Start by checking whether the Vizio TV’s source has any sound.

In some cases, however, your TV may be muted or temporarily inaudible if the sound of the broadcast has been muted or disabled for unknown reasons.

Here, we recommend you switch channels to see if the sound issue is caused by your TV or the channel.

You can only wait or change the channel if it is the channel you’re watching.

You can also try switching to a Watch TV source to see if the source device (if any) is the problem.

Restart the source of content you are using for your TV screen and try it again if it is one of them.

Fix 3: Check Vizio TV Volume

Possibly, you’ve muted or turned down the volume on your TV completely.

We are including this method here since many users mentioned that this sometimes happens unintentionally. Please check before moving further.

To find out if your Vizio TV has been muted, press the mute button once.

On your Vizio TV screen, a highlighted icon means that your TV has been muted. In case you’re just now muting your TV by pressing the button, then you should look for the problem elsewhere.

Fix 4: Check Vizio TV Audio Input Settings

You or someone else may accidentally change the audio input while using the TV, while you are unaware of it. A good example is if you press the AUX button on your Vizio smart TV remote, the audio input will be set to AUX mode.

Due to the lack of a connected device of this type, your TV will cease producing sounds until further notice.

Fix 5: Check Cable Configurations

You will need to look at the cable configurations in order to fix the static sound TV volume not working on Vizio TV.

The sound line of your TV may be disrupted by an unplugged or loose cable.

This method requires you to ensure all the cables connected to your TV, including those connected to third-party devices, are functional. Otherwise, they can interfere with your TV’s sound, making it impossible to hear it.

Moreover, you can make sure your TV is plugged directly into a working outlet and that the cables aren’t twisted or under pressure.

It is well known that power dividers cause problems not just with sound but with other aspects as well.

Fix 6: Update Your Firmware

It is possible for software issues to cause problems with the sound on your Vizio TV. It’s always a good idea to make sure the software on your TV is the latest version.

In most cases, Vizio TV will check for and install software updates automatically if it is connected to the internet. Sometimes, this process gets interrupted and your TV runs outdated software.

To update the firmware on your TV, follow the steps listed below.

Step 1: Press the ‘Menu’ button on the remote.

Step 2: Go to System > Check for Updates.

Step 3: To begin the update, select ‘Confirm’ if there is an update available

Step 4: Wait for the update to finish.

Fix 7: Reset the TV to Factory Settings

If your sound not working, you may need to reset the TV to its factory settings. The latest firmware on your TV can also be updated if it contains any known firmware bugs.

You probably guessed it, it’s time to restore your TV to its default settings. The hardware or software is faulty if nothing has helped.

We will do a factory reset in this step to rule out the OS as a cause.

Please Note: A factory reset will wipe clean your TV’s memory, which means all your settings, including WiFi passwords and settings, will be erased.

To Factory reset your TV, follow the steps listed below.

After you are ready, click Watch TV and check if there is any sound. You can still fix your TV if the issue persists and you do not feel like taking it to a repair shop just yet.  

Fix 8: Bypass TV Speakers

The only thing we’ve done thus far is troubleshot the TV speakers. The issue may be originating from their hardware components if they still do not work. In other words, they may need to be repaired.

The Vizio TV can be used if the audio is output via a separate device and not the TV’s speakers.

It does not matter if the speakers no longer work; you can still output audio using another device.

Almost anything can be connected to the system, including 3rd party speakers, HDMI soundbars, or AUX devices. Once you click on the corresponding TV input, the sound should be heard right away.

It should be noted that anything connected to your TV that outputs sound can help determine if your speakers are faulty or not.

The first step to fixing the sound on a Vizio TV is to choose the correct input and power cycle the device. Check your TV volume, your cable box, and any third-party devices. As a final step, try performing a factory reset and bypassing the TV speakers if that does not work.


If you are experiencing this problem, it is important to check the connections on your Vizio TV. Make sure all cables are securely connected to the right ports. If you haven’t changed any cables or settings recently, try turning off your TV and turning it back on again. If there is still no sound, contact Vizio support for further assistance with this issue.
