no sound with VIA VTX82xx onboard sound card

[hyperpsyched]

So I have surfed and googled and have found no real solution for my problem... no sound at all. No system test sound... nothing.

For those who read the post here is some info:

rtichy@edison:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: VT82xx [HDA VIA VT82xx], device 0: HDA Generic [HDA Generic]
Subdevices: 1/1
Subdevice #0: subdevice #0

rtichy@edison:~$ lspci -v

***lots of output***

0000:04:01.0 0403: VIA Technologies, Inc. VIA High Definition Audio Controller (rev 10)
Subsystem: Micro-Star International Co., Ltd.: Unknown device 7255
Flags: bus master, fast devsel, latency 0, IRQ 58
Memory at dfafc000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <available only to root>

While I am not 100% sure what the above is telling me I think I can assume this means that the card is recognized... so why am I not getting any sound. I assume that the right drivers are loaded but I am not sure.

Any help would be appreciated.

Ciao, hyper

I am having the same issue, and can not find any help anywhere that has worked. I tried everything at the Comprehensive Sound Problems Solution guide at http://ubuntuforums.org/showthread.php?t=205449 and nothing has worked. I have VIA 82xx onboard sound and am running Feisty.

under KInfocenter>sound this is what I get

and my lspci -v

I am new to Linux, and would love to get my sound going. If anyone has any advice or a good post to check out that may guide me in the right direction, please let me know.


thanks in advance,

Just a real wild guess from me...

modinfo snd_via82xx gives

Maybe loading the module with ac97_quirk options might be worth a try since

You can use the 'ac97_quirk'-option if your volume-level is very low (probably
due to some switching of the headphone and master controls). The options:
ac97_quirk - AC'97 workaround for strange hardware (-1 = default)
-1 = default, don't override
0 = disable
1 = use headphone control as master
2 = swap headphone and master controls
3 = for AD1985 turn on OMS bit and use headphone

Try unloading the module and reloading it with one of the options...

rmmod snd_via82xx
modprobe snd_via82xx ac97_quirk=<0,1,2,3>
