Most likely the TV is not going to have an optical input, and unfortunately, if analog input is run to the TV, that signal won't be able to be sent back out through the optical output. Now, if you also have an optical output on the TV (which is unlikely, I believe), then I believe it's possible to have audio input to the TV, then back out to the receiver. Please correct me if I'm wrong.
