I have no audio outputs accept for optical. No headphone Jack. No HDMI OUT. TV does not support arc. I cannot change my input via remote at all. There are no options available. I cannot change anything about the audio accept turn internal speaker Tv speakers on/off. My LG is probably 2006 or 07. I hooked up sound bar. I can get sound out of my Roku2 box but when I switch back to TV the sound does not come through the sound bar anymore. I hooked sound bar up with optical port from sound bar to TV. My Roku 2 box is plugged into the HDMI INPUT on the TV coming straight from Roku 2 box. Xbox has no sound either. Surely there is a way to get sound to soundbar from Tv?! I have local channels only. Antenna TV. My soundbar does not have HDMI ports. Only optical, USB, RCA and Aux. Remember I cannot change anything in audio or inputs? Can someone please help me?
