This is somewhat expected behaviour. Access to the audio device
follows the active session on the display. I.e. if you switch VTs than
ConsoleKit+HAL will change the ACLs of the audio devices and tell PA
to stop accessing the audio device. This will cause playback to pause
for all applications accessing PA. However, as soon as you switch back
the session, the playback should continue. This is not perfect
however, since we don't inform Gst/Rhyhtmbox that the audio device is
temporarily stopped (there's no way to do that afaik).
