You might have accidentally changed the audio input on your TV while using the remote control spontaneously. On your Vizio TV remote, there’s a small button (the AUX button) that allows you to change the audio input, once this button is tapped, there will be no sound on the screen till you change it back.

Below are the steps on how to change Audio input settings on your Vizio TV:

  • Locate the “INPUT” button on your TV remote control.
  • Tap it once, and then choose “Soundbar” in case you have a soundbar connected to your TV, or “Default” if you are using the TV speakers.

That’s it! You have successfully changed the audio input settings on Vizio TV. This should fix the Vizio TV sound not working, but if it doesn’t proceed to the next troubleshooting step below. 

Ensure the volume on the Satellite Box is above zero

Are you using a cable or satellite box? If yes, then check if the volume is set higher than zero in the interface settings.

Your cable box offers the video and audio signals that are eventually transmitted via the TV, which may appear odd if you are not familiar with TV settings.

Once your cable box’s volume control has been set to zero, the cable box informs your TV not to play any sound.

Check the Current Sound Source

Do you know the sound problem you are encountering may be coming from the TV itself and not from the channel? If you are getting no sound on channels like ESPN and FX, then you should check your cable settings.

Cable channels are usually known to have problems with the audio, therefore if this issue is not affecting your other devices (such as Blu-ray players or PlayStation), then you should check out your cable box.

You can as well change to a Watch TV source to see if the problem is coming from the device you are using to play content on your TV. In case it’s the device you use to send content to the TV, ensure to restart the source and test again.Vizio TV Sound not Working

Check Vizio TV Volume

Although this sounds too easy, It’s possible you might have accidentally turned off the volume of your Vizio TV. Here are steps to follow that can help you fix this problem and make your TV sound like it should:

  • Turn on the Mute button on your remote control.
  • Change the TV’s volume from the panel right in front of the set.
  • Vizio TV has a very simple-to-follow, press-and-look process to see if your TV is muted or not.
  • Tap the Mute button on your remote control. 
  • Once a highlighted icon is displayed at the bottom left of your screen, then your TV is muted. 
  • In case you tapped the Mute button for the first time today, then you need to look into it further.

If checking the TV volume doesn’t solve the issue of Vizio TV not working, then you can proceed to the next step below.

Check all Cable Connections

The next step that can help you fix the issue of Vizio TV sound not working is to check if all the cables are connected properly and are functional especially when you are still experiencing static sound on your Vizio TV.

Always ensure that the audio cable is firmly plugged into both the TV and the audio output device, such as an HDTV or home theater receiver. In case you are using a third-party device to listen to your Vizio TV sound, double-check to ensure it’s also fully functional.

A loose or unplugged cable may be causing interference which may prevent you from hearing the sound from your TV. 

Check the Remote Batteries

In case none of the fixes listed above has solved your Vizio TV sound not working problem, then you could try replacing or testing your remote batteries.

When your Vizio remote won’t work, it doesn’t automatically imply that your TV is faulty. To be sure what the exact problem is, first check out the battery compartment and ensure that the batteries are properly installed and functional.

In case the remote won’t still work, then it’s possible that your remote has been damaged due to one reason or the other or it just needs to be reset. You might need to discharge all residual power in the remote to get it working again.

  • Detach all batteries from the remote control.
  • Press every button several times.
  • This will help clear the memory and reset the device.
  • Now, re-insert the batteries and try using the remote again.

This should work and if it doesn’t, you can use an Xfinity remote or any of your remotes. All you need to do is pair it to the Vizio TV for them to work. If you have another Vizio remote, check out your remote’s operating manual before proceeding.

Disable SRS TruVolume

You might need to disable the “SRS TruVolume” function so your Vizio TV sound can work again. This SRS TruVolume feature usually conflicts with external devices, such as gaming consoles and set-top boxes like Chromecast, Roku, and Amazon Fire. To achieve this follow the steps below:

  • Go to Settings >> Sound >> Disable the TruVolume button.
  • The Vizio TV’s TruVolume feature will automatically change the volume of your content based on the onscreen action.
  • Go to Audio Settings >> Advanced Audio.
  • Change the setting from “Prefer SRS” to “OFF”.
  • Switch off any settings on your Vizio TV that can change the audio volume.
  • In case you have “TruSurround” or “Surround Sound” enabled, ensure to disable those settings.
  • Another common cause is when the analog output settings are set to “variable” instead of “fixed”.

This should fix the Vizio TV sound not working issue and if it doesn’t, try the next fix.
