Audio driver problem with nForce 430 (AD1986A)

[Ka-Ka]

I have a Asus A8N-VM CSM board (with Nvidia nForce 430). According to the specs it have a "High Definition Audio, ADI AD1986A 5.1channel CODEC" device.

I have tried several ALSA drivers and the OSS driver supplied by Nvidia (media-sound/nforce-audio v1.0.0310) and havn't got it working

My question, have anyone else got it to work? What driver have you used?

[piranha2001]

I am using the hda_intel-Module from the kernel and I get a f**king beep on the one channel and sound on the other.
After some seconds or after adjusting the mixer this "mono"-sound stops.
I found a patch here:
http://www.ubuntu-forum.de/artikel/4610/Sound-mit-Amilo-Pro-2040--Intel-915GM.html
and applied it. Didn't help...
Anyone here who got sound on Asus A8N-VM CSM running?

Hopefully they will find a fix soon:

I read that there were people who got it running under different Linuxes, noone with Gentoo???



Thanks in advance,
Sebastian

Hey Ka-Ka, do you still have the sound-problem?
For me it works now. I used a patch I found in the Nvidia-Linux-forum and reinstalled ALSA again.
http://www.nvnews.net/vbulletin/showthread.php?t=57791&page=8&highlight=asus+a8n-vm
Look at KenWoodland's posting for the patch.
I compiled Kernel just with Soundsupport, no Alsa, no OSS and emerged alsa-utils without alsa-driver-package. (Or unmerge alsa-driver, if you have it on your syste.)

[Ka-Ka]

Thanks piranha2001! I will try out your solution soon.

Happy new year!

[Ka-Ka]

The sound works for me too with the workaround.
Thanks again piranha2001!

[piranha2001]

You're welcome.

I don't really remember as it was a while ago since I installed it, but is'nt you suppose to run alsaconf to detect your card automatically?

Anyway the modules that you are intrested in if you have a A8N-VM CSM are snd-hda-codec.ko and snd-hda-intel.ko

[ions]

Yeah, after I posted that I had tried running alsaconf. I went through the menu and it listed the nvidia driver and it finished with this:

[Ka-Ka]

I saw that there are new version of the alsa-driver. Have anyone tested it? Do it solve our problem. It would be good to get a less hacky fix for the problem.

media-sound/alsa-headers-1.0.11_rc2
media-sound/alsa-driver-1.0.11_rc2

The releasenotes for the changes between 1.0.10 and 1.0.11_rc2 can be found here:
http://www.alsa-project.org/changes/v1-0-10--v1-0-11rc1.txt
http://www.alsa-project.org/changes/v1-0-11rc1--v1-0-11rc2.txt

I found at least one line in the releasenotes that might indicate that our bug is fixed.

- Summary: hda-codec - Fix surrounds on 3stack mode of AD1988
Fixed the swapped surround/CLFE on 3stack mode of AD1988.

Have anyone tested the alsa-driver-1.0.11_rc2?

Oops forgot to mention my board: Gigabyte K8N51GMF-9. Same chipset so it would be the same module correct?

Hello ions!

Apparently I am not alone: http://www.nvnews.net/vbulletin/showthread.php?p=788831#post788831

Appears Udev is involved.

thanks alot for your postings!
My system crashed after updating to alsa-driver-1.0.10 during booting with an error message about:
module snd_mpu401 not found segmentation fault
pump - the system freezes ...

I removed alsasound from the rc-update (rc-update -d alsasound deault) - system freezes.

I removed coldplug (which I reemerged) from the rc-update (rc-update -d coldplug default) - the system boots correctly. After that, a
/etc/init.d/alsasound start
works without problems.

I think, coldplug recognizes a "mpu device" and tries to start the mpu-401 module - and than it bangs.

I downgraded to alsa-driver-1.0.10-rc3 - and everything works well again (with coldplug AND alsasound in the rc.update as default).

I use kernel: 2.6.14-gentoo-r5
The mainboard is a ASUS A7N8X (nvidia nforce2 chipset)

Note that I am using the amd64 platform, so some of these requires ACCEPT_KEYWORDS="~amd64".
Also, s/pink/orange/. Can't tell in this light.

Using 1.0.10_rc3 I get sound with "clicks" at around 30Hz. (Sounds like the interrupt handler is broken. Is this the "crackling" that needs modprobe snd_hda_intel position_fix=1 ??) Also, running alsamixer while aplay is playing messes up the mixer settings, everything gets muted (though alsamixer doesn't think this is so). The way to fix it is:

This is supposed to be fixed with ALSA 1.0.11rc4, but I am not having much luck.

Is anybody using Alsa 1.0.11rc4 and SPDIF to a AV Receiver that has 5.1 (or 6 channel) audio working?

[OlegVekhov]

Installed lastest ALSA drivers 1.0.12rc1 and have the same annoying clicks on playback.

I have Amilo Pro v2045.

There are an article in WiKi, but it's very old... The annoying high freq sound was eleminated after upgrading to 2.6.17.6 kernel, but clicking continues with both kernel and latest alsa drivers.

position_fix option has no effect for me

I've read through the bugs on bugtrack.alsa-project.org. tiwai (I think he's a moderator there) refers the three bugs to #1596, but correctly detecting the model is not the problem, and so the bug is not resolved. I have an Asus A8N-VM-CSM, and although the high-pitched noise sometimes disappears, it's definitely still there (sometimes).

The problem right now is that although snd_hda_intel correctly detects nForce 430 chips (on the motherboard) as a model=3stack (turn on CONFIG_SND_DEBUG and CONFIG_SND_DEBUG_DETECT, then the dmesg log has "ALSA sound/pci/hda/hda_codec.c:1827: hda_codec: model '3stack' is selected for config 10de:cb84 (ASUS A8N-VM)") but it doesn't work as a 3stack. It doesn't work in 6-channel mode.

That's why some users have reported success by adding 'options snd-hda-intel model=laptop' to /etc/modules.d/alsa (or modprobe.conf). It forces the AD1986A (inside the nForce 430) to operate in 2 channel mode.

Allowing it to correctly detect model=3stack results in the right mixer channels showing up in alsamixer: front, surround, lfe, and center. And I can even set the values as long as no sound is playing. But when I play something (I'm using mplayer) if I touch the mixer, everything gets muted, and I have to do a /etc/init.d/alsasound restart (which unloads and reloads the modules). While playing sound files, I often get the high pitched tone.

The channels are not mapped correctly, either. I may not have set up alsa correctly, but of the three audio outputs on the 3stack, I think the microphone is still configured as a microphone. I know that the other two are configured for output, because when I connect speakers to them, I get sound out of front right, surround left, and surround right. (Note that front left is either a high pitched tone or mute).

I suspect the problem is that the snd_hda_intel module is making incorrect configuration choices for the AD1986A. I'm going to poke around a bit, and see if I can figure out what's wrong.

As bug #2889 suggests, be sure to update your BIOS to at least version 1007. But that doesn't resolve the problem.

[dch24]

It's apparently also possible to freeze the system while unloading snd_hda_intel. (That is, it deadlocks while unloading. The system continues to run.)
