Hello all, I'm watchin some football and saw that Fox broadcasts in 5.1 Audio. I don't have HD cable, but it still broadcasts 5.1 audio right? I assumed so, and now I'm confused why I can't hear any sound through my sound system. I have an optical cable going from the digital audio out port on my tv to the digital audio in on my receiver. I set my receiver to D-In, but no sound. Anyone know what to do? Thanks a bunch.
