Patch was generated for 10-CURRENT, but should apply to fresh 9-STABLE
and 8-STABLE branches also.
Patch applied cleanly to r230008 using `svn patch`.

pcm4 (builtin speakers) and pcm5 (headphones) seem to work fine, however
Thank you.
I'm not getting anything out of pcm0-pcm3 (connected to a TV via HDMI),
mplayer just pauses at the beggining, trying to cat anything to
/dev/dsp{0-3}.0 gives:
pcm0: chn_write(): pcm0:virtual:dsp0.vp0: play interrupt timeout, channel dead
It was the same with the old driver and I'm not sure if it's (most
likely) my misconfiguration or a driver problem.
It sounds more like a driver problem. HDMI audio is still not very well
discovered area, and, according to ALSA reading, NVidia HDMI is also not
very standard. Probably I'll finally have to buy something to
experiment. What card do you have?
