Hi,
I'm using snd-via82xx on an Ubuntu 8.04 system. alsa-info.sh output is here:

Here are the symptoms:
Audio goes away after a semi-random interval. Sometimes it returns after `modprobe -r snd-via82xx' followed by `modprobe snd-via82xx', but sometimes it seems to take a full reboot.
This looks similar to:

Some folks think that this kind of issue is triggered by audio volume being above a certain level. I'm not entirely sure if this is true, but I think it is. One time, I apparently triggered the issue by unplugging and replugging the audio cable from the mainboard during playback.
Audio can be heard even when the PCM volume level is 0 (as told by alsamixer). The volume does get louder when I turn up that mixer control, but it never goes away entirely when I turn the volume to zero. Mute works as expected.
This issue is impacting a significant project for me and my company. I'm willing to spend as much time as it takes to debug, and I'm fairly technical. I can also offer a bounty of some sort, if that interests anyone.
Can anyone offer any input?
