The simplest connection method for your Samsung soundbar
Most Samsung soundbars connect to your TV through a single cable — either HDMI or optical audio — rather than Bluetooth. This wired connection is more reliable than wireless pairing because it doesn't drop signal, doesn't require repeated reconnection, and handles the full range of sound your TV produces. If your soundbar came with an HDMI cable in the box, that's your fastest route.
The TV sends audio down that same cable to the soundbar, so you don't need to pair them separately or fiddle with Bluetooth settings. Once plugged in, the soundbar turns on when your TV turns on, and the volume controls on your remote work for both devices at once. This is why most people with Samsung soundbars never touch Bluetooth at all.
Key Takeaways
- HDMI is the best connection method if your TV has an HDMI ARC or eARC port, because it carries both picture and sound through one cable.
- Optical audio cables work on almost any TV made in the last fifteen years and are a solid second choice if HDMI ARC isn't available.
- Bluetooth is useful only for playing music from your phone or tablet, not for connecting the soundbar to your TV.
- Your TV remote will control the soundbar volume once the cable connection is made, without any pairing step needed.
- If your soundbar doesn't turn on automatically with your TV, you may need to change one setting in your TV's audio menu.
Connecting with HDMI ARC or eARC
HDMI ARC (Audio Return Channel) is the connection method Samsung recommends. Your TV has one HDMI port labeled ARC or eARC — usually HDMI 3 or 4, but check your TV's manual or the port itself for the label. Plug one end of the HDMI cable into that port and the other end into the HDMI input on the back of your soundbar.
Turn on your TV and soundbar. On your TV remote, go to Settings, then Sound, then Sound Output or Speaker Settings. You should see an option that says HDMI ARC, HDMI eARC, or External Speaker. Select it. Your TV will now send all audio to the soundbar instead of its built-in speakers. The soundbar should turn on automatically whenever your TV turns on, and your TV remote's volume buttons will control the soundbar.
If the soundbar doesn't appear in that menu, your TV may not recognize it yet. Unplug both devices, wait ten seconds, plug the TV back in first, then the soundbar. Try the Settings menu again. If it still doesn't show up, your TV's HDMI ARC port may not be active — some models require you to enable it in a separate menu under HDMI settings.
Using an optical audio cable if HDMI ARC isn't available
If your TV doesn't have HDMI ARC, or if you prefer not to use it, an optical audio cable works just as well. Look for a port on the back of your TV labeled Optical Out, S/PDIF, or TOSLINK — it's a small square port with a hinged cover. Plug the optical cable into that port and into the Optical input on the soundbar's back panel.
Go to your TV's Settings, then Sound, then Sound Output. Select Optical Out or External Speaker. Your TV will now send audio to the soundbar. Like HDMI, the soundbar will turn on with your TV and respond to your remote's volume buttons. Optical cables are less common on new TVs, but they're still found on many models made in the last ten years.
Optical cables are more fragile than HDMI — the connector is plastic and can break if bent sharply. Keep the cable as straight as possible and avoid coiling it tightly. If you notice the sound cutting out or becoming distorted, the cable may be damaged and needs replacement.
Connecting via Bluetooth for music from your phone
Bluetooth on a Samsung soundbar is meant for streaming music from your phone or tablet, not for connecting to your TV. If you want to play Spotify, YouTube Music, or podcasts through the soundbar from your phone, you'll use Bluetooth for that — but your TV audio still goes through the HDMI or optical cable.
To pair your phone, press the Bluetooth button on the soundbar's remote or the soundbar itself. The soundbar will enter pairing mode for about two minutes — you'll hear a tone or see a light blink. On your phone, go to Settings, then Bluetooth, and look for your soundbar's model number in the list of available devices. Tap it to pair. Once paired, your phone will reconnect to the soundbar automatically whenever you're in range.
If your soundbar doesn't appear in your phone's Bluetooth list, make sure it's in pairing mode. Some Samsung soundbars require you to hold the Bluetooth button for three seconds, not just tap it. Check your soundbar's manual for the exact button combination. If it still won't pair, restart both your phone and soundbar and try again.
