(This message references ALSA bugtracking issue ID 2655.
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2655)
I am researching issues I am having with the audio chipsets onboard my
ASUS A8S-X Motherboard, which has an AD1986A CODEC, using its AC'97
interface.
$ cat /proc/asound/cards
0 [SI7012 ]: ICH - SiS SI7012
SiS SI7012 with AD1986 at 0x8000, irq 50
The attached patch file removes the "V_REFOUT Enable" mixer control that
recently was added to the driver for the AD1888 CODEC, and was inherited
by the driver for the AD1985 CODEC. The AD1986/AD1986A CODECs currently
utilize the AD1985 driver.
I am preparing additional patches that will provide improved support for
these CODECs. Please let me know if my work thus far is satisfactory.

Summary: remove malfunctioning mixer control for AD1985/AD1986
This patch removes the "V_REFOUT Enable" mixer control for the
AD1985 and AD1986 CODECs.
Previous patch "AD1888 mixer controls for DC mode" added
controls that were propogated to multiple codecs. For the
AD1985 codec, the bits VREFH and VREFD function differently,
preventing the "V_REFOUT Enable" control from setting V_REFOUT
to Hi-Z. For the AD1986 codec, the V_REFOUT pins are controlled
by other register bits.

Attached please find my revision 2 patch of improvements to the AD1985
CODEC driver. This supersedes the patch I submitted on 30-Nov-2006, and
patches the latest Mercurial source.
At this time I am figuring that I may be able to reduce the amount of
work I create for the ALSA-Project team if I combine my work into a
smaller number of patches. This combined patch includes all of the
modifications I have planned for the AD1985 CODEC driver. I am
continuing work on a patch to create separate AD1986/AD1986A CODEC
driver code.
In this revised, combined patch I have included my "fix microphone and
line_in selection logic" patch that should help users of the AD1985,
along with many other multichannel CODECs. I have also decided to
provide an enhanced V_REFOUT control, rather than simply remove the
faulty control, as I had done in my previous revision.
Again, any feedback regarding my work is welcome.

and the Surround jack is used for output, and in "6ch" mode

Attached please find my latest patch of AC '97 CODEC improvements. This
supersedes the patches I submitted on 30-Nov-2006 and 4-Dec-2006.
I am including my enhancements for the AD1985 and the AD1986/AD1986A
CODECs in a single patch due to interdependencies.
Notes:
- I have tested AD1985 functionality to the extent possible (mostly by
diffing register outputs).
- I have tested nearly all AD1986 functionality, except:
- My hardware is not equipped to test the Jack Sense mixer controls.
- I do not have any convenient method of testing the S/PDIF output at
this time.
- I made no effort to resolve anticipated Power Management issues.
- I noticed that the first time I booted with these new drivers
installed, the front speaker balance was off. Moving the Master
Surround slider all the way down and then back resolved the issue.

Summary: fix malfunctioning mixer controls for AD1985
This patch replaces the "V_REFOUT Enable" mixer switch control
with a listbox control for the AD1985 CODEC.
Previous patch "AD1888 mixer controls for DC mode" added
controls that were propogated to multiple codecs. For the
AD1985 codec, the bits VREFH and VREFD function differently,
preventing the "V_REFOUT Enable" control from setting V_REFOUT
to Hi-Z.
This patch also corrects an issue in which register bits relating
to mixer controls "Surround Jack Mode" and "Channel Mode".
The register bits controlled by these controls were being set
at boot time to states inconsistent with the stored values of
these controls.

Summary: fix various issues with AD1986/AD1986A support
Previously, ac97_codec.c was coded to support AD1986 and AD1986A
CODECs using code written for the AD1985 CODEC. This allowed the
LINE_OUT and HEADPHONE jacks to function properly, however register
differences between the CODECs prevented line and microphone inputs
from functioning.
Specifically, this patch fixes issues with the following mixer
controls: 'V_REFOUT', 'Spread Front to Surround and Center/LFE',
'Exchange Front/Surround', 'Surround Jack Mode', and 'Channel Mode'.
This patch removes the undocumented AD1888 control
'High Pass Filter Enable' and adds the new control
'Exchange Mic/Line In'.

Hi,
thanks for the patch.
For the ease of review, could you split your change to several
patches? Please post one patch per mail, then.
Anyway, a quick review through the patch is below.

This hunk likely breaks other codec support.
is_shared_linein() returns true if the line-in jack is shared with
surround output _and_ being used as the surround output. Maybe the AD
codec support is wrongly implemented.

This sounds fine, too.

These don't have to be defined in the public header.
(I'd rather like to move all these codec-speicific definitions to
local file, i.e. ac97_patch.c or local headers.)

Any need to be unsigned short?

Dangerous changes as I mentioned.

This rename would break many other boards since the renaming of
master/headphone is usually done via ac97_quirk.

Ditto.

Ah yes, the names are confusing.

Then change looks fine. One minor request is not to put a space
between '!' and the rest in the new codes. I used this style, but
apparently it's no major and kernel people tend to dislike it.
[BTW, I added Cc to alsa-devel ML again, supposing that you forgot
it.]

