Public bug reported:
My fully working sound configuration occasionally stops working. Symptoms are:
- System Settings -> Sound only shows "dummy output" and no input devices
- restarting pulseaudio has no effect
- aplay -l as root shows sound cards
- fuser -v /dev/snd/* shows nothing; /dev/dsp and /dev/seq do not exist
- Rebooting solves the problem
This did not occur on trusty but has occurred twice on utopic in the
last month or two.
