No matter how good your Vizio TV is, you can run into different issues occasionally, including no sound. This can be extremely annoying as you can only see the visuals on the screen without audio. In some cases, the problem goes away after you turn your TV off and on. But if that doesn’t work, you’ll have to resort to some advanced fixes.

To help you out, we’re going to explain why your Vizio TV’s sound is not working and what you can do to fix it.

Why my Vizio TV has no sound?

Here are some reasons why there’s no sound coming from your Vizio TV.

  • Incorrect volume settings.
  • Incorrect audio output settings.
  • Faulty cables.
  • Outdated firmware.
  • Hardware problem.
  • Temporary bug or glitch.
  • Check your external speaker.

How to fix the Vizio TV no sound issue

If your Vizio TV has no sound even when it’s not muted, you can try these methods to quickly eliminate the issue.



Adjust the volume settings

Before moving on to any advanced solutions, check the volume settings first. This is because you might have accidentally muted your TV. So, access the volume settings using your remote control and ensure the volume is up and not muted. If your Vizio TV remote is not working, you can use the volume button on your TV for this.



Power cycle your Vizio TV

In some cases, no sound may come from your Vizio TV due to a temporary bug or glitch. Thankfully, this can be fixed through a simple power cycle. 

  1. First, turn off your Vizio TV and remove the cables from the device and power outlet.
  2. Wait for around three minutes.
  3. Plug everything back in and turn on the TV. 

This should fix the Vizio TV no sound issue if it was being caused due to a bug or glitch.

Make sure to power cycle your Vizio TV two or three times if it doesn’t work after the first try.



Make sure the correct output device is selected

If you’re using an external soundbar with your TV, you may not hear anything if an incorrect output device is connected. To ensure this isn’t the case, go to your TV’s menu and access the settings. From here, you can select the correct audio output for your Vizio TV. 



Make sure the audio cables are not damaged

Sometimes, the audio cables connecting the TV to external devices can be damaged or not plugged in properly. Make sure to remove the cable and insert it again. Also, if there are any bends or cuts on your cable, try using a new one, as the current cable might be damaged.



Check if your TV speakers are turned off

If you’re not using any external audio device with your TV, the internal speakers may be turned off, which may be causing the Vizio TV no sound issue. For this, go to your TV’s settings, navigate to Audio, and turn the TV speakers on.



Update your Vizio TV

You may face the Vizio TV no sound issue if you’re running the device on outdated software. TVs need the latest firmware update to operate smoothly, and if you haven’t updated it in a while, now would be the right time to do so.

  1. Turn on your Vizio TV and press the V button on the remote.
  2. Go to System and select Check for Updates.
  3. If there’s a new update available, download and install it.

It can take some time for the TV to update, but it should restore the sound on your Vizio TV.

Make sure to not turn off the TV while it’s updating, as this will end up causing more issues.



Factory reset your TV

If nothing works, your only option is to factory reset your Vizio TV. This will take the TV back to its original settings and remove any bugs or glitches that may be causing the sound issue. 

To factory reset your Vizio TV, follow these steps. 

  1. Access the settings of your Vizio TV and go to System.
  2. Next, select Reset & Admin and then choose Reset TV to Factory Defaults.
  3. Wait for the reset process to finish. 

Make sure to keep a note of all the installed apps and your custom settings, as a factory reset will wipe everything and you’ll have to set up the TV again.



Get in touch with Vizio support

Even if a factory reset hasn’t fixed the Vizio TV no sound issue, it means there’s likely a hardware fault. In such a case, you need to contact Vizio support for further assistance. They will arrange for a technician to examine the TV more closely and provide recommendations for either repair or replacement, depending on what the issue is.

How do I check the sound output on my Vizio TV?

How do I change the audio mode on my Vizio TV?

You can change the audio mode on your TV by going to Settings/System > Audio/Sound. From here, you can turn the internal speakers off, enable Surround Sound, and more.


The Vizio TV no sound issue can be extremely annoying, but it can be fixed through a simple power cycle in most cases. If that doesn’t work, try adjusting the output and volume settings, updating the TV, and factory resetting it. But if nothing works, contact Vizio support for further assistance.
