Sound doesn't work on A8V-MX (VIA8233)

Bug Description

A8V-MX motherboard with built-in sound (VIA8233 IIRC)

Ubuntu Edgy

Although driver all appears to be loaded and present, no sound is ever played. Speakers work fine on another machine.

I have also compiled latest alsa1.0.14 per alsa instructions for VIA82XX(*) - still no sound. Incidentally, following alsa instructions for ~/.asoundrc results in no soundcard being recognised at all in System>preferences>sound. Deleting ~/.asoundrc gives VIA8251 only, but still no sound.

(*) http://www.alsa-project.org/alsa-doc/doc-php/template.php?company=VIA&card=VIA+southbridge+AC97+audio.&chip=VIA82C686%2C+VIA8233%2C+VIA8233A%2C+VIA8235%2C+VIA8237&module=via82xx

Thanks for looking at this. I've spent two days without getting any where and I've run out of ideas.

I've checked permission and that users are members of audio group

# ls -ls /dev/dsp

# ls -ls /dev/mixer

# cat /etc/group |grep audio
audio:x:29:patrick,mythtv

And I've passed the following flags at boot, without any improvement (although nosmp had a pretty negative effect!)

noacpi
nolapic
nosmp
noirqdebug
pci=conf1

I've also tried this, although I'm not sure what the error tells me.

After a week of googling, I'm still no further forward on this and I haven't found ant evidence of anyone getting sound working with this motherboard on Linux.

However, I have discovered that it is actually playing sounds, just very, very quietly. With everything turned up high, and ear pressed to speaker, you can just hear the sounds (speakers and amplifier test out fine with a pci soundcard in the same machine). Does this shed any light to anybody ... help!

After finally giving in and installing Windows, I discovered that this was caused by a motherboard fault. The fault is now cleared and sound works correctly (Hooray!).

So thanks for looking, and sorry for wasting anyone's time.
