Basically what I'm trying to do is use a digital coax cable from my cable box to my receiver (Harmon/Kardon AVR 125 receiver). As of right now, I get no sound out of any speakers using that input, but can get sound through the analog connections (cable box to receiver, then the receiver to the TV). I can get digital sound on certain channels (digital movie channels), but not other channels. I thought it was just that my cable provider didn't send out digital sound through those channels, but a friend of mine is getting sound through his. Is it possible that he's just going through analog inputs and somehow has it coming out all of the speakers on these local channels or is there some connection on mine that I need on my setup? If it is just through analog connections, is there a way to make it so that sound can come out in more than 2 channels? The only reason why I ask is because I would like to be able to watch, for example, the NBA Finals with surround sound.
