I recently updated to 11.04, and it seems rhythmbox broke for me in the update, as well as the new default, banshee. When I try to play a song, the play button changes to a pause button, but nothing plays and the scrollbar detailing the current time of the song doesn't move. It might be a problem with the streamer, but I'm not sure. Has this happened to anyone else?
I've found that it's not just them Banshee and Rhythmbox, no sound works. Also, it only stops working with Unity on -- it works fine with Ubuntu Classic.
