>Description:
When playing a MP3 (I'm using XMMS under KDE) with a M-Audio Audiophile USB [USB sound card], switching to the console then to X again, the system crashes. The system does not crash when using another (non-USB) sound card instead (a CMI chip on the mainboard which does not appear on the logs because it has been disabled since that).
