I'm sorry I wasn't monitoring this thread, so excuse me if you've been
through this.  When I have sound problems with Ubuntu, it's always been
pulseaudio.  I kill it and restart it and I have sound again.

Oh, except once, for some reason a firefox video plugin dug its roots
into the sound system and wouldn't let anything else play until I
rebooted.  I found the culprit with lsof.
