Answer: Connect one end of an HDMI cable to the HDMI OUT (ARC) port on your sound bar. This will allow you to set up your sound connection via HDMI. Connect the other end of the cable to the HDMI 1 (ARC) port on the back of your TV. This will allow your TV to send audio signals to the sound bar via the HDMI cable.
