How to Connect a Samsung Soundbar to Your TV

The basic connection: HDMI is usually the fastest route

Most Samsung soundbars connect to your TV through a single HDMI cable plugged into the HDMI ARC or eARC port on the back of your TV. ARC stands for Audio Return Channel — it lets your TV send sound back to the soundbar instead of just receiving it. This is the simplest setup because one cable handles both picture and sound, and your TV remote often controls the soundbar volume automatically.

Before you plug anything in, check the back of your TV for a port labeled HDMI ARC or HDMI eARC (eARC is the newer, faster version). If your TV has both, use eARC. If you cannot find either label, look at your TV's manual or settings — sometimes the port is not marked but the TV's menu will tell you which HDMI port supports ARC. Plug one end of an HDMI cable into that port and the other end into the HDMI input on the back of your Samsung soundbar.

Key Takeaways

HDMI ARC or eARC is the fastest connection method and requires only one cable between your TV and soundbar.
If your TV does not have HDMI ARC, you can use an optical audio cable instead, though you will need to plug the soundbar into power separately.
Bluetooth works for streaming music from your phone but does not carry TV sound reliably and should not be your main connection.
After connecting the cable, go into your TV's sound settings and select the soundbar as your audio output device.
If you hear no sound, check that the soundbar is powered on and that your TV is not muted or set to internal speakers.

Optical audio cable: the backup when HDMI ARC is not available

If your TV does not have an HDMI ARC port, an optical audio cable (also called a Toslink cable) is the next best option. This thin cable carries sound from your TV to the soundbar. You will find the optical port on the back of your TV — it looks like a small square hole with a red or black cover. Plug one end into your TV's optical out port and the other into the optical in port on the back of your Samsung soundbar.

With an optical connection, you will also need to plug the soundbar into a power outlet using its power cable, since optical does not carry power like HDMI does. After connecting both cables, go into your TV's settings, find the sound or audio menu, and change the audio output from "Internal Speakers" or "TV Speaker" to "Optical Out" or "External Speaker." Your soundbar should then play all the sound from your TV.

Bluetooth: good for phones, not reliable for TV sound

Samsung soundbars have Bluetooth, but it is not the best way to connect your TV. Bluetooth works well for playing music from your phone or tablet, but it can drop out or lag when you are watching TV, and it does not work if your TV is off. Use Bluetooth only if your TV does not have HDMI ARC or an optical port, or if you want to play music from a phone while the TV is off.

To pair your soundbar with your TV over Bluetooth, press the Bluetooth button on the soundbar remote or on the soundbar itself (usually marked with a Bluetooth symbol). Then go into your TV's Bluetooth settings, search for available devices, and select your Samsung soundbar from the list. Once paired, the soundbar will remember your TV and reconnect automatically when you turn both on.

Turning on the soundbar and adjusting TV settings

After you plug in the cable, press the power button on the soundbar or its remote. You should see a light turn on — usually blue or white. Then turn on your TV and play something with sound, like a streaming app or a broadcast channel. If you hear sound from the soundbar, the connection is working.

If you hear nothing, go into your TV's settings menu. Look for a section called Sound, Audio, or Speaker Settings. Find the option for audio output or speaker selection and make sure it is set to the soundbar, not the TV's internal speakers. Some TVs call this "External Speaker" or "HDMI ARC Device." If your TV has a setting called "Dolby Atmos" or "Enhanced Audio," you can turn it on here too — it improves sound quality if your soundbar supports it.

Controlling volume with your TV remote

If you used HDMI ARC, your TV remote should control the soundbar volume automatically. Press the volume up or down buttons on your TV remote and watch the soundbar volume change. If this does not work, go back into your TV's sound settings and look for an option called "HDMI Device Control," "CEC," or "Anynet+." Turn this on — it tells your TV to send volume commands to the soundbar.

If you used an optical cable or Bluetooth, your TV remote will not control the soundbar volume. You will need to use the soundbar's remote or the Samsung SmartThings app on your phone to adjust volume. Some soundbars have a physical volume knob on the front that you can turn by hand as well.

Connecting multiple devices: TV, streaming box, and game console

If you have a streaming device like a Roku, Apple TV, or Fire Stick, or a game console like a PlayStation or Xbox, you can connect them directly to the soundbar instead of the TV. Plug their HDMI cables into the HDMI inputs on the soundbar, then plug one HDMI cable from the soundbar into your TV's HDMI ARC port. This way, sound from all your devices goes through the soundbar first, then to your TV.

This setup is called daisy-chaining, and it works well if your soundbar has multiple HDMI inputs. Check the back of your soundbar — if it has two or three HDMI ports, you can use this method. If it has only one, stick with connecting devices directly to your TV and letting the TV send sound to the soundbar through ARC.

Troubleshooting: no sound or intermittent connection

If you plugged everything in but hear no sound, start with the basics. Make sure the soundbar is powered on — look for a light on the front. Check that your TV is not muted by pressing the mute button on your TV remote. Then go into your TV's sound settings again and confirm the audio output is set to the soundbar, not the internal speakers.

If sound cuts out randomly or only works sometimes, the cable connection might be loose. Unplug the HDMI or optical cable from both the TV and soundbar, wait five seconds, and plug it back in firmly. If you are using HDMI ARC, try a different HDMI cable — some older cables do not support ARC properly. If the problem continues, restart both the TV and soundbar by unplugging them for 30 seconds, then plugging them back in.

If you are using Bluetooth and the connection keeps dropping, move the soundbar closer to the TV or remove any large metal objects between them. Bluetooth has a range of about 30 feet, but walls and metal can interfere. If moving things does not help, forget the device from both the soundbar and TV, then pair them again from scratch.

Frequently Asked Questions

Do I need a special HDMI cable for ARC?

No. Any standard HDMI cable works with ARC. You do not need to buy an expensive "ARC cable" — the feature is built into the port, not the cable. That said, older or damaged cables sometimes do not work reliably, so if you have trouble, try a newer cable.

Can I use the soundbar with a TV that does not have ARC?

Yes. Use an optical audio cable instead. Optical works with almost every TV made in the last 15 years. If your TV has neither HDMI ARC nor an optical port, Bluetooth is your only option, though it is less reliable for TV sound.

Why does my soundbar work with my phone but not my TV?

If Bluetooth works with your phone but not your TV, the TV may not have Bluetooth, or Bluetooth may be turned off in the TV's settings. Check your TV's manual to see if it has Bluetooth. If it does, go into settings and turn Bluetooth on. If it does not, use HDMI ARC or optical instead.

Will the soundbar work if my TV is off?

Only if you are using Bluetooth to play music from your phone. If you are using HDMI ARC or optical, the soundbar needs the TV to be on because the TV is sending the sound signal. The soundbar cannot produce sound on its own without an input source.

What is the difference between HDMI ARC and eARC?

eARC is newer and faster, but both do the same job — they send sound from your TV to the soundbar through one HDMI cable. eARC supports higher-quality audio formats and works better with newer soundbars. If your TV has eARC, use it. If it only has ARC, that works fine too.
