Same problem hear after upgrading to Intrepid: I can hear the login sound but, after that, Totem is unable to play any movie or sound and I get the "Failed to connect stream" error when I press the test button in the sound preferences panel.
If I change my sound preferences to alsa or oss the sound tests are OK and if I kill pulseaudio from a console and start it again with "pulseaudio &" everything start to work, but when I restart the problem appears again.
So, as a summary, I can hear the login sound and I get the sound working again if I kill and restart pulseaudio manually.
