--- Comment #17 from Martin Jürgens martin@gamesplace.info 2008-06-10 16:50:37 --- I don't have time to test it this evening. Sorry, later!
What I noticed, though, is that Rayman and other games play sound even when PulseAudio is running. (I do not know what the behavior was before, I think that it didn't do anything).
When I listen to music using Rhythmbox and then start a game though, sound is not working. Another thing I found weird is that Wine or the game is not displayed in pavucontrol as a sink, which could be related.
