Thank's for the quick response and analysis. Regretabbly,
I won't have test results until 27 Dec 04 (after the Holiday).
However, I believe the codec chip does get left at its
default rate. If you can think of anything else for me to try,
post it *before 1630 EST today*.
Recall that the original 1.0.7 ALSA driver does work approx 10% of the
time.
Let me highlight something in the alsa_codec_init file I uploaded:
...
reg 0x2a read 0x0000 VRA off
reg 0x2a write 0x0001 VRA enable
reg 0x2c write 0x2af8 11 kHz
reg 0x2c read 0x2af8
...
reg 0x2c write 0xac44 44.1 kHz
reg 0x2c read 0xac44
reg 0x2c write 0xbb80 48 kHz (codec default based on AK4544A specs)
reg 0x2c read 0xbb80
.... (DRA probes don't seem to follow. I might
be wrong.)
reg 0x2a read 0x0001 VRA enabled
reg 0x2a write 0x0001 VRA enable (why? Maybe it should be followed
with a
reg 0x2c write 0xbb80
?)

Maybe you're right. 48kHz is probed as the last, so it should remain 48k.
If the VRA is really culprit, you can turn on/off dynamically by writing
/proc/asound/card0/codec97#0/ac97#0-0+regs files like:
echo 2a 0000 > /proc/asound/card0/codec97#0/ac97#0-0+regs
If changing VRA triggers/removes the cracky sound, we can simply add a
sequence to disable VRA in ymfpci, since it doesn't need VRA anyway.

Neither "ac97-default-rate-fix.diff" nor "ymfpci-novra.diff"
solved the problem.
Testing using the /proc interface with "tecra8100demo.patch"
in place revealed:
- turing VRA on & off without changing the rate did not induce the
problem
- turning on VRA and changing the rate in register 0x2c away from 48
Khz
and then back to 48 KHz always induced the problem (except in one
trial)
- trying to set the rate back to 48 Khz and/or turning off VRA does
not
make the problem go away, once induced
I conclude that simply changing the rate induces the problem. Once
induced
the problem cannot be reversed except via chipset reset. To date it
appears that
the only solution for this laptop is to prevent VRA rate changes
altogether (including the probe).
I'd be happy with an ac97_codec module option to prevent VRA rate probes
and enables.
I wanted to test more, like not allowing the modem rate register (0x32?)
to change,
since I don't think it's a valid register for this chip, and then see if
VRA works.
But honestly, I don't have the time.

The latest CVS already includes the change for ac97_codec.c. The rate
detection is no longer performed for non-vra case.

Maybe you're right. 48kHz is probed as the last, so it should remain 48k.
If the VRA is really culprit, you can turn on/off dynamically by writing
/proc/asound/card0/codec97#0/ac97#0-0+regs files like:
echo 2a 0000 > /proc/asound/card0/codec97#0/ac97#0-0+regs
If changing VRA triggers/removes the cracky sound, we can simply add a
sequence to disable VRA in ymfpci, since it doesn't need VRA anyway.

Great, thanks for spotting the problem!
I've never thought of ac97-releated problems.
My rough guess about this problem is that ac97_codec routine changes the
sample rate to determine the supported rates, and left as unusual
(non-48k) rate. YMFPCI doesn't require VRA since the chip itself does.
Hence, a strange VRA conflicts with the expected rate of YMFPCI. If the
situation is really like I guess, putting back the default rate would
help.
Or, the AK4544 codec is really screwed up...
Anyay, the patch is attached. I know you can't answer soon, but try if
you have time :)
----------------------------------------------------------------------
wallsga - 12-20-04 17:25
----------------------------------------------------------------------
Thank's for the quick response and analysis. Regretabbly,
I won't have test results until 27 Dec 04 (after the Holiday).
However, I believe the codec chip does get left at its
default rate. If you can think of anything else for me to try,
post it *before 1630 EST today*.
Recall that the original 1.0.7 ALSA driver does work
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=5#10% of the time.
Let me highlight something in the alsa_codec_init file I uploaded:
...
reg 0x2a read 0x0000 VRA off
reg 0x2a write 0x0001 VRA enable
reg 0x2c write 0x2af8 11 kHz
reg 0x2c read 0x2af8
...
reg 0x2c write 0xac44 44.1 kHz
reg 0x2c read 0xac44
reg 0x2c write 0xbb80 48 kHz (codec default based on AK4544A specs)
reg 0x2c read 0xbb80
.... (DRA probes don't seem to follow. I might
be wrong.)
reg 0x2a read 0x0001 VRA enabled
reg 0x2a write 0x0001 VRA enable (why? Maybe it should be followed
with a
reg 0x2c write 0xbb80
?)

