess that the BIOS doesn't initialize the on-board codec correctly.
Does ayone has this kind of problem with another mother board?

Summary: CMedia 8768 Support
Description:
I've recently built a new computer with an on-board CMedia 8768 chip. This
chip is not listed as one of the supported CMedia chips (8738, etc.),
although I suspect that is because it is so new. Just wanted to let you
guys know it apparently doesn't work with the standard cmipci driver (at
least I think I'm doing everthing correctly -- I have a decent amount of
Linux experience but I'm no guru). Here is what I see though:
The card is recognized in /proc/asound as a CMedia 8738M6. However, if I
use a mixer like amixer or gnome-alsamixer none of the mixer settings I
change will take effect (and I am running these as root).
Any advice or comments would be appreciated. I'd be happy to help if you
think there is a possible fix.

Good news,
There's a new beta of the soltek bios availible,
just send Lydia an email and she will send you the BIOS beta for testing.

Ok, the BIOS engineer is has done a good job.
The BIOS works for me and I can use alsa with the cmedia soundchip.
After flashing the beta bios, I get a CRC Error on booting and have to
press F1 to continue, but everything works after that, so the Soltek
people are on a good way.

Summary: CMedia 8768 Support
Description:
I've recently built a new computer with an on-board CMedia 8768 chip. This
chip is not listed as one of the supported CMedia chips (8738, etc.),
although I suspect that is because it is so new. Just wanted to let you
guys know it apparently doesn't work with the standard cmipci driver (at
least I think I'm doing everthing correctly -- I have a decent amount of
Linux experience but I'm no guru). Here is what I see though:
The card is recognized in /proc/asound as a CMedia 8738M6. However, if I
use a mixer like amixer or gnome-alsamixer none of the mixer settings I
change will take effect (and I am running these as root).
Any advice or comments would be appreciated. I'd be happy to help if you
think there is a possible fix.

Sound is working fine for me too with the beta bios without error message.
I've tested it on Fedora Core 3 x86_64 and Suse 9.2 x86_64. With FC3, the
C-Media PCI CMI8738 is automatically discovered and the snd-cmipci driver
loaded by alsasound. Yast from Suse found a CMI8738/C3DX audio device and
load the cmipci driver with alsasound. Everything seems to work fine.
In order to flash without floppy drive, i used a bootable cd from
http://www.nu2.nu/bootcd and just add the bios bin file and the flash
utility. It worked prefectly.
So, it is a good new indeed.
