I don't know of this issue, so need to check more.
Could you load snd-hda-intel module with probe_only=1 option, and run
alsa-info.sh with --no-upload option and give the output?
Then I can try the emulator to see what's wrong.

Also, of course, testing a newer kernel like 3.5-rc7 would be helpful,
too.