What to do if your soundbar doesn't turn on with your TV
If you've connected the cable but the soundbar stays off until you manually power it on, your TV isn't sending the "turn on" signal. This is usually a setting called HDMI CEC, Anynet+, or Simplink — different TV brands use different names, but they all do the same thing. Go to your TV's Settings, then System or General, and look for a menu about external devices or HDMI control. Turn it on.
If you can't find that setting, try going to Settings, then Sound, and looking for an option about external speakers or audio devices. Some TVs hide the auto-power setting there instead. Once you've turned on HDMI CEC or its equivalent, unplug both devices, wait ten seconds, and plug them back in. The soundbar should now power on when your TV does.
If the soundbar still won't auto-power after that, it may not support this feature — older Samsung soundbars sometimes don't. In that case, you can buy an inexpensive smart plug and plug the soundbar into it, then set the plug to turn on when your TV turns on. This gives you the same effect without changing any settings.
Troubleshooting sound that cuts out or doesn't work
If you've connected everything but hear no sound from the soundbar, first check that your TV's audio output is actually set to the soundbar. Go back to Settings, Sound, Sound Output and confirm the soundbar is selected, not TV Speaker or Internal Speaker. If it's already selected, try selecting it again — sometimes the setting doesn't stick until you confirm it twice.
Next, check the volume. Your TV remote controls the soundbar volume once they're connected, but the soundbar itself also has a volume dial or buttons. Make sure the soundbar's volume isn't turned all the way down. You can usually see the current volume on a small display on the soundbar's front panel.
If sound cuts out randomly or only works sometimes, the cable connection may be loose. Unplug the HDMI or optical cable from both ends, wait five seconds, and plug it back in firmly. Push it in until you hear a click or feel resistance. If the problem continues, try a different cable — the original cable may be damaged inside even if it looks fine on the outside.
Connecting a Samsung soundbar without a remote
If you've lost your soundbar's remote, you can still connect it to your TV using the buttons on the soundbar itself. Most Samsung soundbars have a power button and volume buttons on the back or side. Plug in the HDMI or optical cable, turn on the soundbar with its physical power button, then go to your TV's Settings and select the soundbar as your audio output the same way you would with a remote.
To pair a phone via Bluetooth without a remote, look for a small button on the soundbar labeled Bluetooth or marked with a Bluetooth symbol. Press and hold it for three seconds until you hear a tone. Your phone should then see the soundbar in its Bluetooth list. This works the same way as using the remote's Bluetooth button.
If you want a replacement remote, Samsung sells them separately through their website or through retailers like Amazon. You'll need your soundbar's model number, which is printed on a sticker on the back or bottom of the unit.
Frequently Asked Questions
Do I need to pair my soundbar to my TV like I would with Bluetooth headphones?
No. HDMI and optical cables don't require pairing — you plug them in and the TV automatically recognizes the soundbar. Pairing is only needed if you want to play music from your phone via Bluetooth, which is separate from the TV connection.
Can I use both HDMI and optical cables at the same time?
You can plug both cables in, but your TV will only send audio through one of them. Go to Settings, Sound, Sound Output and choose which one you want to use. Using both at once won't improve sound quality — pick the one that works best for you and leave the other plugged in as a backup.
What if my TV doesn't have HDMI ARC or an optical port?
Very new TVs sometimes have only HDMI eARC, which works the same way as HDMI ARC. If your TV truly has neither HDMI ARC nor optical out, you can use a small adapter that converts one of your TV's regular HDMI ports to optical audio, though this is rare. Check your TV's manual first to confirm which ports it has.
Why does my soundbar volume change when I adjust my TV volume?
That's the correct behavior — once connected via HDMI or optical, your TV remote controls the soundbar volume directly. If you want to adjust the soundbar separately from the TV, use the soundbar's own remote or buttons instead of the TV remote.
Will connecting the soundbar affect my TV's picture quality?
No. Audio and video travel on separate paths inside the HDMI cable. Connecting a soundbar changes only the sound output, not what appears on your screen.
