Mike: I tried PulseAudio:Default That and NULL are the only non-ALSA
devices that I'm offered. Results seemed unpredictable, usually loud
white-ish noise but with occasionally tolerable sections. I had a lot
of problems with sound earlier. Using ALSA:front:CARD=Intel,DEV=0
hasn't given significant problems recently - except perhaps for this
bug. A similar bug has been reproduced elsewhere on f16 and is being
worked on. On my system this bug is no longer troublesome. The
'undefined sound file' was probably a Fedora upgrade artefact that was,
AFAIK, properly reset as soon as I tried making changes to the
Notification settings. I don't think I have more to add to the process
at this stage. Sorry :-)
But I do have another question that I'll send off shortly...
