The fastest way: HDMI with eARC

The simplest connection uses a single HDMI cable and works on most Samsung TVs made in the last five years. Plug one end of an HDMI cable into the eARC port on your Samsung TV (usually HDMI 3 or 4, marked with "eARC" on the back panel) and the other end into the eARC port on your soundbar. That's the whole physical setup.

Once plugged in, turn on both devices and go to your TV's Settings menu. Navigate to Sound > Sound Output and select your soundbar from the list. The TV will automatically send audio to the soundbar instead of its built-in speakers. You won't need to pair anything else or adjust volume separately—your TV remote controls both.

eARC means the TV and soundbar can talk to each other in both directions. The TV sends audio to the soundbar, and the soundbar can send information back about what it's receiving. This is why it's the most reliable method and why Samsung recommends it.

Key Takeaways

  • HDMI eARC is the fastest setup: plug a cable into matching eARC ports, then select the soundbar in your TV's Sound Output menu.
  • If your soundbar or TV lacks eARC, use a regular HDMI cable into any HDMI port, but you may need to manually switch audio output.
  • Bluetooth works for older soundbars or as a backup, but requires pairing and may drop connection if the soundbar moves far from the TV.
  • Optical audio (TOSLINK) is an older wired option that still works on many Samsung TVs and soundbars without HDMI ports.
  • Once connected, test with a streaming app or TV channel to confirm sound is coming from the soundbar, not the TV speakers.

HDMI without eARC: when your devices don't have matching ports

If your TV or soundbar doesn't have an eARC port, use a standard HDMI cable instead. Plug it into any available HDMI port on both devices. The connection will work, but the TV won't automatically detect the soundbar the way it does with eARC.

Go to Settings > Sound > Sound Output and look for your soundbar in the list. If it doesn't appear, your TV may not recognize it yet. Power off both devices, wait 30 seconds, and power them back on in this order: soundbar first, then TV. This forces them to communicate during startup.

One limitation: without eARC, your soundbar may not receive audio from all sources. Streaming apps, cable boxes, and game consoles connected to the TV should work, but some older Samsung TVs won't send audio through a non-eARC HDMI port. If sound doesn't come through after setup, try the optical audio method instead.

Bluetooth: wireless pairing for soundbars without HDMI

Bluetooth works on nearly every soundbar and Samsung TV, even older models. Put your soundbar in pairing mode—usually by holding a button on the remote or the soundbar itself for three seconds until a light blinks. On your TV, go to Settings > Sound > Sound Output, select Bluetooth, and choose your soundbar's name from the list.

Bluetooth is convenient because there are no cables to run, but it has two real drawbacks. First, the connection can drop if the soundbar moves more than 30 feet from the TV or if something blocks the signal. Second, Bluetooth adds a slight delay to the audio, which you'll notice during movies or games—the sound won't quite match the picture.

Use Bluetooth as a backup method or if your soundbar has no HDMI port. For daily watching, HDMI eARC or optical audio will feel more responsive and stable.

Optical audio (TOSLINK): the wired alternative

If your soundbar has a TOSLINK port (a small square opening, usually labeled "Optical In"), you can connect it with an optical audio cable instead of HDMI. Plug one end into the optical port on your Samsung TV's back panel and the other into your soundbar. Optical cables are inexpensive and widely available.

Go to Settings > Sound > Sound Output and select Optical. The TV will send audio through the cable to the soundbar. Optical audio is reliable and has been standard on Samsung TVs for over a decade, so it works on older models that lack HDMI eARC.

The trade-off is that optical audio only carries stereo sound or basic surround formats—it won't handle newer audio types like Dolby Atmos or DTS:X. If your soundbar supports those formats and you want to use them, HDMI eARC is the better choice.

What to do if your soundbar doesn't appear in the Sound Output menu

If you've plugged everything in but the soundbar isn't showing up, start by checking the cable itself. Unplug it from both ends, wait 10 seconds, and plug it back in firmly. Make sure you're using the correct port—eARC ports are usually labeled on the TV's back panel, and optical ports are small square openings, not round audio jacks.

Next, restart both devices. Power off your TV completely (not just standby), wait 30 seconds, then power it back on. Do the same with the soundbar. Many connection issues clear up after a full restart because the devices didn't complete their handshake the first time.

If the soundbar still doesn't appear, check your TV's manual or Samsung's support website for your specific model number. Some older Samsung TVs require you to enable audio output in a separate menu before the soundbar will show up. Your soundbar's manual should also list which connection types it supports—if you're using HDMI but the soundbar only has optical, that's why it's not being recognized.

Testing your connection and adjusting volume

Once your soundbar appears in the Sound Output menu and you've selected it, open any app with sound—Netflix, YouTube, or a live TV channel. Turn up the volume on your TV remote and listen. If sound comes from the soundbar and not from the TV's built-in speakers, you're connected correctly.

If you hear sound from both the TV and the soundbar, go back to Settings > Sound and look for an option called "TV Speaker" or "Internal Speaker." Turn it off. This prevents the TV from playing audio through its own speakers while the soundbar is active.

Some Samsung TVs let you control the soundbar's volume directly from the TV remote once it's connected via HDMI eARC or optical. If your remote doesn't control the soundbar volume, use the soundbar's own remote or its app instead. You can usually set the soundbar to a fixed volume and then adjust everything through the TV remote.

When to call Samsung support or the soundbar manufacturer

If you've tried all the steps above and the soundbar still won't connect or produce sound, the issue is likely a hardware problem rather than a setup mistake. A faulty HDMI port, a damaged cable, or a soundbar that needs a firmware update can all prevent connection.

Before contacting support, write down your TV's model number (found on the back panel or in Settings > About TV) and your soundbar's model number. Have the cable type you're using ready to mention. Samsung support can walk you through model-specific troubleshooting, and the soundbar manufacturer can tell you if a firmware update is available.

If the soundbar is new and still under warranty, a replacement cable or device swap is often faster than troubleshooting. Keep your receipt and original packaging in case you need to return it.

Frequently Asked Questions

Do I need a special HDMI cable for eARC?

No. Any standard HDMI cable works with eARC. You don't need to buy "eARC cables" or premium versions. The eARC feature is built into the ports themselves, not the cable. A cable that cost $5 works the same as one that cost $50.

Can I use both the TV speakers and the soundbar at the same time?

You can, but it's not recommended. If you want sound from both, go to Settings > Sound and turn the TV Speaker back on while the soundbar is selected. You'll hear audio from both, but the slight delay in the soundbar will make them sound out of sync. Most people turn off the TV speaker entirely once the soundbar is connected.

Why does my soundbar only work with the TV remote and not with other devices?

When connected via HDMI eARC or optical, the soundbar receives audio only from your TV. If you want to use the soundbar with a cable box, game console, or streaming device, connect those devices to the TV first, then the TV sends the audio to the soundbar. The soundbar doesn't need its own connections to everything else.

Is there a way to connect a soundbar without any cables?

Yes, Bluetooth is completely wireless. Put the soundbar in pairing mode, go to Settings > Sound > Sound Output, select Bluetooth, and choose your soundbar. The downside is that Bluetooth can drop connection if the soundbar moves far from the TV, and it adds a slight audio delay that you'll notice during movies.

What if my soundbar is older and doesn't have HDMI?

Older soundbars usually have optical audio (TOSLINK) ports. Use an optical cable from your TV's optical port to the soundbar's optical input, then select Optical in your TV's Sound Output menu. If your soundbar has neither HDMI nor optical, Bluetooth is your only wired-free option.
