My problem is the same as lots of other posts. When I power up my TV I will have audio. My DVR settings is set to Surround. As soon as I change the channel I will lose the audio. I can switch channels and still no audio. I like many others have rebooted, reseated cables etc. which in some cases work. Rebooting takes forever as we all know. What I found works for me is in the "Settings" I switch the "Output resoultion" from my current setting of 1080i to 720p. The audio comes back, I save it then switch it back to 1080i and save it. It works all day unitl I power down. When I power up the next time as soon as I switch channels I lose audio again. I go thru the same motions above and it works. It's easy and alot quicker than rebooting the DVR box. Hopefully there will be a "real" fix for the problem soon.
