Why Is My TCL Roku TV Not Playing Sound?

If your TCL Roku tv is showing pictures but not playing sound, it indicates that the TV is working, but the sound is blocked due to any of these reasons:

  • The TV volume is muted or too low.
  • You haven’t turned on your speakers.
  • Your Roku device is in Night or Leveling volume mode.
  • The private listening feature is active.
  • The volume mode on Roku is disabled.

These might be the possible reason if Roku TV suddenly loses sound.

If you don’t hear the sound, you might need to troubleshoot why your Roku TV won’t turn on.

How Do I Know My Roku Is Having Sound Issues?

The best way to identify whether your Roku device is having sound issues is by checking if the sound problems persist when you try to play content from any Roku app. If it happens, your Roku is having sound issues. It might be due to the latest Roku OS release notes.

How to Fix Roku TV No Sound Issues

Roku sound issues could occur due to several reasons like internet failure or Wi-Fi won’t connect, corrupt cables, damaged hardware, or software glitch. Regardless of the reason, use these troubleshooting tips to solve the problem.

1. Check TV volume level and mute settings

If you had kept the volume on mute or low, the sound would be playing, but it won’t be audible. So, verify if your TV volume level is low or mute. If it is mute, press the mute button and set the volume to an audible level using your Roku remote control.

2. Check the audio and HDMI cable connections

Loosely connected or corrupt HDMI and audio cables also cause audio issues. If you are using a composite cable, check the ends of the cable to verify whether the audio connectors are correctly attached. Next, swap the HDMI cable input port and try playing a video.

Press Home on your Roku remote, Navigate to settings > Click Audio > Select Speakers and click On.

You will now hear the audio while streaming media.

Audio leveling is a Roku feature that automatically adjusts the audio levels. However, this feature may sometimes be the reason for no sound on Roku. So, you can disable it using the following method:

Play any video or music and press the star (*) button on the Roku remote > From the sound settings menu, select Volume leveling > Press the rightarrow button on the Roku remote until the option turns off.

Now, check if the sound issue has been solved or not.

5. Turn off private listening

The private listening Roku feature lets you hear the TV sound using your headphones. If you have enabled private listening, you cannot listen to the TV audio without your headphones. So, you need to disable this functionality, as explained below:

Open the Roku mobile app on your mobile device > Click the headphones icon to turn off private listening mode.

6. Check system updates

Most Roku devices fail to work correctly when an update or two is missed. You can check for updates manually and get the device updated, as mentioned below.

Press Home on your Roku remote, Go to Settings from the Roku home screen > Click System > Select System Update > Wait for the System to check for updates.

If any update is listed, click Update Now.

Try playing media from other Roku channels. If you can’t hear sound from any channels, the issue might be in your Roku device. However, if you can listen to audio on other channels, the current Roku channel might have an audio issue.

You can uninstall and reinstall the channel. If the problem persists, contact the app developer.

9. Try connecting Roku player to different input

Roku audio issues also occur when the currently selected input is not the correct input. To solve this issue, you can plug the cable into a different input on the soundbar or AVR. If that doesn’t work, replace the cable and see if the issue resolves.

10. Try changing the cable

Cables can get faulty and cause sound problems at any time. So, replace the old HDMI and audio cables with a new one. If your old cable were corrupted, this solution would work for you.

Roku offers various audio formats, and you must select the right one to hear the sound. If you are using AVR or a soundbar, you must set the audio format to Dolby Digital.

Press Home on your Roku remote, Go to the Settings page > Click Audio > Change HDMI and S/PDIF to Dolby D.

12. Your TV, AVR, or soundbar does not support the surround sound format

Only some Roku streaming sticks support surround sound using HDMI or optical cables. Make sure your TV, AVR, or soundbar supports surround sound format before playing a video.

If they don’t support surround sound, select Stereo mode from Settings > Audio > Digital Output Format > Stereo.

13. Disconnect and reconnect all cables, including the power cable

Disconnecting and reconnecting cables is one of the most working techniques to fix Roku sound problems. You must disconnect all the cables, including the power and HDMI cable, reconnect them, and follow these steps.

Go to Settings > Click Audio > Change Audio mode to Stereo > Change HDMI to PCMStereo. And you should now hear sound while streaming videos.

Instead of selecting specific Roku audio settings, you can set it to Auto using the following steps:

From the Roku Settings menu, go to System > Click Audio > Choose Audio mode and select Automatic/ Auto Detect.

15. Factory Reset your TV’s audio settings. If still not working, reset Roku

If the cables and Roku device work perfectly, reset your Roku sound audio settings to solve any unknown issues.

Go to Roku Settings > Click System > Select Advanced system settings > Click Factory Reset > Choose Reset TV audio/ picture settings.

This will reset the audio settings. You can then play a video to check if the issue has been solved.

However, if the problem stays, you can Factory reset the Roku device using the following steps:

Step 1: Repeat steps 1 to 4 as mentioned above.

Step 2: After clicking Factory Reset, select Factory reset everything.

This will reset your Roku device and restart it once the process completes.

16. Troubleshoot the audio receiver

If you tried all the steps above, chances are your Audio receiver is the culprit, not the Roku device. In that case, you should check if all the parts are switched on and the selected audio input is correct or not.

Also, try adjusting the volume levels and verify that the audio receiver is not in mute mode.

17. Contact Roku TV manufacturer

Did you try all the methods listed above but have no luck? No worries, there is still hope! You can contact Roku TV support via email or telephone, and they’ll get your problem solved.

In case of manufacturing faults, you may also get a replacement for your TCL Roku TV.
