To connect a sound bar system to your TV, use an optical audio cable to connect the optical digital output on the TV to the optical digital input on the sound bar. If your TV supports the audio channel return feature, use an HDMI cable to connect the devices instead.
If you have unobstructed access to the rear panel of your TV, connect peripheral devices directly to the TV using its HDMI inputs, and connect the TV separately to the sound bar, allowing the latter to output sound from all devices. If you have a wall-mounted TV, connect the devices to the HDMI inputs on the sound bar, and connect it to the TV via an HDMI cable to transfer the video signal. If your TV doesn’t support the audio channel return feature, connect an additional optical audio cable to the TV.
