3. Using Vizio App for Audio Troubleshooting

The Vizio app is a valuable tool that can help you diagnose and resolve audio problems with your Vizio TV. By accessing the advanced audio settings through the app, you can troubleshoot sound distortion and other issues effectively.

One of the key advantages of using the Vizio app is that it provides access to advanced audio settings. These settings go beyond basic volume control and allow you to fine-tune specific aspects of your TV’s audio output. By adjusting these settings, you can potentially eliminate sound distortion and enhance overall audio quality.

Adjust Equalizer Settings

Within the Vizio app, you’ll find an equalizer feature that enables you to adjust different frequency bands manually. This allows you to customize the sound profile according to your preferences or troubleshoot any specific distortions caused by imbalances in certain frequencies. Experimenting with these equalizer settings may help alleviate sound distortion issues.

Apply Specific Audio Presets

Another useful feature offered by the Vizio app is the ability to apply specific audio presets. These presets are designed to optimize sound quality for different scenarios such as movies, music, sports, or gaming. By selecting an appropriate preset, you can ensure that your TV’s audio output is tailored for optimal performance in a particular context.
