Patch applied cleanly to r230008 using `svn patch`.

pcm4 (builtin speakers) and pcm5 (headphones) seem to work fine, however
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.


Thanks,
Yuri
