Comment 1 for bug 441746

P.S. I've tried changing the "profile" under the "Hardware" tab of my one audio device to everything available, and none of it gives me sound. Basically anything with "digital output" should be working.

Also to further make things interesting, at first I had done an upgrade from Jackalope, where I had already unmuted the digital output, to Koala, and everything was working. It wasn't until I did a fresh install of Koala that this issue popped up.
