I just changed the location of my A/V reciever and now plug it into a different outlet. The audio connection for dvd and high def viewing is from my HTPC to my H/K 7200 via digital (coax). When the AC compressor kicks on, I loose audio for 2-3 seconds. It then comes back, but I get the dropout the next time the AC cycles. The AC compressor is physically located just oustide where the new outelt and reciver are now located. Any ideas?? Come to think of it, I don't notiece the audio dropouts on the tivo digital (optical) connection to the receiver.
