The fastest way: HDMI with eARC
The simplest connection uses a single HDMI cable plugged into the eARC port on your Samsung TV. eARC (enhanced Audio Return Channel) sends sound from the TV back to the soundbar through one cable, which means you do not need a separate audio cable or optical connection. Most Samsung TVs made in the last five years have an eARC port — it is usually HDMI 3 or HDMI 4, and Samsung labels it clearly on the back panel.
Plug one end of an HDMI cable into the eARC port on your TV and the other end into the HDMI eARC input on your soundbar. Power on both devices. Go to your TV's Settings menu, select Sound, then Speaker Settings, and choose the soundbar from the list. The TV will automatically detect it. You may need to turn off the TV's internal speakers in that same menu to prevent both from playing at once.
If your soundbar does not have an eARC port, use a standard HDMI cable instead, but you will also need an optical audio cable running from the TV's optical output to the soundbar's optical input. This setup works but requires two cables instead of one.
Key Takeaways
- An HDMI eARC cable is the single fastest method and requires only one cable between the TV and soundbar.
- Your Samsung TV's eARC port is usually labeled on the back panel and is typically HDMI 3 or HDMI 4.
- After plugging in the cable, go to Settings > Sound > Speaker Settings on your TV and select the soundbar from the list.
- Bluetooth connection works if your soundbar supports it, but eARC or optical audio delivers more stable sound and does not drain the soundbar's battery.
- If sound comes from both the TV and soundbar at once, disable the TV's internal speakers in the Sound settings menu.
Optical audio cable as an alternative
If your soundbar does not have HDMI eARC or you prefer a dedicated audio connection, use the optical audio cable (also called TOSLINK). Locate the optical audio output on the back of your Samsung TV — it is a small square port, usually labeled "Optical Out" or "Digital Audio Out." Plug one end of the optical cable into that port and the other end into the optical input on your soundbar.
Turn on both devices. Go to Settings > Sound > Speaker Settings on your TV and select the soundbar. The TV will route all sound through the optical connection. Optical audio is reliable and works with nearly every soundbar made in the last ten years, even older models that lack HDMI ports.
Bluetooth pairing for wireless connection
Many Samsung soundbars and TV models support Bluetooth, which eliminates the need for cables. Press the Bluetooth button on your soundbar or its remote to put it in pairing mode — most soundbars show a blinking light when ready. On your TV, go to Settings > Sound > Speaker Settings, then select Bluetooth Speaker or Bluetooth Audio Device. Your TV will scan for nearby devices and display the soundbar's name.
Select the soundbar from the list to complete pairing. Once connected, the TV will automatically send sound to the soundbar whenever you turn on the TV. Bluetooth works well for everyday watching, but it can occasionally drop the connection if something interferes with the signal, and it drains the soundbar's battery if it is not plugged in. For these reasons, a wired connection (HDMI eARC or optical) is more reliable for regular use.
What to do if the soundbar does not appear in the speaker list
If you have plugged in the cable but the soundbar does not show up in Settings > Sound > Speaker Settings, first check that both devices are powered on and the cable is fully inserted into both the TV and the soundbar. Unplug the cable from both ends, wait ten seconds, and plug it back in. Power cycle both devices by turning them off, waiting 30 seconds, and turning them back on.
If you are using HDMI eARC, make sure you plugged into the correct port — check your TV's manual or the label on the back panel to confirm which HDMI port supports eARC. If you are using optical audio, the cable should click firmly into place; a loose connection will not transmit sound. If the soundbar still does not appear after these steps, restart your TV's software by going to Settings > Support > Self Diagnosis > Reset, then try the connection again.
Adjusting volume and sound settings after connection
Once the soundbar is connected and detected, you can control its volume using your TV remote. The TV's volume buttons will adjust the soundbar's volume instead of the TV's internal speakers. If you want to use the soundbar's own remote to control volume, that usually works too — most soundbars respond to their own remote even when connected to a TV.
Check your soundbar's sound modes in its settings menu. Many soundbars have preset modes like Movie, Music, or Standard that adjust the bass and treble. You can also access these modes through your TV's sound settings if the soundbar supports it. If the sound is too quiet even at maximum volume, make sure the TV's volume is not set to a low level — the TV's volume and the soundbar's volume work together, so both need to be at reasonable levels.
Troubleshooting common connection problems
If sound comes from both the TV speakers and the soundbar at the same time, go to Settings > Sound > Speaker Settings and look for an option to disable the TV's internal speakers or set the speaker output to Soundbar Only. This prevents audio from playing through both sources.
If the soundbar cuts out or loses connection frequently, move it closer to the TV if you are using Bluetooth, or check that the cable is not bent or pinched if you are using HDMI or optical. Interference from other wireless devices can also disrupt Bluetooth — try moving the soundbar away from a microwave, wireless router, or cordless phone. If the problem persists with Bluetooth, switch to a wired connection instead.
If you hear sound from the soundbar but it is delayed compared to what you see on screen, this is called lip-sync delay. Go to Settings > Sound > informed Settings or Advanced Audio Settings (the exact name varies by TV model) and look for a Lip Sync Delay or Audio Delay option. Increase the delay in small increments — usually 50 to 100 milliseconds — until the sound matches the picture.
Connecting a soundbar to a Samsung TV with a receiver or amplifier
If you have a home theater receiver or amplifier between your TV and soundbar, the connection changes slightly. Run an HDMI eARC cable from your TV to the receiver's eARC input, then run another HDMI cable from the receiver's output to your soundbar. Alternatively, use an optical audio cable from the TV to the receiver, and let the receiver handle the connection to the soundbar.
Configure your TV to send sound to the receiver instead of directly to the soundbar. Go to Settings > Sound > Speaker Settings and select the receiver or external audio device from the list. The receiver will then route sound to the soundbar based on its own settings. This setup gives you more control over sound processing and lets you connect multiple audio devices to one receiver.
Frequently Asked Questions
Do I need a special HDMI cable for eARC?
No. Any standard HDMI cable works with eARC — you do not need to buy a cable labeled "eARC" or "HDMI 2.1." The eARC feature is built into the port itself, not the cable. A regular HDMI cable you already own will work fine.
Can I use both the soundbar and the TV speakers at the same time?
You can, but it is not recommended because the sound will be out of sync and sound muddy. Most people disable the TV's internal speakers once a soundbar is connected. If you want to use both for some reason, go to Settings > Sound > Speaker Settings and look for an option to enable both outputs, though this is rarely available on Samsung TVs.
What if my soundbar is in another room?
Bluetooth has a range of about 30 feet in open space, but walls and obstacles reduce that significantly. If your soundbar is in another room, a wired connection is not practical. Consider moving the soundbar closer to the TV, or look into a wireless audio system designed for multi-room use instead of a standard soundbar.
Will connecting a soundbar disable my TV's built-in speakers?
Not automatically. When you connect a soundbar, the TV will send sound to it, but the internal speakers may still play audio at the same time. You must manually disable the TV speakers in Settings > Sound > Speaker Settings to silence them. Look for an option called "Speaker Output," "Audio Output," or "Soundbar Only."
Is optical audio better than HDMI eARC?
HDMI eARC is faster and cleaner because it uses one cable instead of two, but both deliver the same audio quality for regular TV watching. Optical audio is more compatible with older soundbars. If your soundbar and TV both support eARC, use that. If not, optical audio works just as well.
