    Specifically, XP. It has never done this before to my knowledge, and does so only from the built-in speakers. I checked it with a dB meter, and it was 93 dB, A weighted at about 3 feet. Yes, that is damn loud.

    The odd part: muting the software volume control makes it go away.

    AFAIK, it has never done this, and It has been used in boot camp a fair bit, though with the optical audio out more often than not - still a fair bit with the onboard speakers.

    This doesn't seem to be the same issue with the 2006 MBP's whining/squealing in boot camp, as far as I can tell.

    Anyone else experience anything like this? I'd rather not hook it up to external speakers while the possibility of damage-causing tones is still there.


    Edit: muting the mic playback seems to kill it..... why was that enabled (I sure as heck didn't do that!)

    Since muting it with software works, my first guess would be that your audio drivers have corrupted themselves. Try downloading the newest ones from Realtech's website.
