The three ways to connect a soundbar to a Samsung TV
A Samsung TV connects to a soundbar in one of three ways: HDMI (the fastest and most reliable), optical cable (if your soundbar is older), or Bluetooth (wireless, but sometimes less stable). Most Samsung TVs made in the last five years support all three. HDMI is the best choice if your soundbar has an HDMI port, because it carries both picture and sound through one cable and lets the TV and soundbar talk to each other automatically.
The method you choose depends on what ports your soundbar actually has. Look at the back or side of your soundbar right now — if you see a port labeled HDMI, use that. If you see a port labeled S/PDIF or Optical (it looks like a small square hole with a light inside), use the optical cable. If neither exists, Bluetooth is your only option, though you may need to pair the devices first.
Before you start, turn off both the TV and the soundbar. This prevents connection errors and makes the pairing process cleaner. Have the soundbar remote and the TV remote within reach — you will need both.
Key Takeaways
- HDMI is the most reliable connection method and works automatically on most Samsung TVs without any setup steps.
- Optical cable is the second choice if your soundbar lacks HDMI, and it requires you to change one TV setting to enable digital sound output.
- Bluetooth works wirelessly but requires you to manually pair the devices and may drop connection more often than wired methods.
- After connecting, test the sound by playing a video or music — if you hear nothing from the soundbar, the TV audio output setting is usually the problem.
Connecting via HDMI (the easiest method)
Plug one end of an HDMI cable into the HDMI port on the back of your soundbar. Plug the other end into any HDMI port on the back of your Samsung TV — it does not matter which one. Turn on both devices and wait 10 seconds for them to recognize each other.
On your Samsung TV remote, press the Home button, then navigate to Settings (the gear icon). Go to Sound, then Sound Output. You should see an option that says HDMI or the name of your soundbar. Select it. Play a video or song to test — you should hear sound from the soundbar, not the TV speakers.
If the soundbar does not produce sound, go back to Sound Output and make sure you selected the HDMI option, not "TV Speaker". Some Samsung models call this setting "Speaker Select" instead. If you still hear nothing, unplug both devices for 30 seconds, plug them back in, and repeat the Sound Output step.
Connecting via optical cable (for older soundbars)
Plug one end of an optical cable into the optical port on your soundbar. This port is usually labeled S/PDIF or Optical and looks like a small square hole. Plug the other end into the optical port on the back of your Samsung TV — most Samsung TVs have this port, though some newer models have removed it. Turn on both devices.
On your Samsung TV remote, press Home, then go to Settings and Sound. Select Sound Output and choose Optical or S/PDIF from the list. If you do not see this option, go to Additional Settings (or informed Settings on some models) and look for Digital Audio Output. Make sure it is set to On.
Play a video to test the connection. If you hear sound from the soundbar, the connection is working. If you hear nothing, return to Sound Output and confirm you selected the optical option. Some soundbars have a small button on the back labeled Input or Source — press it to cycle through connection types until you see "Optical" or "Toslink" displayed on the soundbar's screen.
Connecting via Bluetooth (wireless option)
Turn on your soundbar and put it into pairing mode. On most soundbars, this means holding the Bluetooth button (usually marked with a Bluetooth symbol) on the remote or the soundbar itself for three to five seconds until you see a blinking light. Some soundbars display "Pairing Mode" on a small screen. Check your soundbar's manual if you are unsure — the pairing button location varies by brand.
On your Samsung TV remote, press Home and go to Settings, then Sound. Select Sound Output and look for a Bluetooth option. Select it. Your TV will search for nearby Bluetooth devices. When your soundbar appears in the list, select it. The TV will display "Connected" or a checkmark when pairing succeeds.
Play a video to test. If you hear sound from the soundbar, the connection is complete. If pairing fails, turn off the soundbar, wait 10 seconds, turn it back on, hold the Bluetooth button again, and repeat the TV search. Bluetooth connections can be finicky — if the soundbar keeps disconnecting, switch to HDMI or optical instead.
What to do if you hear sound from both the TV and the soundbar
If both devices produce sound at the same time, the TV is not sending all audio to the soundbar. Go to Settings, Sound, and Sound Output again. Make sure you selected the soundbar or HDMI option, not "TV Speaker" or "Dual Output". Select the soundbar option and confirm the change.
If the setting already shows the soundbar selected but you still hear the TV speakers, go back to Sound Output and look for an option called "TV Speaker" or "Internal Speaker". Set it to Off. This forces all sound through the soundbar only. Test again with a video.
Fixing common connection problems
If the soundbar does not appear in the Bluetooth list, make sure it is in pairing mode (the light should be blinking). If the light is solid or off, the soundbar is not ready. Hold the Bluetooth button for five seconds and try again. If the soundbar still does not appear, restart both devices — turn them off, wait 30 seconds, and turn them back on.
If you connected via HDMI or optical but hear no sound, the problem is almost always the Sound Output setting. Return to Settings, Sound, Sound Output and verify you selected the correct option. If the soundbar is listed but grayed out, unplug the cable, wait 10 seconds, and plug it back in. The TV may not have detected the connection yet.
If the soundbar connects but cuts out during videos, try lowering the volume on the TV itself (not the soundbar remote). Some Samsung TVs reduce the signal when the TV volume is very high. If cutting out continues, switch to a wired connection — HDMI or optical are more stable than Bluetooth for continuous playback.
Testing your connection and adjusting volume
After connecting, open a streaming app like Netflix or YouTube and play a video with clear dialogue. Turn up the soundbar volume using the soundbar remote — not the TV remote. The TV remote controls TV speaker volume, not the soundbar. You should hear sound clearly from the soundbar speakers, not from the TV itself.
If you want to use only the TV remote to control soundbar volume, go to Settings, Sound, and look for an option called "Remote Control" or "Universal Remote". Some Samsung models let you set the TV remote to control the soundbar volume automatically once they are connected via HDMI. This setting is not available for Bluetooth or optical connections.
Frequently Asked Questions
Do I need to pair a soundbar to my Samsung TV if I use HDMI?
No. HDMI connections work automatically — the TV recognizes the soundbar as soon as you plug in the cable and select it in Sound Output. Pairing is only required for Bluetooth connections.
Can I use both HDMI and Bluetooth at the same time?
No. Your Samsung TV can only send audio to one device at a time. Choose one connection method in Sound Output and stick with it. If you switch methods, you must change the Sound Output setting each time.
Why does my soundbar keep disconnecting from Bluetooth?
Bluetooth is less stable than wired connections, especially if other devices are nearby or if the soundbar is far from the TV. Move the soundbar closer to the TV or switch to HDMI or optical cable for a more reliable connection.
What if my Samsung TV does not have an optical port?
Newer Samsung TVs have removed the optical port. Use HDMI if your soundbar has it, or use Bluetooth. Optical cable is no longer necessary on modern TVs.
Will the soundbar work with apps like Netflix and YouTube?
Yes. Once connected and set as the Sound Output, the soundbar plays audio from any app on your TV — streaming services, cable boxes, gaming consoles, or anything else plugged into the TV.
