Look out for cards that claim they are "Soundblaster Compitable" many are,
but NOT at 44.1 kHz, 16 bit, Stereo..
"Soundblaster Compitable" Marketdroid invented term ? :-)

Buffering is done with primary memory. Card only needs about 4K buffer.

I think your problem is IDE, I have seen this problem several times. As soon
an IDE unit is used in the system. mp3 playing becomes a lot easier
disturbed task.
Advise .. use SCSI ONLY. Ofcourse it's a question of money too.. ;)
If you really must use IDE, throw them to another computer which runs as a
NFS server.
