Sound Keeps Muting. Why?

[KMBass]

I have a Logitech Revue runnig with a Dishnetwork 622 receiver and at least once a day the sound will mute while watching regular TV not even usung the Google TV. We have to turn on the keyboard and press one of the volume keys on the keyboard to get the sound back. It could work OK for the rest of the day or maybe in a hour or two do it again.

Anybody got any ideas what could be causing this?

I'm having similar problems. every so often when i power my tv/ av receiver/ fios box on i have no sound and picture cuts in and out. I have tried calling logitech but there revue customer service sucks now. for me to get it back i have to hit ctrl/ alt/ delete, then it might work fine for days or maybe just until i turn everything off and then back on again. if i find a fix i will let you know
