Chad,
I often disagree with your advice, but I think you may have hit the nail on the head this time. Since DirecTV installed Whole Home, connecting the receivers to our LAN, a noticeable hum was introduced to what had been a silent system. I thought the unit they attached to the receiver might be too close to something, but perhaps it needs to be grounded. I'll follow up on your advice. Thanks.
