Comment 9 for bug 176110

I looked around some more and found http://bugzilla.kernel.org/show_bug.cgi?id=7467
It looks a lot like my problem.

So I unloded snd-atiixp and reloaded it with ac97_codec=0. And it works!

I created a file /etc/modprobe.d/atiixp with the content:
options snd-atiixp ac97_codec=0

and now it works between reboots :)

All this was done in 7.10.

A quirk should probably be added to snd-atiixp the same way as for DFI rs482
