Sadly I'm not offering help here.

I have probably a related problem. Using the same driver on a K7VT2 MB 
and the linux-2.6.0-test11 kernel.

Using XMMS version 1.2.8 with the libOSS.so driver I get a garble/speed 
up at exactly 19 seconds which last perhaps 2-3 seconds.

Using XMMS with the libALSA.so driver. I get persistent clicks 
through-out the MP3 track.

Anyone else got an idea of this is caused by?
