I had this bug and found several configuration problems. One of which was timidity stealing the sound card, as described here: <a href="https://wiki.ubuntu.com/DebuggingSoundProblems/KarmicCaveats#Another%20process%20locking%20the%20sound%20card">Process locking sound card</a> The described solution did not work, so I uninstalled timidity-deamon and the problem went away. Further problems were caused by me selecting the incorrect sound card, I meant to use an integrated one, not the Ensoniq.
