How to Set Up and Connect Sonos Arc to the TV (and Other Devices)
If you’re a Sonos whiz through and through, you’ll know that the Arc can be set up using the brand’s controller program. This is done before connecting the soundbar to TV using the provided HDMI cable, which is compatible with both ARC and eARC protocols. If there are no available ports for HDMI, you can link the home theater device via an optical audio adapter instead.
