I need some help! I'm not the most sound savvy! I am trying to connect my TCL tv to my onkyo receiver. The only output from the tv is a spdif. The receiver has two optical coaxials and one digital. I bought a digital coaxial cable and connected it to the tv and receiver and no sound. (Yes, I made sure it was on the right channel!) I also turned the speakers off on the tv through the menu and still no sound. I tried the second coaxial spot and no sound either. I'm sure there is probably a simple solution, but I have no idea what it is! Help!
