My Vizio soundbar is not connected to my TV. How can I connect it?
Neither the TV nor Vizio Soundbar will function if the cable is plugged into the wrong port. HDMI 1 (ARC) on the TV is recommended, while HDMI Out (ARC) is recommended on the soundbar. You may also need to enable CEC and ARC, unplug other devices, and modify the Audio Output settings.
