Definitely paid too much for the optical cable because I went to Radio Shack. I know I could've gotten one cheaper online, but I'm impatient sometimes.
1. Once the optical cable is connected, does the sound only get sent from the tv to the AVR when the AVR's source is set to "TV"? Since I don't need the optical cable for the other sources, does the AVR know this?
2. How can I tell if my tv has ARC? I have a Samsung L46c630 and I've looked at specs online, but haven't found any mention of ARC...if mine has ARC, I'll get an hdmi 1.4 cable.
