[GTALUG] Ubuntu Studio: Sound not working in all applications

[Russell Reiter]

This may be a known bug.

You say alsa is not running. However I believe the sound daemon is
either Alsa or OSS, although OSS seems to have been eclipsed by Alsa.
Try this in order to unmute everything.

amixer -D pulse set Master 1+ toggle

Or you could try installing pavucontrol.
