Sometimes when I start Garageband it makes a highpitched whining sound until I turn down the volume. I think it might have something to do with the mic.
I think you need to give a bit more info, what mac are you using? are you using a sound card or usb in/out? do you have any inputs? And what sort of sound is the whining? is it like feed back, is it loud, is it continuious?
