We upgraded lwjgl from 1.4 to 2.0.1 in the most recent update for our game. Since the update, I've gotten several reports of sound being choppy and stuttering. I've also gotten a few reports of CPU usage spiking dramatically when sound is played, but there aren't as many reports of that as there are of stuttering. Thus far I've only gotten reports on Windows, but it runs the gamut from 2000 to XP to Vista, and has come from different revisions of Java 1.5 and 1.6. Our bug reporting tool doesn't include sound card information, but I've gotten dxdiag dumps from a few players, and haven't seen any particular sound card or driver shared between them.
This definitely isn't happening in the majority of cases, and I can't get it to happen on any of the Windows machines I have access to. Is there some further lwjgl logging I could add to the bug reports that might shed some light on why it's happening in some cases? Is there anything I need to do differently in the 2.0 series to hook lwjgl and openal libraries into Java or to set up the sound system?
