I have this older LED flat panel, which has a great picture on it still, but I'm trying to hook up my receiver for better sound through bookshelf speakers/subwoofer. I have a Denon AVR-S720W receiver, and a SAMSUNG UN55FH6003 television. I've included a picture of the back of the tv, which I believe has no form of audio out.

Is there any type of adapter or anything that I could make any of these ports into an audio out?
