1st...I am an electronics idiot! I have an 31" Samsung LCD TV and a Onkyo 7.1 surround system. I recieve digital/HD from Time/Warner cable. I have a HDMI cable running from cable box to surround reciever and another HDMI cable running from surround reciever to TV. I am getting no sound from the TV only thru the surround speakers. Am I hooked up wrong? This is all new equipment and the manuals are making no sense to me. HELP!!
