Bug Description

I encountered this bug:
https://launchpad.net/distros/ubuntu/+source/linux-source-2.6.17/+bug/68659
Before commiting the fix posted there, I had the PCM channel visible in KMix and in ALSAMIXER, and it worked too, but after the fix (echo "options snd-via82xx dxs_support=2" |sudo tee -a /etc/modprobe.d/alsa-base) I had no PCM neither in KMix or in ALSAMIXER. This means I can't set the volume, and can't turn mute on. I can only adjust the volume through PCM, as I did in Breezy and Dapper... but I can't do it here in Edgy any more.

One more thing, can't get 5.1 to work either...
Tried setting it in Amarok, in Kaffeine... but nothing. It's set to 6 channels in alsamixer though... but as I said they have no effect over volume or things like these...

You need to try dxs_support=5 instead of dxs_support=2.
