The fastest way: HDMI with eARC

Most Sony soundbars connect to your TV using a single HDMI cable plugged into the eARC port on your TV. eARC (enhanced Audio Return Channel) sends sound from your TV back to the soundbar, so you hear everything your TV plays — streaming apps, cable, antenna — through the soundbar instead of the TV's built-in speakers. This is the simplest setup because one cable handles both the connection and the sound.

Find the HDMI port on your TV labeled eARC or ARC — it's usually HDMI 3 or HDMI 4, but check your TV's manual if you're unsure. Plug one end of an HDMI cable into that port and the other end into the HDMI input on the back of your Sony soundbar. Power on both devices. Your TV should recognize the soundbar automatically within a few seconds, and sound will route to the soundbar when you turn up the volume.

If sound doesn't come through, go into your TV's settings menu, find the audio or sound output section, and make sure it's set to send sound through HDMI eARC rather than the TV's internal speakers. The exact menu path varies by TV brand — Samsung calls it "Sound Output," LG calls it "Audio Out" — but the principle is the same.

Key Takeaways

  • HDMI eARC is the standard connection and requires only one cable from your TV's eARC port to the soundbar's HDMI input.
  • Your TV's settings menu must be set to output sound through HDMI eARC, not the internal speakers, for the soundbar to produce sound.
  • If your TV does not have eARC, you can use optical audio (TOSLINK) or Bluetooth, though these require separate setup steps.
  • Sony soundbars with subwoofers pair wirelessly to the main unit, not to your TV, so the subwoofer connection is separate from the TV connection.

Using optical audio if your TV has no eARC

Older TVs and some budget models don't have eARC. If that's your situation, use the optical audio port instead. This is a small round port on the back of your TV, sometimes labeled "Optical Out" or "TOSLINK." It carries sound from your TV to the soundbar using a thin fiber-optic cable.

Plug the optical cable into the optical port on your TV and into the optical input on the back of your Sony soundbar. Power on both devices. Go into your TV's audio settings and set the sound output to "Optical" or "S/PDIF." The soundbar should begin playing sound from your TV when ready. Optical audio works with all TV inputs — streaming apps, cable boxes, antenna — just like eARC does.

The trade-off is that optical audio carries less information than eARC, so some advanced sound formats (like Dolby Atmos) won't work. For standard stereo and basic surround sound, optical is reliable and widely supported.

Connecting via Bluetooth for wireless setup

If you want to avoid cables entirely, most Sony soundbars support Bluetooth pairing with your TV. This is useful if your TV is mounted high on a wall and running cables is inconvenient, though it's slower and less stable than a wired connection.

Put your Sony soundbar into pairing mode — usually by pressing and holding a Bluetooth button on the remote or the soundbar itself for three to five seconds until a light blinks. Then go into your TV's Bluetooth settings, scan for devices, and select your soundbar from the list. Once paired, your TV will send sound to the soundbar over Bluetooth whenever both devices are powered on.

Bluetooth works well for everyday TV watching, but it can occasionally drop the connection if the soundbar is far from the TV or if other wireless devices are nearby. If you experience stuttering or cutouts, move the soundbar closer to the TV or switch to a wired connection (HDMI eARC or optical).

Pairing a Sony subwoofer to your soundbar

If your Sony soundbar came with a separate subwoofer, it pairs wirelessly to the soundbar itself, not to your TV. The subwoofer and soundbar communicate directly, so you only need to connect the soundbar to your TV using HDMI, optical, or Bluetooth.

To pair the subwoofer, place it within six feet of the soundbar and power on both. Press the pairing button on the back of the subwoofer (usually a small recessed button you'll need a pen to press) and hold it for a few seconds. A light on the subwoofer will blink, then turn solid when pairing is complete. The subwoofer will now send low-frequency sound to match what the soundbar is playing.

If the subwoofer doesn't pair, make sure both devices are powered on, move them closer together, and try again. If pairing still fails, check your Sony soundbar's manual for the specific pairing sequence — some models use a different button or require you to press buttons in a particular order.

Adjusting volume and audio settings after connection

Once your soundbar is connected and producing sound, you can control the volume using your TV remote or the soundbar's remote. Most Sony soundbars allow you to use your TV remote to adjust volume once the connection is established — this is called HDMI CEC (Consumer Electronics Control) and it works automatically on most TVs.

If your TV remote doesn't control the soundbar volume, go into your TV's settings and look for an option called "HDMI CEC," "Anynet+," "Bravia Sync," or "EasyLink" depending on your TV brand. Turn this on, and your TV remote should then control the soundbar. If it still doesn't work, use the soundbar's dedicated remote instead.

You can also adjust bass, treble, and surround sound settings using the Sony soundbar's remote or a companion app (if your model has one). These settings are stored in the soundbar itself, so they'll stay the same even if you switch inputs or turn the soundbar off and on.

Troubleshooting when sound doesn't come through

If you've connected the soundbar but hear no sound, start by checking that the soundbar is powered on — look for a light on the front panel. Then verify that your TV's audio output is set to the soundbar, not the internal speakers. Go into your TV's audio settings and confirm the output is set to HDMI eARC, Optical, or Bluetooth (whichever connection you used).

If the soundbar is on and the TV settings are correct but you still hear nothing, try unplugging the soundbar for 30 seconds, then plugging it back in. This resets the connection and often fixes temporary glitches. If you're using HDMI eARC, also try a different HDMI cable — some cables are damaged or don't support eARC properly.

For Bluetooth connections, unpair the soundbar from your TV's Bluetooth settings and pair it again from scratch. For optical connections, make sure the cable is fully inserted into both ports and that no dust is blocking the connection.

When to call Sony support or a technician

If you've tried the steps above and the soundbar still won't produce sound, the issue may be a hardware problem with the soundbar, TV, or cable. Contact Sony's customer support with your soundbar model number (found on the back or in the manual) and a description of what you've already tried. They can walk you through additional troubleshooting or arrange a replacement if the soundbar is defective.

If you're uncomfortable opening TV settings menus or working with cables, a TV installer or home theater technician can set up the connection for you. This typically costs between $50 and $150 depending on your location and the complexity of your setup.

Frequently Asked Questions

Can I use both HDMI and optical at the same time?

No — your TV can only send sound through one output at a time. Choose one connection (HDMI eARC is best if your TV supports it) and disable the others in your TV's audio settings. If you switch between them, you'll need to change the TV's audio output setting each time.

Why does my soundbar work with some apps but not others?

Some streaming apps (like Netflix or YouTube) may have their own audio output settings that override your TV's settings. Go into the app's audio or sound settings and make sure it's set to output through your TV's speakers, not the app's internal audio. Your TV will then route that sound to the soundbar.

Do I need to update my Sony soundbar's software?

Sony occasionally releases software updates that improve performance or add features. Check your soundbar's manual or the Sony support website to see if an update is available for your model. Updates are usually installed through a USB cable or a companion app, and the manual will walk you through the process.

Can I connect my soundbar to multiple TVs?

Yes, but only one at a time. If you move the soundbar to a different room or TV, you'll need to reconnect it using the same steps. For Bluetooth, unpair from the old TV and pair with the new one. For HDMI or optical, physically move the cable to the new TV's port.

What if my TV doesn't have an eARC port?

Use optical audio instead — nearly all TVs have an optical port. If your TV has neither eARC nor optical, Bluetooth is your only option, though it's less reliable than a wired connection. Check your TV's manual to confirm which ports are available on your specific model.
