If you’re experiencing the frustrating issue of no sound on your Vizio TV, you’re not alone. While Vizio TVs are known for their affordability and quality, like any technology, they can occasionally run into problems. Among the most common is the dreaded “no sound” issue, where the visuals work perfectly, but the audio is completely silent. This can be particularly annoying when you’re in the middle of your favorite show or movie, so let’s get it fixed!
Quick Checks Before Troubleshooting
Before diving into more complex troubleshooting steps, it’s essential to perform some quick checks to ensure you haven’t overlooked a simple solution. These checks can save you time and frustration by resolving the issue quickly.

2. External Devices and Connections

II. Headphones: Check if headphones are connected to the TV’s audio output jack. If they are, disconnect them to see if the TV’s speakers start working.
3. Input Selection
I Correct Input: Ensure that the TV is set to the correct input for the device you’re using (e.g., HDMI 1 for a Blu-ray player). Sometimes, switching to a different input can resolve the issue if the current input doesn’t support audio.
Step-by-Step Methods to Fix Vizio TV Sound Issues
Basic Fixes
If your Vizio TV has no sound, start with these simple solutions before moving on to advanced troubleshooting. These steps often resolve the issue quickly and require minimal effort.
1. Adjust Volume Settings
- Check the Volume: Ensure the TV is not muted or set to a very low volume. Use the remote control or the physical buttons on the TV to increase the volume.
- Test Remote Functionality: If the remote isn’t responding, check its batteries and buttons to ensure it’s working properly.
2. Power Cycle Your Vizio TV
A temporary glitch in the TV’s system can sometimes cause audio issues. Performing a power cycle can reset the system and restore sound.
- Turn off your TV and unplug it from the wall outlet.
- Wait for at least 60 seconds (this ensures a full reset).
- Plug the TV back in and turn it on.
3. Check Audio Cables and Connections
Loose or damaged cables can disrupt audio output, especially if you’re using external devices like soundbars or speakers.
- Inspect all connected cables (HDMI, optical, etc.) for damage or loose connections.
- Disconnect and reconnect each cable securely.
- If possible, test with new cables to rule out cable-related issues.
4. Verify Audio Output Settings
Incorrect audio output settings can lead to sound issues, especially when using external devices.
- Go to your TV’s menu and navigate to Settings > Audio >Speaker
- Set it to Auto to allow the TV automatically switch between internal speakers and an external soundbar.
5. Test Different Inputs or Feeds
Sometimes, the issue may be with the signal source rather than the TV itself.
- Switch between different inputs (e.g., HDMI 1, HDMI 2) to check if sound works on another input.
- Test with different feeds, such as streaming apps or a connected cable box, to identify if the problem lies with a specific source
Vizio TV No Sound with External Speakers or Soundbars
If you’re using external audio devices like soundbars or speakers, the problem might stem from improper setup or compatibility issues.

- Select Correct Audio Output: Go to Settings > Audio on your TV and choose the right output option (e.g., Optical Out or HDMI ARC).
- Test with New Cables: Faulty cables can cause audio disruptions. Replace them with new ones to rule out damage.
- Power Cycle External Devices: Turn off the soundbar or speakers, unplug them, wait for 60 seconds, and reconnect them.

- Update Streaming Apps: Ensure all apps are updated to their latest versions by visiting your TV’s app store.
- Check Broadcast Signal: If the issue persists on specific channels, contact your cable provider to confirm signal quality.

- Inspect HDMI Ports: Damaged HDMI ports can disrupt audio signals. Try connecting to a different port on your TV.
Persistent Issues After All Fixes
