I recently purchased a Yamaha HTR-3064 receiver, and have it hooked up to my Samsung 46" LED edgelit TV on Saturday. I have the cable box connected via HDMI cable to the receiver, and an HDMI cable running from the receiver to the TV. I have a digital audio cable going out from the TV back to the receiver for sound. Everything worked perfectly on Saturday(when i bought it) and Sunday. Yesterday i turned it on and now there is no audio to the receiver. The picture is still going to the tv, and i can listen to the tv with the tv speakers, but when i try to get the receiver to play the tv sound, i get nothing. The receiver is functioning, because i can listen to the radio and the test tones work fine for all five channels and the subwoofer. Anybody have any idea whether this might be a setting or something, or maybe the cable went bad? The cable is brand new, so it is hard for me to believe that either the receiver or the cable went bad already. It just stopped working! Help!
