[expert] Sound - How to fix if MP3 files play at slow speed and then makes noise after 10 seconds? CD sounds fine.

[Sevatio Octavio]

How do you fix this sound problem:  MP3 files play at slow speed and then makes noise 
after 10 seconds?  CDs sound good and MIDI
seems to work.  This is on a Compaq Presario Desktop with an ESS1888 soundcard.

Thanks,
Seve