Summary: Crackly PCM output.
Description:
When playing a sound through the speakers on Toshiba Tecra 8100 the only
sound produced is noise.

wallsga - 12-20-04 16:08

17 Dec 04: Causal relationship found:
During AK4544 AC'97 codec initializaton, by keeping VRA
disabled (and thus also preventing the rate probes),
I was able to have sound on the Tecra 8100 every time
I loaded the alsa-1.0.7 driver.
(Sound quality still seems inferior to OSS, but that's
another issue)
The attached tecra8100demo.patch will allow others
to verify this. This demo patch is completely improper
as a long term fix.
The attached archive codec-init-seq.tar.gz has dumps
of the OSS and ALSA drivers' codec initialization
sequences (before applying the demo patch to ALSA).
Please keep in mind that writes to some YMF744
registers also perform codec reads & writes which
aren't logged.
I can only speculate as to what the real problem is:
- AK4544 is a buggy chip wrt VRA ?
- AK4544 can handle reads/writes to non-existant regs ?
- AK4544 needs a more specific sequence to use VRA ?
- YMF744 provides a BIT_CLOCK to the AK4544 instead
of having a crystal (?) and this causes VRA problems ?
TODO (by someone other than me):
- Get a datasheet for the discontinued AK4544 from AKM
(i.e. Register 0x22, 3D Control, seems to differ from the AK4544A)
- Other tecra8100 or YMF7x4/AK4544 users validate the demo patch.
- Write a proper fix for ALSA which properly detects and compensates
for the AK4544.
- Figure out how to get VRA working properly with this codec/laptop.
- Figure out the source of the remaining soft "whistles" and "creaks"
that OSS does not seem to exhibit
- Figure out why the volume seems lower compared to OSS
I am available to beta test full blown proper patches for this problem
with a short (24 hour minimum) turn-around time.
I am not readily available to respond to "could you try this...?"
requests in a timely manner. I could barely time find to debug what I
did.

Great, thanks for spotting the problem!
I've never thought of ac97-releated problems.
My rough guess about this problem is that ac97_codec routine changes the
sample rate to determine the supported rates, and left as unusual
(non-48k) rate. YMFPCI doesn't require VRA since the chip itself does.
Hence, a strange VRA conflicts with the expected rate of YMFPCI. If the
situation is really like I guess, putting back the default rate would
help.
Or, the AK4544 codec is really screwed up...
Anyay, the patch is attached. I know you can't answer soon, but try if
you have time :)

Lookin at some *BSD code and some AKM documents, the codec on board

which was in mass production, but now discontinued by the manufacturer.
The datasheet for the AK4544A says it's vendor ID is AKM6.
The datasheet for the AK4544 is unavailable from the vendor's website.
Hopefully they're close enough.

