Comment 15 for bug 449783

I had the same problem, but when I tried adding 'load-module module-volume-restore' my problems got worse. Now I have no audio and I can't run pavucontrol. The window pops up, then it gives error message 'Connection failed: Connection Refused'. I can open the xfce alsa mixer, unmute and change levels, but it mutes as soon as I try to feed it audio.

I tried undoing the change I made to 'default.pa', but it didn't make any difference. I also tried reinstalling all the pulse audio packages I had installed in synaptic, so it seems like there's a rotten config file somewhere.

I should also mention that I installed pulse audio while running the generic kernel, but booted into the realtime kernel afterwards. I didn't experience any problems after this except for everything being muted. pavucontrol worked fine and I had sound. It wasn't until I tried the fix mentioned above that everything went out.
