Messed up sound with Vista Home Premium-new iMac

[Durmortec]

So I installed Vista and everything works beautifully except for the fact that I can hear some feedback coming out of the speakers when sounds play, this is most evident when you're playing music or listening to a movie, it sounds like a weird whirring noise that is constant. I rebooted in OS X and don't have that problem so it's gotta have something to do with windows, any advice?

Make sure you have the latest driver versions for PC of the speakers. That's about all I can think of off hand.

Open up the mixer and disable the microphone in playback and record settings. Maybe the feedback is from the microphone being active and playing through the mixer or something.
