Which? None. No outputs are audible, so far as I can tell. The
'pavucontrol' streams still work, the meter goes up and down to the
silent music.
On the good kernel (3.1.0-1) sound plays through the (separately
powered) speakers plugged into the back of the PC case; when I plug the
headphones in a different jack on the front of the case, the speakers
turn off, and the headphone sound goes on.
On the silent kernel (3.2.0-1), there's no sound from headphones or
speaker, and the headphones being plugged and unplugged has no audible
effect on either speakers or headphones.

On the good kernel (3.1.0-1), this happens:
% amixer -c0 set "Auto-Mute Mode" Disabled ; echo $?
amixer: Unable to find simple control 'Auto-Mute Mode',0
1
Haven't tried that 'amixer' command on the silent kernel (3.2.0-1).
