Before you log out and back in, fire up a terminal and check to see if pulseaudio is still running. If it quits, your audio goes away.
Assuming your login name is part of the "pulse-rt" group (if not, put it in there), you can try to restart pulse by doing:
pulseaudio --start
as the desktop user...NOT root. See if your sound is back.
Rick,
Sorry for the delay in replying to your helpful message. At one point, audio seemed to be working again. Right now, however, no sound. Earlier this afternoon, banshee was playing OK, but for some reason audio simply stopped working.
I tried exiting pulseaudio and restarting as you indicated. It appears to be active. I can open Sound Preferences and see the apps that are using sound, ie, Rhythmbox and/or Banshee and/or VLC. The programs themselves appear to see the audio device and play without any error message.
I am quite sure it is not an inadvertently selected 'mute' box ;)
At this point, I am clueless. I have no idea what is crashing nor why. I can't identify any kind of reproduceable pattern.
Any thoughts?
Thanks.
