White Noise

Hey, I am getting alot fuzz in my playback and I can't seem to eliminate it. What is the best way to reduce white noise. Thanks

It is like a hiss sound that occus when the tracks begin. Can you tell me which plugins would best solve my problem? I appreciate any advice you could give.

You might also want to post specific info about your system - computer model, processor, chipset, the Digidesign hardware you're using, etc. as this may be something system specific.
