The fastest way: HDMI eARC or optical cable
Most Samsung soundbars connect to Samsung TVs through a single cable rather than Bluetooth. The TV sends audio through an HDMI eARC port (enhanced audio return channel) or a digital optical port, and the soundbar receives it. This is faster and more reliable than Bluetooth because the cable carries a dedicated audio signal that does not compete with other wireless devices in your home.
If your TV and soundbar both have HDMI eARC ports — usually labeled eARC or ARC on the back — use an HDMI cable between them. This single cable handles both video and audio, and it is the method Samsung recommends. If your TV has an optical port but no eARC, use a digital optical cable instead. Both methods work without pairing or setup beyond plugging in the cable.
After you connect the cable, turn on both devices and check your TV's sound settings to confirm the audio is routing to the soundbar. On most Samsung TVs, go to Settings > Sound > Sound Output and select the soundbar from the list. The TV will remember this choice.
Key Takeaways
- HDMI eARC is the preferred connection method because one cable carries both video and audio, with no pairing required.
- Digital optical cable is the backup option if your TV lacks eARC but has an optical port.
- Bluetooth works as a fallback for older soundbars or when cables are not practical, but it is slower and can drop connection.
- After connecting the cable, change your TV's Sound Output setting to route audio to the soundbar instead of the TV speakers.
- If the soundbar does not appear in your TV's sound menu, restart both devices and check that the cable is fully inserted.
When to use Bluetooth instead
Bluetooth is useful only if your soundbar is far from the TV or if running a cable is not practical. Samsung soundbars that support Bluetooth will enter pairing mode when you hold the Bluetooth button on the remote for a few seconds — usually the button has a Bluetooth symbol. On your TV, go to Settings > Sound > Bluetooth Speaker List and select the soundbar from the devices shown. The TV and soundbar will pair and remember each other.
Bluetooth pairing is one-time setup, but the connection itself is less stable than a cable. Audio can lag slightly, especially if other Bluetooth devices are nearby, and the connection may drop if you move the soundbar or TV. For everyday use, a cable is more reliable.
Checking your TV and soundbar ports
Before you buy a cable, look at the back of both your TV and soundbar to see which ports they have. Samsung TVs typically have one or both of these: an HDMI port labeled eARC or ARC (usually HDMI 3 or 4), and a round digital optical port. Soundbars have the same ports on the back or side.
If your TV is older than five years, it may not have eARC — in that case, check for the optical port on both devices. If your soundbar is very old, it might only have Bluetooth or a 3.5mm headphone jack, which means you will need to use Bluetooth or a different connection method. Check your soundbar's manual or the label on the back to confirm which ports it has.
Setting up HDMI eARC step by step
Connect an HDMI cable from the eARC port on your TV to the eARC port on your soundbar. Both ports are usually labeled, but if you are unsure, check the manual that came with each device — the port number is printed there.
Turn on both the TV and soundbar. On your TV remote, press the Home button, then go to Settings > Sound > Sound Output. You should see the soundbar listed as an option. Select it. If the soundbar does not appear, turn both devices off, wait 30 seconds, and turn them back on.
Test the connection by playing something on your TV — a streaming app, a broadcast channel, or a movie. You should hear sound from the soundbar, not from the TV speakers. If you hear sound from both, go back to Sound Output and make sure the soundbar is selected.
Setting up digital optical cable
If your TV does not have eARC, use a digital optical cable instead. These cables are inexpensive and look like a thin black cord with a small rectangular connector on each end. Connect one end to the optical port on your TV and the other to the optical port on your soundbar.
Turn on both devices. On your TV, go to Settings > Sound > Sound Output and select the soundbar. If it does not appear, restart both devices and try again. Optical cables work the same way as eARC — once you select the soundbar in your TV's sound menu, all audio from the TV will play through it.
Troubleshooting when the soundbar does not show up
If the soundbar does not appear in your TV's Sound Output menu, first check that the cable is fully inserted into both ports. Push it in firmly until you hear or feel a click. Then restart both devices: turn them off, wait 30 seconds, and turn them back on.
If the soundbar still does not appear, try a different HDMI cable or optical cable. Some cables are defective or damaged, and swapping it out is the fastest way to rule that out. If a different cable works, the original cable is the problem.
If the cable is definitely connected and a different cable does not help, check your TV's software version. Go to Settings > Support > Software Update and see if an update is available. Older TV software sometimes does not recognize newer soundbars. After updating, restart both devices and try again.
Why the soundbar is better than TV speakers
A soundbar has larger speakers and more power than a TV, so dialogue is clearer and bass is deeper. When you watch a show or movie, you hear voices and music the way the creators intended. TV speakers are designed to be thin and fit inside a flat screen, which means they sacrifice sound quality.
A soundbar also sits at ear level when you are sitting on your couch, so sound reaches you directly instead of bouncing off the wall behind the TV. This makes a noticeable difference in how natural dialogue sounds and how immersive action scenes feel.
Frequently Asked Questions
Do I need to pair my Samsung soundbar to my TV if I use a cable?
No. HDMI eARC and optical cables do not require pairing. You plug in the cable, select the soundbar in your TV's Sound Output menu, and you are done. Pairing is only needed for Bluetooth.
Can I use both a cable and Bluetooth at the same time?
No. Your TV will send audio through whichever connection you selected in the Sound Output menu. If you want to switch from cable to Bluetooth, you have to go back to Settings and change it manually.
What if my soundbar is in a different room from my TV?
Bluetooth can work at a distance of about 30 feet in open space, but walls and obstacles reduce that range. If your soundbar is in another room, Bluetooth may not be reliable. A cable is not practical either, so consider moving the soundbar closer to the TV or using a different audio solution.
Why does my soundbar keep disconnecting from my TV?
If you are using Bluetooth, interference from other wireless devices can cause drops. Move the soundbar closer to the TV, turn off other Bluetooth devices nearby, or switch to a cable connection. If you are using a cable and the connection drops, the cable may be loose or damaged — push it in firmly or try a different cable.
Do I need to change any settings on the soundbar itself?
Most Samsung soundbars work automatically once connected. Check the soundbar's remote or manual to see if there is an input or source button you need to press, but usually the TV handles all the settings through the Sound Output menu.
