I plan on cutting the cable tv cord (to save $110 per month on the cable bill). I have a 2112ci...got an HD antenna and receive network channels perfectly. I have the HD antenna going straight into my Panasonic TC-P50G15 TV. I connected an optical audio cable from the TV to the 2112ci optical (tv) in. I turned the tv speakers 'off'. I set up the 2112ci for input TV to receive OPT audio. When I turn the 2112ci to TV input, there is no sound coming from the TV (optical cord). I can't figure out what I'm doing wrong. I even disconnected the HDMI cable I had going from the TV to the 2112ci when I was using the cable box.
