Your Sound Bar supports HDMI with Audio Return Channel (ARC). The TV must support HDMI ARC to hear TV audio on your Sound Bar using an HDMI cable. ARC feeds TV digital audio to your Sound Bar.
To connect, insert the HDMI cable in the TV HDMI port labeled HDMI ARC. Your TVs HDMI ARC port may be labeled differently. Refer to your TV owners manual for HDMI ARC and CEC operation of your TV.
Press the ARC button on the Sound Bar remote to select the ARC input.
