Public bug reported:
Pulseaudio in Jaunty (0.9.14-0ubuntu10) isn't loading module-alsa-sink:
$ pulseaudio

Works fine with module-oss.
Also, the problem seems to have appeared out of nowhere - Pulse had been
playing fine, presumably via alsa, until it randomly started consuming
100% cpu and needed a kill -9. I've done this and restarted pulse many
times, but one time it just started throwing the error. Logging out and
rebooting haven't had an effect.
