Hi. I have an E-mu 1212m PCI-express going into a quadcore PC, windows 7. This PC is optimized for audio. Lately I've been experiencing small crackles that happen when the screen is working. I guess it's an IRQ conflict with the video card (Radeon 5750). Problem is, I can't seem to assign another IRQ to the soundcard to try this out. Can anyone help? Thanks! Daan
