David has a Blu-ray player in his home theater that can run Netflix. When he switches back to TV, he's getting audio issues, though. Leo says that he has a similar problem and it's the TV set that tells the receiver what audio to play. It's a fault in the hand shaking and Leo says it's very common. Leo also advises making sure his HDMI cable is secure. Often it can get loose, causing connection errors. Make sure everything is plugged in solid. There's also issues in shifting from 720p-1080i-1080p. Scott thinks it may be a fault in the cable box.
