Some Roku TV channels have unreliable sound or the sound is spotty across all channels. Here are some troubleshooting tips if your Roku TV sound isn’t working.

Is there a problem with the sound on my TCL Roku TV?

These settings may be responsible for the sound not playing on your TCL Roku TV, but the display works fine:

• There may be a problem with the volume on your remote or it could be muted
• There is no sound coming from your speakers
• Night or Leveling is selected for the volume mode
• Using the Roku mobile app, you can listen to headphones-only

Please check the app’s support site for specifics if you are experiencing sound issues with only one app. Check that the menu volume is not disabled if the sound is missing only from the Roku menu. Navigate to Settings > Audio > Menu volume.

Your Roku TV might not be working if you do not hear any sound or see any picture.

Is there a reason why my Roku TV has lost sound?

You may lose sound on your Roku TV for a variety of reasons, including:

• A poor network connection

What to do if your Roku TV isn’t playing sound

These fixes will restore your Roku TV’s audio when your sound doesn’t work.

• You should check the volume on your remote. You can adjust the volume and mute by pressing the up and down buttons. In the event that your Roku remote is not responding, you can reset it with these steps.
• Don’t forget to turn your speakers on. Select Settings > Audio > Speakers. The TV or external speakers will not produce sound if Off is selected.
• The leveling of audio should be disabled. You can access the Options panel by pressing the Star button on your remote. The no-audio issue may be resolved by selecting Off under Volume mode.
• Roku’s mobile app allows you to turn off private listening. When you see a headphones icon on the screen, you can disable private listening by opening the Roku app and tapping on it. 
• Make sure you are connected to Wi-Fi. The quality of your audio may be affected by a poor network connection.
• You may need to update your system. Make sure your Roku TV’s OS is updated by checking its settings. The System > System Update option can be found on most Roku TVs.
• The Roku TV needs to be restarted. In the event that there is no update available, try restarting your system. Broad system issues can often be resolved by this step.
• Make sure you have all your Roku channels enabled. There’s a good chance that you’re dealing with a Roku OS or TV issue if you’re having trouble with the menu and all channels. The app developer can provide more information if it’s just one app. Otherwise, you will have to delete the channel and reinstall it.
• The HDMI and audio cables should be double-checked. If you have external accessories, like a soundbar, make sure the audio output and input connections are secure, and make sure the power cord for your Roku TV is secure. To be on the safe side, you might also want to think about replacing your cables.
• Make sure the audio settings are adjusted. Select Automatic rather than a specific audio format from System > Audio, regardless of whether you use TV speakers or a surround sound system.
  Make sure your TV speakers are disabled manually from Audio > Speakers > Off if using a S/PDIF optical connection.
• Your TV’s audio settings need to be reset. The Play/Pause button on your TV may need to be pressed three times if you have this feature. In addition, you can reset the TV audio and video settings by going to Settings > System > Advanced system settings > Factory reset.
•  Your apps won’t be deleted if you choose this option.
  The option to Reset sound settings is available on some Roku TVs under Options > Sound settings.
• You can also do a factory reset or a hard reboot. Before plugging your TV back in, turn it off and leave it unplugged for 5 to 10 minutes. The factory reset button is located on the side of the TV, or go to Settings > System > Advanced settings > Factory reset > Factory reset everything to perform the factory reset.
• To find out more about Roku TVs, contact the manufacturer. Once you’ve checked all your cables and updated and reset your Roku TV, and haven’t been able to pinpoint a problem with a particular app, it’s probably time to contact its manufacturer. Under Settings > System > About, you can find this information.

FAQ

What is the best way to connect a soundbar to a Roku TV?

Roku TV’s HDMI ARC port can be used to connect the soundbar to the TV. Roku Smart Soundbars are automatically detected by Roku TV when you set them up with your TV. CEC and ARC are enabled by going to Settings > System > Control other devices (CEC) > System audio control > 1-touch play and Control other devices (CEC) > System audio control > ARC, respectively.

Is my Bluetooth soundbar not compatible with Roku TV?

It is not possible for Roku TVs to connect directly to Roku devices via Bluetooth. Bluetooth accessories, such as phones and tablets, can only be connected to Roku devices if they have Roku Stream Bars and Roku wireless speakers set up. The Roku app allows you to turn on private listening so that you can bypass this restriction by connecting your phone to the Bluetooth soundbar.
