The simplest way to link a Samsung soundbar
Most Samsung soundbars connect to your TV through a single cable or wireless connection, and the TV handles the rest automatically. The easiest method is HDMI ARC (Audio Return Channel), which uses one cable to send both picture and sound from your TV to the soundbar. If your TV and soundbar both have HDMI ports marked ARC or eARC, this is the route to try first — it takes about two minutes and requires no menu diving.
If HDMI ARC is not an option, optical cable (a thin, square connector) works on almost every TV and soundbar made in the last ten years. Bluetooth is the slowest to set up but works if you have no cables available. All three methods produce the same sound quality once connected; the difference is only in setup time and cable clutter.
Key Takeaways
- HDMI ARC is the fastest connection method and requires only one cable plugged into matching ports on both devices.
- Optical cable is the most reliable backup if your TV does not have an ARC port, and works with nearly all Samsung soundbars.
- After connecting the cable, you must tell your TV to send sound to the soundbar through its audio settings — the cable alone does not do this.
- Bluetooth pairing takes longer but works if you have no cables, and you only need to pair once.
Connecting with HDMI ARC (the fastest method)
Look at the back of your TV for an HDMI port labeled ARC, eARC, or sometimes just a port number with "ARC" printed nearby. On your Samsung soundbar, find the HDMI port on the back (most soundbars have one). Plug an HDMI cable into the TV's ARC port and the other end into the soundbar's HDMI port.
Turn on both devices. Pick up your TV remote and go to Settings (usually a gear icon), then Sound or Audio Output. Look for an option called Speaker or Audio Out and select it. You should see "HDMI ARC" or "Soundbar" as an option — select that. Your TV will now send all sound to the soundbar instead of its built-in speakers. Test it by turning up the volume on the soundbar remote; you should hear sound increase.
If you see no HDMI ARC option in your TV's settings, your TV does not have this port. Move to the optical cable method instead.
Connecting with an optical cable (the reliable backup)
An optical cable is a thin, square connector that looks like a small plastic tube. Find the optical port on the back of your TV — it is usually labeled "Optical Out" or "Digital Audio Out" and has a small red light inside. On your Samsung soundbar, locate the optical port on the back (it is the same shape). Plug the optical cable into both ports until you hear a small click.
Turn on both devices. On your TV remote, go to Settings, then Sound or Audio Output. Find the option for Speaker or Audio Out and select Optical or Digital Audio. Your TV will now send sound through the cable to the soundbar. Turn up the soundbar volume to test — you should hear sound come through.
Optical cable is slower than HDMI ARC only in the sense that it carries audio only, not video, but this does not affect what you hear. Many people prefer optical because it is more stable on older TVs and soundbars.
Pairing your soundbar with Bluetooth
If you have no cables available, Bluetooth is your option, though it takes longer to set up. On your Samsung soundbar, press and hold the Bluetooth button on the remote (or on the soundbar itself if there is one) until you see a blue light blinking. This means the soundbar is searching for a device to pair with.
On your TV remote, go to Settings, then Sound or Bluetooth. Select Bluetooth and look for your soundbar model number in the list of available devices. Select it. The TV and soundbar will pair, and the blinking light on the soundbar should turn solid blue. You only need to do this once; they will reconnect automatically when you turn both on in the future.
Bluetooth works well for everyday use, but it can occasionally drop the connection if something is blocking the signal between the TV and soundbar. If you notice sound cutting out, move the soundbar closer to the TV or remove obstacles between them.
What to do if sound still comes from the TV speakers
If you connected the cable but still hear sound from your TV instead of the soundbar, the TV is not sending audio to the soundbar yet. Go back to your TV's Settings, find Sound or Audio Output, and make sure you selected the soundbar or external speaker option. Some TVs call this "Speaker Select" or "Audio Out Device."
If the soundbar is listed but grayed out or unavailable, unplug both devices for 30 seconds, plug them back in, and try again. Sometimes the connection needs a fresh start. If you are using optical cable, check that the cable is pushed all the way into both ports — a loose connection will not work.
Controlling volume and switching between inputs
Once connected, use the soundbar remote to control volume — your TV remote volume buttons may not work anymore, and that is normal. If you want to use your TV remote for volume, some Samsung soundbars have a setting in their menu to allow this, but it varies by model. Check your soundbar's manual or the Samsung support website for your specific model number.
If you have a cable box, gaming console, or streaming device plugged into your TV, the soundbar will play sound from all of them automatically once you have set the TV to send audio to the soundbar. You do not need to reconnect anything — just switch TV inputs as usual, and the soundbar follows along.
Troubleshooting no sound from the soundbar
If you see the connection is made but hear no sound, check that the soundbar is turned on and the volume is not at zero. Look at the soundbar display or remote — it should show a volume number or a bar. If the volume is at 0, press the up button on the soundbar remote.
Next, go back to your TV's audio settings and confirm the soundbar is still selected as the audio output. Sometimes a TV update or power cycle will reset this setting back to the TV speakers. If it has reset, select the soundbar again. If you are using HDMI ARC and still have no sound after checking these steps, try the optical cable method instead — HDMI ARC can be finicky on some TV models.
Frequently Asked Questions
Do I need a special HDMI cable for ARC?
No. Any standard HDMI cable works for ARC. You do not need to buy a cable labeled "ARC" — the feature is built into the ports, not the cable. If you already have an HDMI cable at home, use that one.
Can I use both HDMI ARC and optical cable at the same time?
You can plug both cables in, but your TV will only send sound through one at a time. Pick whichever one works best for you and leave the other plugged in as a backup. If one stops working, you can switch to the other without unplugging anything.
Why does my soundbar keep disconnecting from Bluetooth?
Bluetooth has a shorter range than wired connections and can drop if something blocks the signal between your TV and soundbar. Move the soundbar closer to the TV, remove obstacles like metal objects or thick walls between them, or switch to an optical cable for a more stable connection.
Will the soundbar work with my old TV?
Most Samsung soundbars work with any TV made in the last 15 years. If your TV has an HDMI port or optical port, the soundbar will connect. If your TV is older and has neither, you may need an adapter, which you can find at any electronics store for under $20.
What if my soundbar remote does not have a Bluetooth button?
Older Samsung soundbars may not have a dedicated Bluetooth button. Check the soundbar itself for a small button labeled Bluetooth or a pairing button, usually on the back or side. Hold it for three seconds until a light blinks. If you cannot find one, check your soundbar's model number on the Samsung website for the manual.
