How to Connect Soundbar | TV Setup, HDMI & Bluetooth

Connect a soundbar to a TV using an HDMI ARC/eARC cable for the best audio, or an optical cable if ARC is unavailable.

Setting up a soundbar is straightforward once you know the ports. The single best way to connect a soundbar is with an HDMI cable using the ARC or eARC ports, because it carries TV audio back to the soundbar and lets your TV remote control the volume. If your TV lacks ARC, an optical digital audio cable works almost as well for sound quality. Bluetooth pairing is the wireless fallback for phones and some TVs, though it can add slight audio lag. Whichever cable you use, the trick is matching the labeled ports and then switching the TV’s audio output away from its built-in speakers.

Connect Soundbar With HDMI ARC: The Step Order That Works

HDMI ARC (Audio Return Channel) is the connection to prefer. It sends audio both directions over one cable, supports the highest-quality formats with eARC, and passes your TV remote’s volume commands straight to the soundbar. Sony’s support documentation confirms TV-remote control only works over HDMI with its Control for HDMI setting enabled.

Before plugging anything in, power off both the TV and the soundbar. Then run the HDMI cable from the port labeled HDMI IN (ARC) or HDMI IN (eARC/ARC) on the TV to the port labeled HDMI OUT (TV-ARC) or HDMI OUT (eARC/ARC) on the soundbar. That port pairing matters — Samsung’s setup guide stresses that the soundbar’s HDMI OUT port is for connecting to the TV, while its HDMI IN ports are for external sources like a console or Blu-ray player. Plugging into the wrong one is a common mistake.

Once both ends are connected, power both devices back on. The soundbar should automatically switch to its ARC input. If you hear no sound, check the TV’s audio output setting and select the HDMI ARC option. Sony and Samsung both state ARC only works when both the TV and soundbar support the feature, so confirm the port labels before you buy a cable.

Optical Connection: When ARC Is Not Available

If your TV has no ARC port, an optical cable delivers the same audio quality as ARC for standard TV content. Sony’s instructions say to connect the TV’s Optical digital audio out to the soundbar’s OPTICAL IN or DIGITAL AUDIO IN (OPTICAL) port.

After the cable is seated, switch the soundbar’s source to D.IN. or the optical input, then change the TV’s sound output to external speakers or the optical option. Samsung’s setup page also directs you to set the TV output to Optical in the sound settings. The one thing optical can’t do is let the TV remote control the soundbar’s volume — Sony’s guidance is explicit that remote control integration only works over HDMI with Control for HDMI enabled, so keep the soundbar’s own remote nearby.

Bluetooth Pairing for Wireless Audio

Bluetooth is the right choice when you want to play music from a phone or pair a TV that has no ARC and no optical port. Put the soundbar into BT PAIRING mode, then open the TV’s Bluetooth settings and select the soundbar from the Bluetooth Speaker List or Bluetooth Audio Device menu.

Consumer guidance and manufacturer docs both position Bluetooth as a convenience rather than the ideal for TV audio. It introduces noticeable latency between the picture and sound, which makes dialogue-heavy shows feel slightly off. HDMI ARC/eARC is the preferred one-cable solution for quality and control. If Bluetooth is your only option and the lag bothers you, check whether your TV has a dedicated audio delay setting to compensate.

Which Soundbar Connection Should You Use?

Use HDMI ARC if both ports exist, because it combines the best audio quality with the convenience of your TV remote controlling the soundbar. Sony’s support article recommends using only an HDMI cable for that TV-to-soundbar connection when both devices support eARC/ARC. Bluetooth works everywhere but carries latency, so reserve it for casual listening or TVs with no wired audio output at all.

If you’re looking to boost the soundbar’s power further or integrate it into a larger home theater setup, our tested roundup of the best amplifiers for soundbars breaks down the top options.

Whichever connection you choose, confirm the TV’s audio output is set to external speakers, not the built-in ones. That single overlooked setting is the most common reason a new soundbar stays silent.
