Hi Alan,

I have the same hardware and pulseaudio configuration as you. (I guess
it's quite stock standard).

I've had the odd occasion where I "loose" sound after using the
keyboard's shortcut key for mute.  A little one liner got it back:

amixer -D pulse set Master 1+ unmute

This assumes you're using alsa as the backend for pulseaudio.

Other possibilities are missing modules, kernel compiled with missing
options, missing packages for audio subsystem pulseaudio communicates
with.  It's hard to be specific without exact errors.

Hope that helps.
Carlos