Summary: Crackly PCM output.
Description:
When playing a sound through the speakers on Toshiba Tecra 8100 the only
sound produced is noise.
======================================================================
----------------------------------------------------------------------
wallsga - 11-23-04 16:15
----------------------------------------------------------------------
Attaching file tecra8100-bug-data.tar.gz.
In the following note
"working" means "pcm playback of a .wav file through
the Tecra8100's built-in speakers is
acceptable to the human ear"
"oss driver" means "the yfmpci driver supplied with the
Redhat 9.0/linux-2.4.20-8 distribution"
"alsa driver" means "the snd-ymfpci driver and supporting
modules provided by alsa-drivers-1.0.7"
1) In the uploaded archive, "lspci.oss" and "lspci.alsa" give
the "lspci -xxxvv" dumps with the oss and alsa driver loaded
respectively. The alsa driver was not working at this time.
Note the "Legacy Audio Control" PCI Configuration Register (0x40-0x41)
is different. OSS leaves it at the chipset default (0x907f), alsa
zeros it.
I modified my alsa driver to write the "old_legacy_ctrl" value
back to this register right after reading it, instead of writing
"legacy_ctrl" to the register. As I expected, it had no effect
on the problem.
In other "lspci" output in the archive, you will notice this change
in my alsa driver's behavior.
2) I conclude that loading & unloading the oss driver before the
alsa driver is not a work-around, simply a superstition. It seems to
have no bearing on whether the alsa driver will work.
The only method that I came up with to get the alsa driver working
properly
was to repeat the following sequence until the sound was acceptable:
rmmod `lsmod | awk '/^snd/ {print $1}' | grep -v page`
rmmod soundcore
modprobe snd-card-0
/bin/aumix-minimal -f /etc/.aumixrc -L
aplay /usr/share/sounds/(somefile).wav
As a guess, the alsa driver worked properly in less than < 10% of the
load attempts.
This type of response indicates an uninitialized variable problem to
me. But that may not jibe with being a Tecra8100 specific problem.
(I suggest that we reconsider if this is a Tecra8100 only problem.)
3) The oss driver *always* works.
4) Diffs of /proc/asound/card0/codec97#0/* and lscpi output between
alsa working and alsa not working yield zero differences.
5) Diffs of /proc/asound/card0/ymfpci between alsa working and alsa
not working sometimes show differences to register 0x60 and the one that
follows (AC97CMDDATA and AC97CMDADDR, IIRC), sometimes show differences
to the last four registers (PLAYBACKCTRLADDR, EFFECTSCTRLADDR,
RECORDCTRLADDR,
& WORKBASE, IIRC), and sometimes show differences to both sets.
I modified my oss driver to dump the values for the
last four registers as it loaded them. OSS would work using the same
values in the last four registers as a non-working alsa driver load.
A working alsa driver load and a non-working alsa driver load could use
the same values in the last four registers.
6) Added mdelay(20) to the alsa driver after the image load (in addition
to the udelay(100)) just like the oss driver. This had no effect.
7) Watching /proc/interrupts and (a)play-ing a particular wave file:
- oss driver always used 51 interrupts
- non-working alsa driver load always used 74(? IIRC) interrupts
- non-working alsa driver load oss-emulation always used 67 (? IIRC)
interrupts
That's as much as I can do on this problem until 01 Dec.
I'd really like to get rosegarden working on this laptop. I hope this
helps.

Summary: Crackly PCM output.
Description:
When playing a sound through the speakers on Toshiba Tecra 8100 the only
sound produced is noise.

