I am hoping there are some experts out there that can assist me in figuring out my issue with a Home Theater Setup.
I have a new Sony Bravia LCD KDL46EX700, and I have it hooked up via hmdi (video 1) to my directtv receiver. I have a Harman Kardon AVR135 Receiver. I have an optical output from my tv and put it into my optical input in the back of my receiver, however whenever I switch "Video 1" to optical in the settings it won't register the new input signal. However, if I take the exact same output from the tv and plug it into the front of the receiver (optical "3" as noted on the front panel), it works and I can get the sound from my television through my home sound system. This is not ideal, though. I would like it to work in the back of the receiver, and not have this big ugly cord going into the front of my audio equipment.
Any help is appreciated!
