Do you want sound to come from your TV? Since you're using a cable card equipped TV and have audio outputs on the TV that will constantly be used, I would recommend to completely turn off the audio from the TV. I just did this for a friend. He wanted to only utilize his surround system for hearing everything, (that's why he bought the surround system). What I did was access his TV's menu, went under the audio section, turned audio output to on and turned off the TV speakers, it was labeled as AVC or something??? On his TV, a (no sound) signal would appear that would deny my command to turn up or down the TV volume when I pushed the buttons on the remote. This was my check to make sure I had everything correct. I don't assume all makes and models will flash a signal.
