Roku devices are solid streaming devices that deliver great experiences at competitive prices. The Roku TVs inherit all the perks of the Roku software like popular streaming services, voice assistants, etc. in a wide range of hardware.
But, what these streaming setups lack is a proper speaker system. That is when a soundbar kicks in. It allows users to get a greater audio experience with the Roku TVs. So how to connect the soundbar to Roku TV?
How to connect a soundbar to Roku TV?
The general method of connecting a soundbar to the Roku TV is to choose a connection that both the soundbar and the Roku TV support, then follow the easy steps below.
Choose the connection
Since the Roku TV doesn’t support Bluetooth, you can’t connect a soundbar wirelessly to your Roku TV. So wired connections are the way to go.
As mentioned, the connection you want to use should be comfortable to both the soundbar and the Roku TV. Then, head to your Roku TV, go to the input setting, and choose the connection. It could be HDMI ARC, RCA, digital optical, etc.
When using a wired connection, make sure the plug is inserted all the way through and secured in place. Otherwise, you may get one-sided audio, unsynchronized sound, or no sound.
Once you have secured your connection, you can play some sound on your Roku TV to test the sound.

The steps
Here are the general steps to connect a soundbar to a Roku TV, specifically TCL Roku TVs, but it should be similar to the Roku TVs from other hardware brands:
- Step 1: Connect the soundbar to your Roku TV with the appropriate wired connection
- Step 2: Turn on both the soundbar and the Roku TV
- Step 3: On your Roku TV, go to “Settings“, then choose “Control other devices” to enable the connection you choose.
- Step 4: On the main menu, open the system audio control, then choose and enable your connection
- Step 5: Go back to Home, the audio from the Roku TV should come out from the soundbar. Play some content with audio to test.
Connect the soundbar to your Roku TV and enable Dolby audio technology
If your soundbar supports Dolby audio technologies like Dolby Atmos, Dolby Digital, or Dolby digital plus for surround sound, you can set it to enable Dolby audio technologies and connect it to your Roku TV. When being so, your soundbar should be at D+ or DTS mode.
If you are uncertain whether your soundbar supports surround sound technologies like Dolby Digital, Dolby digital plus, or Dolby Atmos, you can look at the soundbar packaging or make a quick search online for the specifications.
Here are the steps if your soundbar supports the features to enable the capability. Note that your Roku TV must also support the same Dolby audio technologies:
- Step 1: On your Roku TV, go to “Settings”
- Step 2: Find and choose the “Audio” option
- Step 3: Set the HDMI or your chosen connection to the Dolby audio technology that the soundbar supports. Do the same for the audio mode.
- Step 4: Go back Home. The Dolby audio technologies should be enabled now.
You can further increase the audio quality of the soundbar by connecting it to a receiver, such as Yamaha or Denon brand to amplify the overall sound quality.
