• Select Audio Output Mode: Check if the audio is set to “Auto,” “Stereo,” or “Dolby Digital.” Experiment with these settings.

If your TV is connected to a soundbar or home theater system, ensure that the correct output mode is selected. Sometimes, a simple switch from “Surround” to “Stereo” can resolve the issue.

Check HDMI and Internet Connections

Your Onn Roku TV might rely on HDMI or network connections to deliver the best audio experience. Loose cables or a poor internet connection can cause intermittent sound issues.

Check Your Connections:

• HDMI Cable: Ensure that your HDMI cable is securely connected. Sometimes, even a slightly loose cable can cause problems.
• Internet Connection: A stable internet connection is crucial, especially if you’re streaming content. Check your Wi-Fi or Ethernet cable for any issues.
• Input Source: Make sure your TV is set to the correct HDMI input if you’re using an external device.

A quick inspection of your cables and connections can often save you a lot of time and hassle. If you notice any damage to the cables, consider replacing them to avoid future issues.

Factory Reset Your Onn Roku TV

If all else fails and your sound issues persist, a factory reset might be your last resort. This step will erase all your settings and return your TV to its original state, so be sure to back up any important settings or accounts.

How to Perform a Factory Reset:

1. Access the Settings Menu: Navigate to the system or advanced settings section.
2. Select Factory Reset: Look for the factory reset option.
3. Confirm the Reset: Follow the on-screen instructions to complete the process.
4. Set Up Your TV Again: After the reset, you’ll need to set up your TV from scratch.

Warning: A factory reset should be done only after trying all other troubleshooting steps. It’s the digital equivalent of starting over with a fresh notebook—it wipes everything clean.

Use Internal Speakers Instead

Sometimes the problem may not lie with the TV itself but with the external audio setup. If you’re using a soundbar or an external speaker system, try switching back to the TV’s internal speakers to determine if that’s where the problem lies.

Switching to Internal Speakers:

1. Go to Audio Settings: Navigate to the audio output settings.
2. Select Internal Speakers: Change the output from external devices to the TV’s built-in speakers.
3. Test the Sound: Play a video or music to see if the sound returns.

Using internal speakers is a quick way to isolate the issue. If the internal speakers work fine, the problem might be with your external system or its connection.
