I recently purchased a Philips TV Model# 46PFL7505D/F7, a Sony Blue ray player Model# BDP BX57, and a Vizio Sound bar Model# VSB210WS. The TV has only one audio out port. That is a digital coaxial plug. The sound bar has only one option for digital audio in. That is an optical port. So I purchased an optical transmitter kit, which is an adaptor to convert digital coaxial audio to optical. That is to say, the tv is wired to the sound bar through this adaptor. The Blue ray player is wired to the TV via an HDMI connection. I recieve TV programing via a very good antenna system with no cable or sattelite connection. The problem is while the sound bar is working fine with the Blue ray player (Netflix included), I get nothing from the Sound bar when watching on air TV programing. I have talked to Philips and other folks, So far nothing. If anybody out there has ran across anything like this, PLEASE HELP!
