Problem: Rhythmbox play no sound after changing output device. Ubuntu 12.04, i386, Rhythmbox 2.96.

How i get this:

 - I have connected to my laptop a bluetooth headset.

 - In sound preferences I changed output device from notebook speakers to connected headset.



 - Turned on rhythmbox to listen to music.

 - Gave my headset to my friend without turning off. 

 - Laptop turned off.

 - Laptop turned on.

 - I tried to listen to music with rhythmbox.

Rhythmbox behavior is as usual, but applet-indicator on drop-down sound menu freeze when i click to play If to start rhythmbox from dash it works but no sound is playing. Other players works fine. I tried purge
rhythmbox, gstreamer* and install it again, but no luck. If to login
in other user - rhythmbox works fine.

I think it is something with pulseaudio, but i don't know what to do...