Attaching file tecra8100-bug-data.tar.gz.
In the following note
"working" means "pcm playback of a .wav file through
the Tecra8100's built-in speakers is
acceptable to the human ear"
"oss driver" means "the yfmpci driver supplied with the
Redhat 9.0/linux-2.4.20-8 distribution"
"alsa driver" means "the snd-ymfpci driver and supporting
modules provided by alsa-drivers-1.0.7"
1) In the uploaded archive, "lspci.oss" and "lspci.alsa" give
the "lspci -xxxvv" dumps with the oss and alsa driver loaded
respectively. The alsa driver was not working at this time.
Note the "Legacy Audio Control" PCI Configuration Register (0x40-0x41)
is different. OSS leaves it at the chipset default (0x907f), alsa
zeros it.
I modified my alsa driver to write the "old_legacy_ctrl" value
back to this register right after reading it, instead of writing
"legacy_ctrl" to the register. As I expected, it had no effect
on the problem.
In other "lspci" output in the archive, you will notice this change
in my alsa driver's behavior.
2) I conclude that loading & unloading the oss driver before the
alsa driver is not a work-around, simply a superstition. It seems to
have no bearing on whether the alsa driver will work.
The only method that I came up with to get the alsa driver working
properly
was to repeat the following sequence until the sound was acceptable:
rmmod `lsmod | awk '/^snd/ {print $1}' | grep -v page`
rmmod soundcore
modprobe snd-card-0
/bin/aumix-minimal -f /etc/.aumixrc -L
aplay /usr/share/sounds/(somefile).wav
As a guess, the alsa driver worked properly in less than < 10% of the
load attempts.
This type of response indicates an uninitialized variable problem to
me. But that may not jibe with being a Tecra8100 specific problem.
(I suggest that we reconsider if this is a Tecra8100 only problem.)
3) The oss driver *always* works.
4) Diffs of /proc/asound/card0/codec97#0/* and lscpi output between
alsa working and alsa not working yield zero differences.
5) Diffs of /proc/asound/card0/ymfpci between alsa working and alsa
not working sometimes show differences to register 0x60 and the one that
follows (AC97CMDDATA and AC97CMDADDR, IIRC), sometimes show differences
to the last four registers (PLAYBACKCTRLADDR, EFFECTSCTRLADDR,
RECORDCTRLADDR,
& WORKBASE, IIRC), and sometimes show differences to both sets.
I modified my oss driver to dump the values for the
last four registers as it loaded them. OSS would work using the same
values in the last four registers as a non-working alsa driver load.
A working alsa driver load and a non-working alsa driver load could use
the same values in the last four registers.
6) Added mdelay(20) to the alsa driver after the image load (in addition
to the udelay(100)) just like the oss driver. This had no effect.
7) Watching /proc/interrupts and (a)play-ing a particular wave file:
- oss driver always used 51 interrupts
- non-working alsa driver load always used 74(? IIRC) interrupts
- non-working alsa driver load oss-emulation always used 67 (? IIRC)
interrupts
That's as much as I can do on this problem until 01 Dec.
I'd really like to get rosegarden working on this laptop. I hope this
helps.

Confirmation:

alsa-drivers-1.0.7
The following works for me *sometimes*:
(edit /etc/modules.conf to comment out alsa stuff)
modprobe ymfpci
play /usr/share/sounds/KDE_Beep_Ahem.wav
(sound plays)
rmmod -r ymfpci
(edit /etc/modules.conf to uncomment alsa stuff)
/etc/init.d/alsasound start
alsamixer
(verify things aren't muted)
aplay /usr/share/sounds/KDE_Beep_Ahem.wav
(sound plays or it doesn't, but if it does, I can continue to play more
files)
It appears to be essential that I play a sound while the OSS driver is
loader.

Maybe my request was not clear.
Please do the following:
1. Load ALSA snd-ymfpci after the fresh boot.
Dump /proc/asound/card0/ymfpci, lspci -xxxvv.
(also /proc/asound/card0/codec97#0/* files, too)
2. Unload snd-ymfpci, then load OSS ymfpci module.
3. Unload ymfpci, then again load ALSA snd-ymfpci module.
Dump the same files as 1.

I don't have /proc/asound/card0/ymfpci
When i do 'locate ymfpci' it appears in /sys/module/ymfpci/ and
/sys/bus/pci/drivers/ymfpci/ because I am using sysfs. Where can I compare
the registers now?

I don't have /proc/asound/card0/ymfpci
When i do 'locate ymfpci' it appears in /sys/module/ymfpci/ and
/sys/bus/pci/drivers/ymfpci/ because I am using sysfs. Where can I compare
the registers now?

Yeah I know it's a known long-standing bug. Just no time to look at this
yet.
It's likely a missing or wrong initialization of registers.
To compare the registers, please check /proc/asound/card0/ymfpci before
and after loading the OSS ymfpci module. Also, check the output of "lspci
-xxxvv" before and after the OSS, too.

Why is this bug still unassigned? This worked in the 0.5 series and it's an
old bug. I'm not bitchin', if you need any help with this i'll be glad to
lend you a hand in what I can.
OSS sucks...sound quality is soooo bad!

Same for Suse 9.1 / Kernel 2.6
After restart sound randomly works with crackles or not at all.
Tried every workaround found on the web, none works. Driver must be broken
for this particular notebook. Any news for this bug since it is known for
a long time?
