since kernel 3.1 playing sound through HDMI via pulseaudio stopped
working after suspend/resume on my Intel HDA (there is simply silence
after resume). Same for 3.2. This worked up to 3.0 and it still works
when I configure pulseaudio to play through Analog Stereo instead of
HDMI, hence I guess the issue is more connected to ALSA than to

A work-around is to induce pulseaudio to re-open the underlying audio
devices (`pasuspender true' does the trick).

Here is the alsa-info.sh output for kernels 3.0 and 3.1 (no significant
changes afaics):

Please let me know if I can provide further information.

Thanks for your work & best regards
