Playback does not work (and MuseScore prevents computer from playing sounds in other programs)

When I hit the play button, nothing happens. If I hit space (which according to the manual ought to start playback) I go back into note entry mode, even when note entry mode was turned off.
If I go to Display > Play Panel, I can check the checkbox, but no Play Panel comes up. All other panels work.

I tested the sound using Rhythmbox (mp3 player). If MuseScore is open and I try to play something on Rhythmbox, nothing happens. If I close the MuseScore window, the song starts to play in Rhythmbox. If Rhythmbox is playing and I start MuseScore, Rhythmbox stops playing.

Ubuntu 9.10 (Karmic Koala) running on an IBM Thinkpad T60
