The no-audio bug seems to have become less and less frequent lately. I DID experience quite a fright when I was flipping thru the DirecTV channels and I was nailed by speaker-busting noise from all channels including the sub. Only a power-off solved the problem, it got so loud the clipping lights on my amp all came on steadily. Luckily I was quick to turn the thing off and no damage to my speakers resulted.
