We bought a new samsung TV, we upgraded from an old tv with no HDMI. we have a HD rogers box and im wondering how to hook up the rogers box to the receiver for surround sound. we got picture for the rogers but no audio is coming through the speakers. I used those red and white cables from the back of the rogers box to the receiver to try and get surround sound for TV, but its not working. What am i doing wrong? Can anyone tell me the proper way to do all the setup?
