Netflix audio crackling

[Chaosmint]

Hi, I've been testing netflix on this computer, and it seems the audio is crackling no matter what video I watch. I have an iMac, and through testing I have confirmed that it must be my hackintosh, since my iMac doesn't stutter through any of the same exact content. What could this be an issue with? I don't have audio problems in iTunes, so I'm suspecting a problem with silverlight.

Suggestions?

UPDATE: Literally 20 seconds after posting this I tried closing Folding@Home to see if Netflix was running out of processing bandwidth, and now the audio is completely fine! So to anybody who is facing similar problems, here's a potential solution.

Have you checked if you have the latest version of Silverlight?

Also it wont hurt to check the sound output format

Thanks! I figured out why that was happening as well!
I was encoding movies using Handbrake and it was taking up all my CPU usage. Weird how that affects audio processing.
