I've found a solution: edit /etc/group Code: Code: sudo vi /etc/group Next, search for audio, you shoud find somethink like this: Code: Code: audio:x:29:pulse Add a coma and your username afther pulse Code: Code: audio:x:29:pulse,username change username with yours Save and restart ubuntu, it should work. If I switch between sessions, I loose sound, but that is minor trouble. I hope this helps someone
