Playback skipping

I was using an onboard soundcard and changed to a Soundblaster PCI128 out of my old computer. Ever since I did this there are playback skips. It does not effect editing or anything else. Only playback. It also only happens haphazardly. No certain song or timing. Someone told me something to do in the BIOS before for this particular soundcard but I can’t find it since I built my new pc. I searched on here and came up with a DMA tweak and did what it said. My IDE channels were already set to ultra DMA.
