Comment 6 for bug 320798

That doesn't do it for me. After running it, I still have no sound (and no pulseadio process running). If I try to run pulseaudo after killing it, then:

$ pulseaudio -k

Adding myself to the pulse-rt group did not appear to make any difference. Still no audio under Jaunty anymore.
