The simplest way to connect a Samsung soundbar
Most Samsung soundbars connect to your TV using a single HDMI cable, which carries both picture and sound. This is the fastest route and requires no setup beyond plugging in the cable and turning on the soundbar. If your TV has an HDMI port labeled ARC or eARC (Audio Return Channel), use that one — it lets the TV send sound back to the soundbar without a separate audio cable.
If your TV does not have HDMI ARC, you can still connect the soundbar using an optical audio cable, which looks like a thin black cord with a small square connector on each end. This method works on almost every TV made in the last ten years and is nearly as straightforward as HDMI.
Bluetooth is a third option if you want no cables at all, though it is less reliable than wired connections and can occasionally drop the signal. Most people use Bluetooth only as a backup when HDMI or optical is not available.
Key Takeaways
- HDMI ARC is the best choice if your TV has it, because one cable carries both picture and sound from the TV to the soundbar.
- Optical audio cable is the second-best choice and works on nearly all TVs, even older ones without HDMI ARC.
- After you plug in the cable, you may need to tell your TV to send sound to the soundbar instead of its built-in speakers — this is usually in the TV's sound settings.
- Bluetooth works without cables but can drop the connection, so it is best as a backup option rather than your main connection.
Connecting with HDMI ARC — the fastest method
Look at the back of your TV for an HDMI port labeled ARC or eARC. If you see one, plug one end of an HDMI cable into that port and the other end into the HDMI port on the back of your soundbar. Then plug the soundbar into power and turn it on. The TV should automatically detect the soundbar and start sending sound to it within a few seconds.
If the soundbar turns on but you hear no sound, go to your TV's settings menu and look for Sound or Audio. You should see an option that says something like "Sound Output" or "Speaker Settings." Select it and choose the soundbar from the list. On Samsung TVs, this is usually under Settings > Sound > Speaker Settings > TV Speaker Off or External Speaker On.
HDMI ARC is better than regular HDMI because it lets the TV send sound back through the same cable it receives the picture on. With a regular HDMI port, you would need a second optical cable to get sound from the TV to the soundbar, which defeats the purpose of using HDMI in the first place.
Connecting with an optical audio cable — the reliable backup
An optical audio cable has a small square connector that looks like a tiny mailbox slot. Find the optical audio port on the back of your TV — it is usually labeled "Optical Out" or "Digital Audio Out" and is about the size of a headphone jack. Plug one end of the optical cable into that port and the other end into the optical port on the back of your soundbar.
Plug the soundbar into power and turn it on. Then go to your TV's Sound settings and look for "Speaker Settings" or "Sound Output." Choose the optical port or external speaker option from the list. The TV will now send all sound through the optical cable to the soundbar instead of using its built-in speakers.
Optical cables are more reliable than Bluetooth because they use a direct physical connection and do not lose signal. They also work on almost every TV made in the last fifteen years, even if the TV does not have HDMI ARC. The only downside is that you have one more cable behind your TV, but the connection is rock-solid.
Connecting with Bluetooth — the wireless option
If you want no cables at all, you can pair the soundbar to your TV using Bluetooth. On your Samsung soundbar, press the Bluetooth button on the remote or the soundbar itself — you should see a blue light blink on the front of the soundbar, which means it is searching for a device to connect to.
On your TV, go to Settings > Sound > Speaker Settings and look for a Bluetooth option. Select it and choose your soundbar from the list of available devices. The TV and soundbar will pair, and the blue light on the soundbar should stop blinking and stay solid.
Bluetooth works without any cables, but the connection can sometimes drop if there is interference from other wireless devices or if something blocks the signal between the TV and soundbar. If you notice the sound cutting out, move the soundbar closer to the TV or switch to HDMI or optical instead. Most people use Bluetooth only when they cannot run a cable, not as their primary connection.
What to do if you hear sound from both the TV and the soundbar
If sound is coming from both your TV's built-in speakers and the soundbar at the same time, the TV is not set to send all sound to the soundbar. Go to your TV's Sound settings and find the option for Speaker Settings or Sound Output. Look for a setting that says "TV Speaker" and turn it off, or select "External Speaker" or "Soundbar" from the list.
On Samsung TVs, this is usually under Settings > Sound > Speaker Settings. You should see options like "TV Speaker On," "TV Speaker Off," or "External Speaker." Choose the option that turns off the TV's built-in speakers and sends all sound to the soundbar. Once you do this, sound should come only from the soundbar.
Troubleshooting when the soundbar does not turn on or connect
If the soundbar does not turn on at all, check that the power cable is plugged into both the soundbar and a working outlet. Press the power button on the soundbar itself or on the remote — sometimes the remote batteries are dead, so try replacing them if the button on the soundbar does not work.
If the soundbar turns on but does not connect to the TV, unplug the soundbar for thirty seconds and plug it back in. This resets the connection. Then check that your cable is plugged firmly into both the TV and the soundbar — a loose connection is the most common reason a soundbar does not work. If you are using HDMI, try a different HDMI port on your TV. If you are using optical, make sure the cable is pushed all the way in until you hear a small click.
If the soundbar still does not work after trying these steps, check the manual that came with your soundbar or visit Samsung's support website for your specific model number. The model number is usually on the back of the soundbar or on the box it came in.
Why your soundbar might not be getting sound even when it is connected
The most common reason a connected soundbar does not play sound is that the TV is still set to use its built-in speakers instead of the soundbar. Go to your TV's Sound settings and check the Speaker Settings or Sound Output option. Make sure the TV Speaker is turned off or the External Speaker option is selected.
Another reason is that the input on the soundbar might be set to the wrong source. If you connected the soundbar with HDMI, the soundbar should be set to HDMI input. If you used optical, it should be set to Optical input. Check the soundbar's remote or the buttons on the soundbar itself to see which input is currently selected, and switch to the one you plugged the cable into.
If you are using HDMI but the TV does not recognize the soundbar, try unplugging the HDMI cable, waiting ten seconds, and plugging it back in. Sometimes the TV needs to re-detect the device. If that does not work, try a different HDMI cable — the original cable may be damaged.
Frequently Asked Questions
Do I need a special HDMI cable for a soundbar?
No. Any standard HDMI cable works with a soundbar. You do not need to buy an expensive cable — a basic HDMI cable from any electronics store will work just as well. The only thing that matters is that it is plugged into the ARC or eARC port on your TV if you want to use just one cable.
Can I use both HDMI and optical at the same time?
You can plug both cables in, but the TV will only send sound through one of them at a time. Go to your Sound settings and choose which input you want the TV to use. Using both cables does not improve the sound — it just gives you a backup option if one cable stops working.
Why does my soundbar keep losing Bluetooth connection?
Bluetooth can drop if there is interference from other wireless devices like routers or microwaves, or if something is blocking the signal between the TV and soundbar. Move the soundbar closer to the TV or switch to HDMI or optical for a more stable connection. Bluetooth works best when the soundbar is in the same room as the TV with nothing blocking the signal.
What if my TV does not have an optical port?
Most TVs made after 2010 have an optical port, but some newer smart TVs have removed it. If your TV does not have optical, use HDMI ARC if available, or connect the soundbar with Bluetooth. You can also check if your TV has a headphone jack and use an adapter cable, though this is less common.
Do I need to turn on the soundbar every time I turn on the TV?
No. If you connect the soundbar with HDMI ARC, it will turn on automatically when you turn on the TV. With optical or Bluetooth, you may need to turn on the soundbar manually using the remote or the power button on the soundbar itself. Check your soundbar's manual to see if it has an auto-on feature.
