Okay I have had this problem since the time I got my iMac. As for background, I am using a 24" Intel iMac. I have the Realtek audio drivers updated, am using boot camp 3.1, and am using Windows XP SP 3. I havent used my windows side in a while, but it is frustrating to not find a fix and see pretty much no response from Apple. Have I missed a fix to this problem? Because it has been happening for years now. Thanks for the help!
