The surround worked the day it was installed and hasn't since.
Hello,
When the DISH Network installed hooked up their DVR, did they connect it via HDMI? If so, then it could be a bad HDMI connection. I would bet they simply bypassed your receiver and went straight to the TV, which is why no audio comes out of your receiver. You can test this by turning on your DVR and TV. If you see picture with your receiver OFF, then they bypassed your receiver. You'll need to hook up and HDMI cable from the DVR into the receiver and then out of the receiver to the TV.
