    I have the Mac Pro and I have an external hard drive that I connect via the front FireWire panel on the Mac Pro. When the drive is off and the FireWire cable is connected to the computer, I get a "buzz" in the speakers. When I turn on the drive or disconnect the cable, the buzzing is gone? Any ideas?

    Nobody? This happens even when the drive is on randomly?

    I know this thread should have died in 2007, but I'm experiencing a really bad speaker buzz from my LCD TV when my NewerTech miniStack v3 is connected to the FireWire port on the back of my Mac mini.

    The miniStack doesn't have to be on, just plugged in and as soon as the FireWire cable is attached, it begins to buzz horribly. I'm beginning to wonder if spending money on a power filter will fix this issue, or I'll have to move the Mac mini and the miniStack to the lower shelf under the TV.

    You're getting a ground loop. It's a bit complicated to explain quickly but if you google "ground loop" there's heaps of info.
