Firstly, I don't have the same board. Similar, but different.
I have an Asus A8N-VM CSM board, but it has the same AD1986A chip on it. I didn't have the same issue with sound muting, but I did have issues with surround (it just didn't work). I don't remember the details of how

thanks for your try. it helped partly ... I tried 3 patches (incl. yours) and only yours helped partly at least. I patched Alsa 1.0.15rc3.
Sound mutes as soon as I change volume, and I can only rmmod/modprobe snd-hda-intel to get it back.
But Surround is working with your patch as I can see: "speaker-test -Dplug:surround51 -c6 -t waw" recognizes correctly all speakears.
"speaker-test -c6 -t waw" does not recognize the speakers correctly, but it probably should not, or ?!
MythTv is playing stereo files only on the right speakers. I do not now is this a MythTv or Alsa problem. probably MythTv and I should create a .asoundrc which should correct this somehow.
I did not try hg, because I thought that Alsa 1.0.15rc3 is very new.
Thanks.
