Something appears to be borked in the ALSA arena. There's no actual volume coming out of the system, and 'alsamixer' is insisting that the volume slider only goes from 0 to 10% or so, no further. However, experimentation shows that the volume slider in 'xine' *does* affect the 'Amp-Out vals' lines, and alsamixer has *no* effect on what 'Amp-Out vals' lists.
A diff of alsa-info.sh for the two kernels shows them being identical, so I'm only attaching one copy.
It may be the weekend before I find time to do a bisection of this.
Didn't you (like some other people) get into the state where pulseaudio doesn't work? It chooses as an output a dummy driver automatically, then you can change volume, play sound, but actually it all goes to /dev/null.
It took me a while before I figured out that it's a "dummy" driver I have in pulseaudio.
Looks like there is a breakage regarding open/close due to fs/notify/* changes. I guess you can hear still sounds like:
% aplay -Dplughw foo.wav
