What is overdriven audio? A few days ago my obery audio gets low, drops out and comes back. I do not know if it is the tv or satellite. Since I have company till after new years I probably will not have much time for testing. I was using composite and changed the wire to another one and tryyed 2 different avr tv imputs. I changed to an hdmi wire imput with the identical results. Might try orby on a small portable tv and check.to see if I still have audio problems. Also there is a slight buzz in the tv.
