I am trying to connect my Charter set-top box to my TV(LG LM8600) through the Sony HT-CT150 soundbar via the ARC feature. I have managed to connect my Sony 3D-BD player with Simplink and sound works as expected. But I couldn't get the cable to display on the TV with the setup. Just to go over the setup again, I have one cable running from the TV HDMI ARC port to the HDMI ARC on the soundbar subwoofer. BD player is connected to BD HDMI and Cable box is connected SAT/CATV HDMI on the subwoofer. All cables are hi-speed 1.4.
According to the set-top box manuals, it is HDMI-CEC compatible but can't seem to find it anywhere in the settings menu to enable it. Found one thread about pressing "A"on the remote in the General settings menu to access the "Advanced Settings" menu with additional HDMI settings but it didn't work for me.
Any ideas how to get this working?
