Well, my 721 is doing it again today. Constantly. Plays for a few minutes, then loses audio. Then loses signal. Signal comes back, but no audio. Change the channel and then back and audio is back - for a couple of minutes.
It was working better for a week or so, but now I think it's actually worse than it was originally.
