How to Connect a Soundbar to TCL Roku TV

How to Connect a Soundbar to a TCL Roku TV

Hooking up a soundbar to a TCL Roku TV is not that different from connecting a soundbar to another TV brand. While it’s easy if you have the right components, it can still be confusing for some of us. So, we’ve made this guide to show you how.

How To Connect

The first thing you need to do is to figure out which form of connection you want to use. It needs to be one that is compatible with both devices, meaning both your TV and your soundbar would need the same connection.

Once you have the proper connections, you can turn on your TV and look for the right settings. Go into settings (input) and choose the connection you have (HDMI ARC, digital optical, RCA, etc.).

Ensure that all the inputs are pushed all the way in and are completely secure. If not, this could lead to one-sided audio, severe lag, or even no sound at all. 

Once all the connections have been secured and double-checked, you can then test the sound. Turn on the TV, play your favorite movie, and wait for the impressive sound to come out of your excellent soundbar.

Since most televisions nowadays are smart TVs, the setup and settings should be quite straightforward. To make things easier, we have condensed the process into a few simple steps:

  1. Connect the soundbar to the TCL Roku TV
  2. Turn on both devices
  3. Turn on “settings” on your TV
  4. Click on “control other devices”
  5. Enable the connection you chose
  6. Pull up the system audio control on the main menu
  7. Enable the connection you chose
  8. Return to Home. The soundbar should be working now.

There are additional considerations if you want to connect your soundbar to a receiver.

Setting For The Ideal Performance

If your soundbar is equipped with Dolby technology, you can set it to enable surround sound audio. Simply set the device to Dolby D+ or DTS mode and you’ll get the best sound setting your device can offer.

Now, you may not be sure if your soundbar offers high-quality surround sound audio. Dolby Digital, Dolby Atmos and DTS technology [1] are the ones that grace home systems and mimic the way a theater sound system works. You can check if your soundbar has it by looking at any labels in the box or doing a quick online search.

If your soundbar is capable of decoding this type of audio (just like these cheap Dolby Atmos soundbars), follow these steps to enable this capability:

  1. Go to “settings” on your TCL Roku TV
  2. Choose “audio”
  3. Set the HDMI option or whichever connection to one of the above surround sound technologies
  4. Then do the same in “audio mode”
  5. Return to your home screen and enjoy surround sound!

Once your soundbar is connected to your Roku TV, it will significantly enhance the sound produced by the TV speakers. This will improve your viewing experience, especially since surround sound is now the standard for entertainment.

With the right soundbar connection and settings in place, you’ll be able to experience sound in a more realistic manner. Of course, connecting your soundbar to a receiver either Denon or Yamaha brand can amplify the overall sound quality.  So the next time you’re watching a movie, you’ll feel as though you’re part of the action instead of just watching from the outside.


What soundbars work with TCL Roku TV?

Soundbars that work with the TCL Roku TV include the Sonos Beam, Bose soundbar, Polk soundbar, Yamaha Yas-207 and of course, the soundbar of the same brand, the TCL Alto. Generally, most soundbars are compatible with the Roku TV, so it’s not hard to find one.

How do I connect my soundbar to my TCL Roku TV with an optical cable?

Connect your soundbar to your TCL Roku TV by plugging in the optical cable into the corresponding ports on both devices. The input and output should be clearly labeled on the back of both.

How do I connect my soundbar to my TCL Roku TV without HDMI?

Connect your soundbar to your TCL Roku TV with digital optical, analog, RCA or 3.5mm cables. Digital connections are generally better than analog ones because they are able to process and decode better sound. For surround sound, you definitely need digital.

Can I connect a Bluetooth soundbar to my TCL Roku TV?

No, you cannot connect a Bluetooth device to the TV itself. You can only pair Bluetooth devices if you use the TCL Roku wireless speakers or the smart soundbar. To connect to the TCL Roku TV, you would still need a wired connection.


Connecting a soundbar to a TCL Roku TV isn’t that different than other brands. While it offers a number of wired setup options, wireless connection to your Roku TV can only be achieved via connection through other devices. For wired connections, we would recommend digital over analog for better sound.

Overall, connecting a soundbar to a Roku TV isn’t that complicated. Just follow our steps closely for an easy setup.

Sometimes, sound quality coming out of your device depends on its position. Get help on how to mount your soundbar for optimum experience, next!
