Realtek ALC883 support on Albatron KI690-AM2 motherboard

Realtek ALC883 support on Albatron KI690-AM2 motherboard

[Andrew Paprocki]

Hello everyone,

I'm currently trying to get the ALC883 on the Albatron KI690-AM2
motherboard working under ALSA and I'm running into problems with some
of the ports. From looking at the patch_realtek.c file inside the
intel_hda driver, it appears there are many variants of hookups to
this chipset which all require some manual configuration in the
driver. I've tried what appears to be the closest match
(ALC883_6ST_DIG or 6stack-dig), but it still does not enable all of
the ports.

The motherboard webpage is here:
http://www.albatron.com.tw/English/product/mb/pro_detail.asp?rlink=Specification&no=239

The board has two audio stacks on the back panel. Facing the jack
inputs, the left-hand stack contains:
    <S/PDIF output>
    <TOSLINK w/ green cover>

Next to that stack is a larger 6-stack with the following configuration:
    <blue> <black>
    <green> <pink>
    <grey> <TOSLINK w/ pink cover>

The box is running a stock debian 2.6.18-4-486 kernel. The kernel
outputs this at startup if the "6stack-dig" model is not explicitly
supplied:

    hda_codec: Unknown model for ALC883, trying auto-probe from BIOS...
    hda-intel: Invalid position buffer, using LPIB read method instead.

When using the "6stack-dig" mode, ALSA sees two devices:

    card 0: SB [HDA ATI SB], device 0: ALC883 Analog [ALC883 Analog]
      Subdevices: 1/1
      Subdevice #0: subdevice #0
    card 0: SB [HDA ATI SB], device 2: ALC883 Digital [ALC883 Digital]
      Subdevices: 1/1
      Subdevice #0: subdevice #0

When attempting to use ALSA to open the first device in raw mode to
output to each stereo pair separately, 5 pairs are detected, and the
outputs appear as follows...

    Pair 1: <green> (working)
    Pair 2: <pink> (working)
    Pair 3: <black> (working)
    Pair 4: (no audio)
    Pair 5: (no audio)

No sound can be heard from the blue or grey jacks in any
configuration. I'm wondering if a special entry is needed in
patch_realtek.c to handle this board's usage of the ALC883. I am
willing to try changing the code and testing if someone can point me
to what might need to be done.

First of all, try the very latest ALSA version (from HG repo) if you
want to debug HD-audio stuff.  It's the most actively changed part in
ALSA drivers.  2.6.18 is way too old as a reference.  Also you should
build the driver with debug option (in the case of alsa-driver tree,
pass --with-debug=full to configure).

If the latest version still doesn't work (with all available models), 
then check /proc/asound/card0/codec#* files.

(Anyway, I'll be on vacation from tomorrow, so cannot work on your
 problem.  Hopefully this will interest other guys...)

Takashi,

Thanks, I'll work on getting this upgraded and post results. Some
things I noticed while looking over patch-realtek.c:

1) There is no enum defining the different NID values. The hex values
are used all over the code and you always have to keep referring back
to the list. Would a patch be accepted to convert the hex values to a
proper enum? It makes the code more clear to someone who hasn't looked
at the chipset datasheet before. I see the complete list in the ALC883
datasheet, but I'm not sure if it is specific to the ALC883 or if it
is defined by each HDA spec revision.

2) There does not appear to be an ALC883 profile which sets all
available NIDs to output. In my case, I am attempting to get as many
stereo outputs as possible from the chipset and I do not care at all
about capturing audio. The 6stack profile does not set the pin
configurations for the MIC1/2 and LINE1/2 NIDs. Would a new model be
required if I want to attempt to configure all possible NIDs for
output? Should this be called "all-out"?

3) I noticed a few discrepancies with the hda header files and the
ALC883 documentation in regards to bits being checked for a few
values. I'll follow up with those once I'm back in front of the code.

Takashi,

Running with the hg alsa head with full debug, I see the following
output.. The 01:05.2 device is an ATI HDMI port. I appear to have a
card0 after this which is the ALC883 chip. Do you know why the HDMI
port is not correctly detected as an "ATI RS600 HDMI" according to the
patch_atihdmi.c file? Do I need to pass any parameters to the module?

Thanks,
-Andrew

Oh, that's an unexpected problem.

Right now, snd-hda-intel driver is designed for a single device.
I wrote it so because I thought the device is only for on-board.
But now, ATI ships the graphic card with the extra sound
controller, and this conflicts.

So, we need a major change in the driver code to allow multiple
devices.  OK, I'll hack it so that it can go to 2.6.25 kernel...


Meanwhile, did you try any model option for ALC883 (check
ALSA-Configuration.txt for the available values)?  If none of them
matches well, we'd need to develop a new model.


thanks,

Takashi

The below is a quick hack to support multiple cards.

Could you give it a try?

Re: Realtek ALC883 support on Albatron KI690-AM2 motherboard

[Andrew Paprocki]

Takashi,

I finally got the hardware set up again to test the patch. I noticed
that it was already applied to hg, so I just used the latest hg code
to test. With the new code the 2nd device was always failing with an
-EBUSY error. I poked around adding some printk's and noticed that the
device count wasn't being incremented for subsequent cards. I fixed it
and submitted the patch. With that modification it appears to be
working now:

$ modprobe snd_hda_intel
ACPI: PCI Interrupt 0000:00:14.2[A] -> GSI 16 (level, low) -> IRQ 16
hda_codec: Unknown model for ALC883, trying auto-probe from BIOS...
ACPI: PCI Interrupt 0000:01:05.2[B] -> GSI 19 (level, low) -> IRQ 18
