VIA 82C686 AC97 sound in RH9 problems

zapp · 08-24-2003, 03:45 PM

Greetings one and everyone,

I just installed Redhat9, changing over from Slackware 9. Overall I am quite impressed with how much things "just work" (as opposed to the DIY way of slackware).

However, there is one thing that I just can't seem to get working... my onboard sound card.

The motherboard is an AOpen AK33, and has a VIA 82C686 on board sound card. Redhat detects it and loads the following (relevant) kernel modules

Code:

[root@localhost root]# lsmod
Module                  Size  Used by    Not tainted
via82cxxx_audio        24088   1
uart401                 8260   0  [via82cxxx_audio]
ac97_codec             13544   0  [via82cxxx_audio]
sound                  73108   0  [via82cxxx_audio uart401]
soundcore               6276   4  [via82cxxx_audio sound]

and whenever I try to play back sound I get the following:

Code:

Aug 24 14:31:35 localhost kernel: Via 686a/8233/8235 audio driver 1.9.1-ac2
Aug 24 14:31:35 localhost kernel: PCI: Found IRQ 9 for device 00:07.5

Aug 24 14:31:35 localhost kernel: via82cxxx: timeout while reading AC97 codec (0x1FE0000)

I tried setting up ALSA, but didn't quite get it right.

Anyone know if this is a supported soundcard, and if it is why can't I get it to work? I think it is supported, as there is a 82cxxx module, and it's listed here

Thanks in advance!

try upgrading your kernel. i'm using the same driver back home and the upgraded kernel works fine. The shipped kernel also works but had some noise in the background.

also, consult your mobo manual. it might have some addtnl config settings for your sound card.

thanks for the reply

I will definitelly concider your suggestions, but I'm starting to suspect that that functionality on the board is just dead (realized that back when I ran Windows on that motherboard, it always bluescreened when onboard sound was enabled... )

That is the correct module. I am running Mandrake 9.1 with the 2.4.21kernel and my sound works great.
