I'm fairly certain my receiver is always on.....when we turn our TV on, there's the welcome screen with the black background.

I was worried about the same thing - but the DISH tech on the phone assured me a new box would cause the same problems. Ugh.

Hi everyone, A week ago we started having problems with audio from our 722 unit (we checked our TV and it's not the source of the problem). 75-80% of the time, we get no audio from our box using HDMI. Sometimes we turn it on and it works fine, but most of the time it doesn't. The sound works...
