Vizio TV Sound Not Working? Try These Easy Solutions

Having a smart TV, such as a Vizio TV, enhances the movie experience, including the amazing audio. However, if it doesn’t function, being able to appreciate the picture simply might be quite annoying. 

The fact that the sound on your Vizio TV isn’t working doesn’t imply it’s broken. There are still solutions you can do on your own to get the audio from your Vizio TV working again.

Solutions To Fix Vizio TV No Sound Issue

1. Examine the Cables Examine The Cables

Disconnect all wires attached to the TV, as described in the previous method. It might be coming from a set-top box, a DVD player, or a soundbar. 

Check for any loose connections. The HDMI cable can be replaced.

Lastly, Reconnect everything and check to see whether the issue has been resolved.

2. Check All the Connected Devices

Check the connections to see if the TV is linked to a set-top box, Chromecast, or DVD player. To test if the audio isn’t functioning on all of them, Disconnect them or reconnect them one at a time.

It’s possible that the set-top box isn’t synchronizing audio and visuals. Use a streaming device like a Fire TV or Chromecast to play the audio via WiFi. 

Lastly, check to see whether the audio works with the new input.

3. Check the Vizio TV’s Audio Settings

Check The TV's Audio Settings

For this, Check the volume; it’s possible that it’s muted, and you’re unaware of it. Also, check if everything is back to normal by resetting all audio settings to default.

4. External Audio Should Be Checked

Sometimes, the external devices might be faulty. For this, turn off all the external devices and listen to the sound on the TV.

If the sound is good from the TV speakers, your external audio devices are the source of the issue. 

If you’ve recently connected external speakers, double-check that everything is in working order.

5. Remove Your Vizio Television Power Cord

When you unhook the Vizio TV from the wall, the TV sound usually starts to operate. As discussed in this video, the trick works in most cases. 

Unplug the cord for at least 120 seconds. This will allow your Vizio TV enough time to process the disconnection and reestablish its electrical connection.

When your Vizio TV has no sound, this step, which may appear to be simple, is actually quite important. After that, the Vizio TV will quietly reset itself.

The important thing to note here is that this procedure is not the same as just turning on or off the remote control.

After 60 seconds after unplugging, plug it back in to hear the sound from your computer.

6. Update the Software to Latest Version

Here is the way to update your Vizio TV’s software to the latest version.

  1. Press the ‘V’ key on the remote control
  2. Then, Press the Menu button and select System in the Menu.
  3. Then, I select ‘Check for updates from the drop-down menu.
  4. If any updates are pending or available, your Vizio TV will check for them.
  5. If you can find one, click Update.
  6. Select Install from the drop-down menu.
  7. Your Vizio TV will now complete the download of the Update and restart.
  8. After that, it will restart and install the update.

This should have addressed the problem after the second restart of your Vizio TV. Let’s factory reset your Vizio TV system immediately if it hasn’t already been done.

7. Reset Your Vizio TV To Factory Setting

If the sound problem persists after you’ve connected the TV back in, you’ll need to reset the factory settings on your television.

For this, follow these steps:

  • Turn on the television and choose ‘Menu’
  • Select ‘System’ from the ‘Menu’ menu.
  • Choose “Reset and Admin” from the drop-down menu.
  • Now, Select “Reset TV to Factory Defaults” as your option.
  • This setting may ask for a code before attempting to reset the television. The default code for Vizio televisions is 0000 if requested ( four zeroes).

This technique will return your Vizio TV to its factory settings when you first bought it home. In the vast majority of situations, this step resolves the issue of the Vizio TV volume not working.
