How to reset a Vizio sound bar

A Vizio sound bar offers a great way of amplifying audio from an external device without resulting in purchasing a whole speaker system.

For example, most TVs today are slimmer and do not have enough room for a decent internal speaker. You can use a Vizio sound bar to make your TV-watching better.

But sometimes you may encounter a problem with the Vizio sound bar whereby it stops working, is static, or has audio and connection problems.

When you face these issues, the quickest fix would be to reset your Vizio sound bar.

Generally, the steps for resetting a Vizio sound bar will depend on your model. Vizio sound bars come in many models.

Therefore, to factory reset your Vizio sound bar, you need to determine its model number first. You can find your model number on the side of the packaging or box, the back of your device, or in your quick start guide.

However, most reset procedures are almost the same.

If you do not see any lights, ensure you have secured the power cord to the outlet and the sound bar. Confirm that the outlet has power by trying a different device.

2. Verify that you have set the Vizio sound bar to the correct input

Here is how to check that you have set your Vizio sound bar to the correct output:

  • Power on the TV and play an audio or video file.
  • Press and hold the Input button on your sound bar.
  • Continue holding until you see flashing LED lights.
  • An Auto Input Search will begin.

You will see the LED lights flashing again to indicate the device is going through the inputs available to find the one plugged into the TV.

3. Connect the Vizio sound bar to an Audio Out port

Generally, your TV has many ports with different functions. Most of them are inputs that work to introduce audio and video into the TV.

But for this fix, only connect the sound bar to an output. You will find the Audio Out port on the back of your TV labeled as Audio Out.

4. Connect a different device to the sound bar

Most issues with the Vizio sound bar tend to come from the device to which you are connecting.

If there is sound coming out, the Vizio device is working, and you have an issue with your TV. But if you find problems, contact support services for further assistance.


You can reset your Vizio sound bar with or without a remote.

The best way is to press and hold the Bluetooth and Volume Down buttons for five seconds simultaneously and wait for all LEDs on the device to flash three times.

Once done, the settings will go back to factory defaults.
