How to Connect a Soundbar to Your Samsung TV

The fastest way: HDMI ARC or eARC

Most Samsung TVs made in the last five years have an HDMI port marked ARC or eARC — usually HDMI 3 or 4. If your soundbar also has HDMI eARC, this is the simplest connection: one cable runs from the TV to the soundbar, and the TV sends audio through it automatically. You do not need a separate audio cable.

Plug the HDMI cable into the eARC port on both devices. Then go to your Samsung TV's Settings menu, select Sound, and turn on HDMI Audio Format. The soundbar should power on and begin playing sound from the TV within seconds. If it does not, restart both devices and check that the cable is fully seated in both ports.

eARC is faster and more reliable than the older ARC standard because it handles higher-quality audio formats. If your TV or soundbar is older and only supports ARC (not eARC), the same HDMI connection works, but you may see occasional audio dropouts with certain streaming apps.

Key Takeaways

HDMI eARC is the fastest method and requires only one cable from your TV to the soundbar.
If your soundbar does not have HDMI, use an optical audio cable from the TV's optical port to the soundbar's optical input.
Bluetooth works for wireless connection but can lag during movies and may disconnect if the soundbar moves out of range.
After connecting, go to your TV's Sound settings and select the soundbar as the audio output device.
If sound does not play, restart both devices and check that the cable is fully inserted or Bluetooth is paired.

Optical audio cable: the reliable backup

If your soundbar does not have HDMI eARC, use an optical audio cable instead. This is a thin, square connector that carries digital sound. Your Samsung TV has an optical port on the back or side, usually labeled Optical Out or S/PDIF. The soundbar has a matching port on its rear panel.

Insert one end of the optical cable into the TV's optical port and the other into the soundbar's optical input. Push until you hear a click. Then go to Settings > Sound on your TV and select Optical as the audio output. The soundbar will begin playing sound from the TV, apps, and external devices like cable boxes or game consoles.

Optical cables do not carry the newest audio formats like Dolby Atmos, but they work reliably with all Samsung TVs and most soundbars. They also do not require power or pairing, so they are less likely to fail than wireless connections.

Bluetooth: wireless but with trade-offs

Samsung TVs can pair with Bluetooth soundbars, which means no cables running across your wall. To pair, go to Settings > Sound > Sound Output on your TV and select Bluetooth Speaker. Then put your soundbar in pairing mode — usually by holding a button on the remote or the soundbar itself for three seconds — and select it from the TV's list.

Bluetooth works well for everyday watching, but it has two real drawbacks. First, there is a slight delay between what you see on screen and what you hear, which becomes noticeable during movies and sports. Second, if the soundbar moves more than 30 feet from the TV or something blocks the signal, the connection drops and you lose sound until you manually reconnect.

Use Bluetooth only if you cannot run a cable and do not mind occasional reconnection. For regular viewing, HDMI eARC or optical is more stable.

Connecting a soundbar with a separate subwoofer

Many soundbars come with a wireless subwoofer that pairs to the soundbar itself, not the TV. Connect the soundbar to your TV using HDMI eARC or optical, then follow the subwoofer's manual to pair it to the soundbar. This usually means pressing a pairing button on both devices within a few seconds of each other.

The subwoofer communicates with the soundbar wirelessly, so you only need one cable from the TV to the soundbar. Place the subwoofer on the floor near your TV or in a corner of the room — it does not need to be in the same spot as the soundbar, and it does not need to be plugged into the TV.

If the subwoofer does not pair, check that both devices are powered on and within 10 feet of each other. Restart both and try pairing again. If it still does not work, consult the subwoofer's manual for a factory reset procedure.

Adjusting sound settings after connection

Once your soundbar is connected, go to Settings > Sound on your TV and check the Sound Output setting. Make sure it is set to the soundbar, not the TV speakers. You may also see options for Dolby Atmos or surround sound — these depend on what your soundbar supports and what you are watching.

If the soundbar is too quiet or too loud, use the soundbar's remote to adjust the volume. Most Samsung TVs also let you control soundbar volume from the TV remote once they are paired, but this only works if the soundbar is connected via HDMI eARC or Bluetooth.

If you are watching streaming apps like Netflix or Prime Video and the sound is not coming from the soundbar, go into that app's audio settings and make sure it is not set to a different output. Some apps default to TV speakers and override your TV's sound settings.

Troubleshooting when sound does not play

If you connected the soundbar but hear nothing, first check that the soundbar is powered on — look for a light on the front panel. Then restart both the TV and soundbar by unplugging them for 10 seconds and plugging them back in.

Next, go to Settings > Sound > Sound Output on your TV and confirm the soundbar is selected. If it is not listed, the connection may not be complete. For HDMI eARC, unplug the cable from both ends, wait five seconds, and plug it back in firmly. For optical, do the same with the optical cable. For Bluetooth, go to Settings > Sound > Sound Output and select Bluetooth Speaker again to re-pair.

If the soundbar is listed but still produces no sound, try switching to a different audio output (like TV Speaker) and then back to the soundbar. This forces the TV to re-initialize the connection. If you are using HDMI eARC, also check that HDMI Audio Format is turned on in your TV's Sound settings.

When to use each connection type

Use HDMI eARC if your soundbar has it — it is the fastest and most reliable option. Use optical if your soundbar does not have HDMI or if you want to avoid any wireless pairing. Use Bluetooth only if you cannot run a cable and do not mind occasional reconnection or slight audio delay.

If you have both a soundbar and a subwoofer, connect the soundbar to the TV and let the subwoofer pair to the soundbar wirelessly. This keeps your setup clean and avoids extra cables.

For gaming consoles, cable boxes, or other devices plugged into your TV, the soundbar will play their audio automatically once it is connected to the TV. You do not need to connect those devices to the soundbar separately.

Frequently Asked Questions

Can I use both the TV speakers and the soundbar at the same time?

No. Once you select the soundbar as the audio output in your TV's Sound settings, the TV speakers turn off. If you want to switch back to TV speakers, go to Settings > Sound > Sound Output and select TV Speaker.

Do I need to turn the soundbar on and off with the TV?

Not necessarily. Most soundbars have an auto-off feature that powers them down after 10 or 15 minutes of silence. You can also leave the soundbar on all the time — it uses very little power in standby mode. Some soundbars connected via HDMI eARC will power on automatically when the TV turns on, but this depends on the model.

What if my soundbar remote does not control the TV volume?

The TV remote should control soundbar volume if they are connected via HDMI eARC or Bluetooth. If it does not, use the soundbar's own remote to adjust volume. You can also go to Settings > Sound on your TV and use the volume buttons there.

Can I connect my soundbar to a different HDMI port if eARC is not available?

No. Regular HDMI ports do not carry audio from the TV to external devices. You must use the port marked ARC or eARC, or use an optical cable instead.

Why is there a delay between the picture and sound when using Bluetooth?

Bluetooth has built-in latency — the time it takes for the signal to travel from the TV to the soundbar. This is usually 100 to 200 milliseconds, which is noticeable during movies but less so during regular TV. HDMI eARC and optical have almost no delay, which is why they are better for movies and sports.
