Public bug reported:

Binary package hint: pulseaudio

I’ve just upgraded to Ubuntu 10.10, and was left with no audio.  I
fiddled with the audio settings a bit, and suddenly the audio started
working, but in a garbled way.

The following command, however, works perfectly.

speaker-test -c2 -l1 -twav -Dplug:front
