The fastest way: HDMI with ARC or eARC

Most Samsung TVs made in the last five years support HDMI ARC (Audio Return Channel) or the newer eARC standard. This is the simplest connection because one cable carries both picture and sound, and your TV remote often controls the sound bar's volume automatically.

Plug an HDMI cable into the HDMI port labeled ARC or eARC on your Samsung TV — usually HDMI 3 or 4, but check your manual to be sure. Connect the other end to the matching port on your sound bar. Turn on both devices, then go to your TV's Settings menu, select Sound, and choose HDMI ARC as your audio output. Your TV should recognize the sound bar within a few seconds.

If your sound bar has an eARC port and your TV supports it, use that instead of standard ARC. eARC handles newer audio formats and is more reliable, though both work with most content you watch.

Key Takeaways

  • HDMI ARC or eARC is the easiest method because one cable carries both picture and sound, and your TV remote usually controls volume.
  • Optical audio (TOSLINK) works on older Samsung TVs and sound bars but does not support newer surround sound formats.
  • Bluetooth is convenient for wireless connection but adds a slight delay and works best for TV speakers, not for gaming or movies.
  • Check your TV's manual to find which HDMI port supports ARC, as it varies by model year.
  • After connecting, always change your TV's audio output setting to the sound bar in the Sound menu — plugging in the cable alone does not activate it.

Optical audio for older TVs and sound bars

If your Samsung TV or sound bar is more than five years old, it may not have HDMI ARC. Look for a small square port labeled Optical or TOSLINK on the back of both devices. This connection uses a thin fiber optic cable and works reliably, though it does not support newer surround sound formats like Dolby Atmos.

Insert the optical cable into the port on your TV and the matching port on the sound bar. Go to your TV's Settings, select Sound, and set the audio output to Optical. The sound bar should begin playing audio within a few seconds. Optical cables are inexpensive and widely available at electronics retailers.

One limitation: optical audio does not send commands back to your TV, so your TV remote will not control the sound bar's volume. You will need the sound bar's remote or a universal remote to adjust sound.

Bluetooth connection for wireless audio

Most modern Samsung TVs and sound bars support Bluetooth, which means you can skip the cable entirely. This works well if your sound bar sits close to your TV and you do not mind a slight delay between what you see on screen and what you hear.

Put your sound bar in pairing mode — usually by holding a button on the remote or the device itself for three to five seconds until a light blinks. On your Samsung TV, go to Settings, select Sound, and choose Bluetooth Speaker. Select your sound bar from the list that appears. Once paired, your TV will connect to the sound bar automatically when you turn both on.

Bluetooth works well for everyday TV watching, but the audio delay (usually 100 to 200 milliseconds) becomes noticeable during fast action scenes or gaming. If you play video games or watch sports regularly, use HDMI ARC or optical instead.

Connecting a sound bar with a separate subwoofer

Many sound bars come with a wireless subwoofer that pairs directly to the sound bar, not to your TV. Connect the sound bar to your TV using HDMI ARC, optical, or Bluetooth as described above. The subwoofer should pair with the sound bar automatically when you power it on — look for a pairing button on the back of the subwoofer if it does not connect within 30 seconds.

If the subwoofer does not pair, check the sound bar's manual for the exact pairing steps, as the process varies by brand. Most subwoofers have a small reset button you can hold for 10 seconds to clear old pairings and start fresh. Once paired, the subwoofer and sound bar communicate wirelessly, and you only need to manage the TV-to-sound-bar connection.

Troubleshooting when your sound bar does not appear

If you plugged in an HDMI cable but hear no sound, your TV may not have switched to the sound bar automatically. Go to Settings, Sound, and manually select HDMI ARC (or Optical, or Bluetooth Speaker, depending on your connection). Some Samsung TVs default to the TV's built-in speakers even when a sound bar is connected.

For HDMI connections, make sure you used the correct port. Check your TV's manual or the back panel to confirm which HDMI port supports ARC — using the wrong port will not work. If you are still not hearing sound, try a different HDMI cable, as some cables do not support ARC properly.

For Bluetooth, if your sound bar does not appear in the list, restart both devices and try pairing again. Move the sound bar closer to the TV during pairing, as distance can prevent the connection from forming. If pairing still fails, check whether your sound bar's battery is low or whether it is already paired to another device like a phone or tablet.

When to use each connection type

Use HDMI ARC or eARC if your TV and sound bar both support it — this is the best option for most people because it is simple, reliable, and your TV remote controls the volume. Use optical audio if your devices are older or if HDMI ARC is not working. Use Bluetooth only if you want to avoid cables and do not mind a slight audio delay, or if your TV does not have HDMI ARC or optical ports.

If you own a very old Samsung TV without any of these ports, you can buy an external audio receiver or adapter, but that adds cost and complexity. In most cases, one of the three main methods above will work with your existing equipment.

Frequently Asked Questions

Why does my TV still play sound through its own speakers even though the sound bar is connected?

Your TV is set to use its built-in speakers instead of the sound bar. Go to Settings, Sound, and change the audio output to HDMI ARC, Optical, or Bluetooth Speaker depending on how you connected. You may also need to turn off the TV speakers entirely in the same menu.

Can I connect a sound bar to my Samsung TV without HDMI ARC?

Yes. You can use an optical cable, Bluetooth, or an older analog audio connection if your TV has one. HDMI ARC is the easiest method, but optical and Bluetooth both work reliably on most Samsung TVs.

Does the sound bar remote control my TV volume?

Only if you use HDMI ARC or eARC. With optical or Bluetooth, the sound bar remote controls only the sound bar's volume, not the TV's. Your TV remote will not control the sound bar's volume with optical or Bluetooth either.

What is the difference between ARC and eARC?

eARC is newer and faster, supporting advanced audio formats like Dolby Atmos. ARC works with standard surround sound. Both work with most TV content, but eARC is better if your sound bar supports it and your TV is newer than 2019.

Why is there a delay between the picture and sound with my Bluetooth connection?

Bluetooth adds a small delay, usually 100 to 200 milliseconds, because it processes audio wirelessly. This is normal and not a problem for regular TV watching, but it becomes noticeable during action scenes or gaming. Switch to HDMI ARC or optical if the delay bothers you.
