Onn Roku TV Sound Distorted – 9 Working Solutions

Solution #1: Power Cycle Your TV

One of the simplest ways of solving the Roku sound distortion is to power cycle your TV. It may go overlooked by some users, and thus we are listing it as the first troubleshooting step. 

Here you go:

1. Unplug the TV from power while it is on;
2. Wait a few minutes;
3. Plug it back into power;
4. Turn the TV on.

Restart The System

Similarly, you can restart the Roku system by navigating through some options. The effectiveness should equal that of power cycling.

1. Press the “Home” button on the remote;
2. Select “System”;
3. Go to “System Restart”;
4. Choose “Restart” and confirm.

Solution #2: Clear The TV Cache

Even though sound issues can have multiple causes, we should not overlook the device’s storage. And here, we will tackle the TV cache specifically.

When the system builds too much cache, some functions will start slowing down or working weirdly.

1. Press the Home button on the TV remote;
2. Hover the cursor over the “Home” option on the screen;
3. Press the “Home” button again, but five times consecutively;
4. Press the “Up” button;
5. Press “Rewind” twice;
6. Press “Fast forward” twice.

After clearing the cache, restart the TV and check if the audio distortion has been fixed.

Solution #3: Examine The Cables

In scenarios where a streaming device interfaces with a TV or when the TV transmits audio to an external soundbar or similar audio equipment, the culprit could be the audio cables. 

In light of this, we recommend the following guidelines to address the issue:

Step#1. Begin by meticulously inspecting and ensuring a robust attachment of the audio cable to both ends. A secure connection is crucial for accurate data transmission between the devices.

Step#2. Detach the audio cable from both ends and visually examine the presence of dust or debris. If found, carefully remove any particles that might impede the signal quality, then securely reconnect the cable.

Step#3. Consider substituting the existing cable with another one of the same type if available. This step is valuable in eliminating the possibility of a faulty cable causing sound distortion.

Step#4. For individuals utilizing soundbars with multiple audio inputs, attempt connecting the cable to a different input option. This action aims to ascertain whether the issue lies within a specific input source.

By methodically performing these steps, you can effectively diagnose and potentially resolve sound distortion issues stemming from inadequate connections between audio ports.

Solution #4: Check The Audio Settings

As a tech expert, it’s important to troubleshoot and optimize the audio settings for your Onn TV to resolve any sound-related issues.

Here’s a step-by-step guide to configuring the audio settings correctly for your Onn Roku TV:

If You Have A Roku Soundbar

For Onn Roku TVs connected to a Roku soundbar or A/V receiver using an optical (TOSLink) cable, follow these steps:

1. Press the Home button.
2. Navigate to the Settings menu, then select Audio.
3. Change the audio output from HDMI and S/PDIF to Dolby Digital (Dolby D).

If the situation includes HDMI, proceed with the following instructions:

1. Turn on your Roku TV and use the remote to press the Home button.
2. Go to Settings and select Audio.
3. Adjust the Audio mode to Stereo.
4. Set the HDMI audio output to PCM-Stereo.

Disable Volume Mode

There is another setting on your Onn Roku TV that might cause sound distortion. Such a setting is the volume mode, and you can adjust it by doing this:

1. Press the “*” button on the remote;
2. Go to the Sound Settings;
3. Locate the “Volume mode” option;
4. Toggle it off.

Solution #5: Equalize The Audio

Sometimes the audio distortion on any TV, including your Onn Roku TV, is caused by the audio being badly equalized. 

Fortunately, fixing that is very easy:

1. Open the TV’s settings;
2. Go to the sound/audio settings;
3. Locate the Equalizer;
4. Choose “Reset to default” or anything similar.

Once the audio equalization is set to default, any sound issues should be gone. If that isn’t fixed, you might also try tweaking the frequency yourself. 

Note: Only remember to adjust audio equalization very carefully, as doing it in a sloppy 

manner can result in greater audio trouble.

Solution #6: Adjust The Refresh Rate

Some video settings can also cause interference in the audio processing, leading to audio distortion. Sometimes the audio and video might also get out of sync. 

So what we will do here is adjust the refresh rate:

1. Press the remote’s Home button;
2. Go to “Settings”;
3. Select “System”;
4. Select “Advanced system settings”;
5. Go to “Advanced display settings”;
6. Find “Auto-adjust display refresh rate” and set it to “disabled.”

If the steps above don’t make any difference, you might want to keep the option enabled.

After all, disabling it might cause a bad experience when watching movies and other shows.

Solution #7: Check Your Network

If the issue doesn’t lie in the cables or the TV’s settings, we can next take a look at the network’s possible part in the issue. First, restart your router while also restarting the TV.

If that doesn’t work, do the following:

• Ensure that the router is close to the TV so it receives enough data and the transmission doesn’t flicker;
• Go to the TV’s network settings and ensure that the device is connected to the 5GHz frequency;
• Check whether there are other devices in the environment that could lead to data diversion and interference;
• Reset the network settings by erasing the current Wi-Fi data and adding the network credentials again;
• If possible, connect the router and TV via Ethernet.

Tip: You could also try leaving the TV disconnected from the network and try watching live TV. 

Then you can test if the issue is network-related. 

Solution #8: Update The TV

Reaching the end of the article, we should turn our attention to software-changing solutions.

The first of them is updating your Roku system. Perhaps the lack of some recent fixes has caused the audio to malfunction. 

Here is what you will do:

1. Locate the TV’s Settings;
2. Select the “System” menu;
3. Head to “System Update”;
4. Choose “Check Now”;

If an update is truly available, you will be able to download it. Shortly after installation, check if the audio issue has been solved.

Solution #9: Reset The TV

It is also possible that no update is available for your TV, but the issue persists. In that case, we recommend you try and reset the device.

Just remember that resetting entails getting rid of all your files, shows, apps, data, etc.

1. Locate the TV’s settings;
2. Enter “Device preferences”;
3. Choose “Reset”;
4. Confirm on “Factory data reset”;
5. Choose “Erase everything.”

The reset is successful if the TV restarts, and you need to begin setting it up from scratch.

Tip: Save your Roku account details (favorite apps, etc.) so it becomes easier to set everything up again later.

Quick Recap

Don’t be afraid to tweak the audio settings, as those can always be returned to default.
