How to Fix Onn Roku TV Sound Not Working??

Besides different methods, the solution requires an inspection of your setup that we’ve included in chronological order below.

It’s recommended not to skip any of the solutions!

Solution #1 Increase Volume Unmute

The first thing that you should check that can be related to lack of sound on your Roku TV is the TV’s volume and mute status. 

The following reasons can be responsible for the audio loss:

• The TV is muted.
• The TV’s volume has been lowered to a minimum.

Let’s first increase your TV’s volume to check if that will resolve the problem:

How To Increase Onn Roku TV Volume?

Take your Onn Roku TV remote and point it towards the TV. Press the volume + button 10-15 times.

If the volume has been lowered to the minimum, this should make it audible enough for you to notice the change.

Also, observe the volume level indicator icon.

How To Unmute Onn Roku TV?

Once again, point the remote towards the TV and press the mute button, located near the volume buttons.

You will notice a mute icon that will appear. Make sure that it is not red hence, your TV is unmuted.

Note: While working with the remote, make sure that your Onn Roku TV is playing something that has audio.

Solution #2 Play From a Different Source

Chances are that the current TV show, music, or platform doesn’t have sound.

If that’s the case, you should switch to an alternative broadcast or source of media and check if the audio is going to appear there.

You can attempt it on platforms such as YouTube, Netflix, Hulu, Spotify, or whatever is available on your TV.

If it is a music player app, it will most likely have a volume controller on its own. Make sure that the audio is increased from there also.

Tip: You can also turn on recorded and save media playback that has audio to be more confident while testing.

Solution #3 Hard Reset Your TV

If there’s a software-related problem with your Onn Roku TV, the best way to solve the issue is to perform a hard reset.

This will discharge the device, reset ALL services and hopefully, that would bring back the audio. 

Here’s how to hard reset your TV in easy steps:

1. Turn OFF your Onn Roku TV using the remote.
2. Wait for 60 seconds.
3. Unplug the TV from the power source.
4. Stand by for another 5 minutes.
5. Reconnect the TV after 5 minutes and check if the problem is solved.

Note: Make sure to keep your TV disconnected for at least 5 minutes. Otherwise, the hard reset won’t work as intended.

Solution #4 Disable Audio Leveling

If you have this feature enabled on your Onn Roku TV, it may cause the device to lose sound every now and then.

Audio leveling is used to automatically adjust the volume to a fixed level while watching a TV channel or broadcast. 

It’s really effective for occasions when the sound of the commercials feels a lot louder than the actual volume of the program.

Other times, it could deceive us into thinking that there is a problem with the audio.

To disable audio leveling, follow these instructions:

1. Press the Start button on your Onn Roku TV remote.
2. Go to the options panel.
3. Go to “Volume Mode”.
4. Now highlight the “OFF” option that you see on the screen.
5. Press the “OK” button on your remote to disable the audio leveling feature.
6. Check if your TV is going to have sound now.

Tip: This feature doesn’t certainly ruin your TV’s sound every time. You can enable it for channels that have unbalanced volume levels.

Solution #5 Update Your Roku System

Many users recently reported that updating your Onn Roku TV system may fix audio issues long-term.

Outdated software versions are already getting out of support and this can cause complications with the volume and the audio of your TV.

Follow these instructions to update your Onn Roku TV system:

1. On your remote, press the Home button.
2. Go to Settings.
3. Press the “System” tab.
4. Head over to “System Update”.
5. Choose “Check Now” to perform a manual check for updates.
6. Install an update with the most recent release date.

Note: You can view the current software build and release date at the “Update” menu before pressing “Check Now”.

Solution #6 Disconnect Third-Party Speakers

Another cause for the Onn Roku TV sound, not the working problem could be third-party speaker devices that are connected to the television.

Disconnect any third-party speaker devices! 

Your Onn Roku TV has the ability to automatically switch to the default output device so you shouldn’t worry about the settings.

Unplug everything and test.

Third-party devices that can mess with the volume can be one of the following:

• Speakers with AUX connectors.
• Home theaters with splitters.
• Wireless-Bluetooth speakers.
• Soundbars.

Make sure that your TV is clear of any of those devices and check the default output.

Notice: Keep all third-party sound devices disconnected until the end of this guide or until the problem with the audio is resolved.

Solution #7 Reset Your TV To Factory Defaults

Instead of bothering with each setting that can make the sound go away individually, you should reset your TV back to factory defaults.

If this problem is software-related, a factory reset is most likely to resolve the problem.

Here’s how to reset your Onn Roku TV back to its factory defaults:

1. Grab hold of your Roku remote.
2. Press the Home button.
3. Select the “System” tab.
4. Head to “Advanced system settings” in the same tab.
5. Choose “Factory reset” from the available options.
6. Choose “Factory reset everything” once again, from the list of available functions.
7. Confirm that you want your TV to undergo a complete software reset.
8. Wait for the device to erase everything and reboot.

If a factory reset didn’t solve the audio problem with your Onn Roku TV, it’s strongly suggested to consult with customer service for further help.

Perhaps this would be your chance to put your warranty into use.

Note: Do not unplug your TV while it is resetting, since this can further complicate the software issues.
