xmms echo??

Hi, Finally I've managed to record mosic and to burn audio CDs. Playing the files and the CDs in any program which is able to do this is good. But in xmms it seems like an echo is added, like a second after the original sound. A kind of "shadow". This appears only in my on made files (audacity) and burnt CDs. Not with commersial ones. Funny, 'cause in every other play back program it's normal, and the CDs are normal in my stereo device as well. Has anybody experienced this, and why is it so? Regards, Thomas
