DMA by a SCSI card is a completely different thing than DMA with a soundcard. A soundcard requires every byte right in time or otherwise an underrun occurs. DMA with a SCSI card doesn't have this kind of requirements.
It's very possible that some SCSI activity during sound playback causes your problem. This is the case at least if you use a PAS16 soundcard together with an AHA1542 SCSI controller.
