I would somewhat agree with Chili's statement. It's not always my 1070. I've noticed since receiving my 1070 back from it's factory firmware update then when I do get a no-audio incident, 9 times out of 10, it's my Comcast/Motorolla DVR box. Simply hitting the "jump back 15 seconds" button acts as a refresh and that brings the sound back. But with that said, I ran my Yamaha RX-V750 for over a year with an identical model box and never got no-audio bugs. But then again, I wasn't hearing Outlaw-quality sound either. You win much and lose a little. If all of life were like that, I'd be in good shape!
