I have a problem with my Logitech Revue where the audio flickers on/off at unpredictable intervals. Basically, the sound will go out for about 3 seconds or so at any time. This has actually been happening for a while. I returned an older Logitech Revue with Google TV because of this problem and I recently get a new one, which has this same problem now. My Revue is connected to my DirecTV DVR box (HR-22), which is connected to my Onkyo receiver (TX-NR809). Since I'm guessing not everyone has this problem, there must be a compatibility issue. Any ideas for how I can try to resolve this problem?