Summary: fix microphone and line_in selection logic
This patch fixes the Microphone and LINE_IN select logic for
Analog Devices surround codecs with shared jacks. The existing
code can never utilize the shared jacks for Microphone and LINE_IN
due to the reversed jack selection logic. The patched code
correctly selects the shared jack for input if the "Channel Mode"
selector does not specify that the jack is to be used for output.
Specifically, in "2ch" mode the Center/LFE jack is used for
microphone input and the Surround jack is used for LINE_IN,
in "4ch" mode the Center/LFE jack is used for microphone input
and the Surround jack is used for output, and in "6ch" mode
both jacks are used for output.

I noticed in reviewing support for other chipsets in ac97_patch.c, I
found samples of code that sets V_REFOUT to High-Z when the
corresponding jack is not currently configured for microphone input.
Is this something I should be doing? I'm not sure I understand how
V_REFOUT is used. Is it physically connected to the microphone jack?
Part of my confusion is that on the AD1986/AD1986A, there is a separate
V_REFOUT pin for each jack that allows connection to microphone(s), but
on the AD1985 there are 2 possible microphone jacks and 1 V_REFOUT pin.

I realize that the above macros don't need to be defined in
ac97_codec.h, however I figured the best place for my new macros was
alongside related macros, which unfortunately are located here. My
minimal change philosophy overrode any temptation to move the existing 6
AC97_AD_* macros to another location. If I moved those 6 macros, then
I'd also want to move the similar macros defined for other chipsets.
Additionally, there is the quandary that although it may be possible to
move some of the other macros to ac97_patch.c, (at least some of) the AD
macros would need to go into ac97_patch.h, since ac97_codec.c
(inappropriately?) contains some AD-specific code that references these
macros.
Here are the choices I see:
1) Add the new macros to ac97_codec.h
2) Leave ac97_codec.h untouched and add the new macros to ac97_patch.c
3) Move the above macros (ac97_codec.h lines 281-287) and add the new
macros to ac97_patch.h
4) Move all related macros (ac97_codec.h lines 268-363) and add the new
macros to ac97_patch.h
etc.
Thoughts?

I used unsigned short because it made the union an even 32 bytes. There
is no reason it cannot be an unsigned char.
(I'm tempted to add an extra byte of filler. Thoughts?)

Actually this maintains existing functionality, as patch_ad1985_specific
currently calls patch_ad1980_specific, which calls
patch_ad1888_specific, which renames the controls. If you'd like I can
change the functionality.

Ditto for me too, although here I left out the "Headphone" rename
because chipset differences suggest to me that there would be no use in
wiring the headphone pins as Line Out on the AD1986/AD1986A, unlike the
other chipsets.

Takashi,
Attached please find the second installment of separated patches you
requested.
I decided to submit this patch before receiving your response to my
questions because only one of the questions pertained to this patch (the
question regarding the renaming of volume controls), and I have come to
the conclusion that this patch should maintain existing functionality
regarding the volume controls.
My reasoning for this is that the mixer controls for the Analog Devices
surround CODECs appear to have multiple problems that justify a separate
project, time permitting. I'd rather focus this patch on the work I've
done so far, and save these other enhancements for another time.

Summary: fix microphone and line_in selection logic
This patch fixes the Microphone and LINE_IN select logic for
surround codecs with shared jacks. This issue appears to apply
to most, if not all AC'97 surround codecs. The existing code
can never utilize the shared jacks for Microphone and LINE_IN
due to the reversed jack selection logic. The patched code
correctly selects the shared jack for input if the "Channel Mode"
selector does not specify that the jack is to be used for output.
Specifically, in "2ch" mode the Center/LFE jack is used for
microphone input and the Surround jack is used for LINE_IN,
in "4ch" mode the Center/LFE jack is used for microphone input
and the Surround jack is used for output, and in "6ch" mode
both jacks are used for output.

AFAIK, such VREF changes are needed to reduce the possible noises on
the surround output jacks. It's highly depending on the board
implementation. So, if the driver works fine without vref change, it
should be OK :)

I'd like 2. Let's make a working version first, then clean up these
things, e.g. by moving codec-specific defines to ac97_local.h.
There are also defines in ac97_patch.c, and could be better placed in
ac97_local.h.

Compilers would care such a thing, so you don't have to worry much, I
guess. I don't mind so much what type is there, though.

Summary: fix malfunctioning mixer controls for AD1985
This patch replaces the "V_REFOUT Enable" mixer switch control
with a listbox control for the AD1985 CODEC.
Previous patch "AD1888 mixer controls for DC mode" added
controls that were propogated to multiple codecs. For the
AD1985 codec, the bits VREFH and VREFD function differently,
preventing the "V_REFOUT Enable" control from setting V_REFOUT
to Hi-Z.
This patch also corrects an issue in which register bits relating
to mixer controls "Surround Jack Mode" and "Channel Mode".
The register bits controlled by these controls were being set
at boot time to states inconsistent with the stored values of
these controls.
