The loss of audio-video synchronization or persistent sound distortions on Onn Roku TV may be the result of misconfigured audio settings, power issues, or channel problems.

Onn Roku TV Sound Distorted – 6 Proven Ways to Fix!

Tip: Have you tried rebooting the onn Roku TV using the remote control and built-in button?

1. Test a Different Streaming Channel

Roku channels can be referred to as “channels,” since the Roku home screen closely replicates the channel guide of a regular TV.

So, the first step is to determine whether the sound distortion occurs on several channels and whether it has something to do with what’s streaming currently.

Cycling through channels on your onn Roku TV is possible by pressing the “Home” button on the remote control and highlighting the channel you wish to watch before pressing “OK.”

Then, the TV should automatically switch to the selected channel (application) and start streaming.

How to Check Volume/Mute Status On Onn Roku TV?

Before proceeding further, it’s also recommended to check if the onn Roku TV has been muted or the volume has been lowered to a minimum.

You can check the status of both the mute and volume status by pressing the “Volume” and “Mute” buttons on the Roku remote respectively.

Note: Verify the TV’s volume is set at 30–40% to prevent premodulation!

2. Adjust Onn Roku TV Audio Settings

So, misconfigured audio settings are the next possible reason why the onn Roku TV sound distorted.

Assigning too high/low values for the TV’s speech clarity, volume modes, treble/bass could potentially lead to persistent TV sound disruptions or distortions, regardless of the media.

First, let’s learn how to access the TV’s audio settings!

2.1 How to Access the Onn Roku TV Audio Settings?

1. Access one of the installed Roku channels on your TV.
2. Press the star (*) button on the Roku remote control.
3. Go to “Advanced sound settings” or “Sound settings.”
4. Scroll downwards in the tab to find all available options.

Tip: The audio settings can also be configured through the Roku mobile application!

2.2 What’s the Meaning of the Roku Audio Options?

The Onn Roku TV sound menu consists of the following settings:

• [Speech clarity] options: Adjusting this option boosts dialogue content in relation to the other mixture of sounds.

• [Volume mode] options: Pick an equalizer preset for the audio output of the onn Roku TV.

• [Treble] options: Adjust the “higher frequencies” of the TV’s output for a more detailed sound or lower them for a softer sound.

• [Bass] options: As the name suggests, increasing this option boosts the bass, while decreasing it, lowers it.

Note: Ensure the onn Roku TV is updated to the most current OS versions if one or more of the options are missing.

2.3 How to Adjust Onn Roku TV Audio Settings?

Here’s how to adjust the audio options to eliminate the sound distortions:

• Speech clarity: Set the feature to “Off” or “Low” for best optimization.

• Volume mode: Set the feature to “Standard” or “Music” for best effects.

• Treble: Set the feature to the middle section of the slider.

• Bass: Set the feature to the lower section of the slider.

Note: It’s recommended to test the audio settings on each possible value to determine if there’s a significant impact on the volume and whether the distortion persists.

3. Troubleshoot the TV’s Power Supply

Persistent problems with the sound can be emerging because of an underlying power supply issue with the onn Roku TV.

There’s a lineup of things to try that would certainly improve the functionality of the onn Roku TV’s power supply and eliminate problems with the audio output.

So, let’s begin with the simplest step – a power cycle.

Step #1 Power Cycle the Onn Roku TV

The power cycle involves suspending the TV’s power supply continuously until all of the residue electricity has drained. 

To begin, press the “Power” button on the remote control and unplug the TV’s power adapter for a duration of 60 seconds.

Step #2 Plug to a Different A/C Outlet

The power outlet is the main culprit when it comes to inconsistencies with the power supply.

If the power cycle had little to no effect, plug the onn Roku TV into a proven wall outlet and check if there’s a malfunction with the current one. 

Step #3 Remove Third-Party Equipment

Last but not least, it is important to ensure that no third-party equipment could interfere with the TV’s power supply.

Temporarily remove all types of power strips, dividers, smart plugs, cord extenders, and other appliances present in the setup of your onn Roku TV. 

Note: The main symptoms of inconsistent power supply are rebooting, shutting off, and possibly a black screen.

4. Inspect the TV’s Cable Connections

A fault with the TV cables can potentially be another reason for onn Roku TV sound problems! 

Well, connecting third-party devices over HDMI, Optical, or audio cables can disrupt the output of the TV, especially if you have specified the connected device as the default output.

How to Identify a Cable Connection Fault?

First, verify the external device’s video/audio cable is secured on the back of your onn Roku TV, as well as the other input.

Check whether there’s visual damage on the cable and if possible, test the cable on an alternative device to determine if there will be any issues.

It’s also recommended to connect the external device to a different available port on the back of your onn Roku TV to test if that will address the disruptions in the audio. 

If nothing helps, unplug all third-party devices from the back of your TV and test! 

Tip: Change the TV’s audio output to “TV Speakers” at “Settings” → “Audio” → “Audio output” after all external devices are disconnected. 

5. Update the Problematic Roku Channel/s

As established, the audio distortions for most users occur while viewing a single or a handful of channels on the onn Roku TV.

An outdated firmware version of the channel can be the cause of a variety of issues with the functionality, including audio distortions while viewing it.

Here’s how to update a channel on your onn Roku TV:

1. Press the “Home” button on the onn Roku TV remote.
2. Highlight the channel from the screen that causes issues.
3. Next, press the star (*) button on the TV’s remote control.

5. Wait until the OS check finishes and repeat for other apps.

Notice: The onn Roku TV must have a stable internet connection in order to update channels!
