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.

M.
