Public bug reported: After a dist-upgrade a few days ago (12.04) I was not able to hear sound any more. No error messages, everything seemed to work fine - simply no output.
Removing the package speech-dispatcher solved the problem (it had running pulseaudio processes, too), however that is a workaround. What you see in the debug information is the situation after removal of the package speech-dispatcher.
