This sort of thing always reminds me of Christmas Vacation's Grandma saying "it's making a funny squeaking sound". So we're all at my brother- in-laws and he has a Mac mini connected to a pioneer avr, amongst other connections like blu ray and wii. Only when feeding from the mini does he get a high pitched whine, both with streaming and disc play. Not a 60hz noise, but much higher. He does not have cable TV and all electrical connections run thru a 2-prong plug, so no ground-loop issue.

Any thoughts?
