You can change that in the Preferences dialog. Maybe the error message is misleading and the audio device is blocked by some other sound application (KDE's artsd?) You could check out XMMS's settings (click on the little 'O' for the menu), see what output it uses. My guess is it uses arts or ALSA, see if it works with OSS. If it uses arts, you'd probably have to stop artsd. (You can disable it in KDE control center.) Eventually you wanna give jack a try. As mentioned before qjackctl is the way to go. It can also stop artsd automatically. cheers, Christian
