How to fix the issue?

Here are a few fixes that might help you resolve the issue coming in the Vizio sound bar:

Check the power cord and connections

It is possible that the sound bar is not getting power because the power cord is damaged or not connected properly or the sound bar is not connected to the device properly. Check the power cord and other wires that are connected to the Vizio sound bar and the device for any damage or loose connection and replace the wires if necessary.

Make sure the sound bar is connected to the Audio Out port

There are many different types of ports available on TV and all of them are made for different purposes. Most of the ports on a TV are generally inputs which means they bring audio and video in the TV, but for the soundbar, we need an output port which will send audio out of the TV. The port will be labelled as Audio Out, so make sure you have connected the sound bar to the correct port.

Set the sound bar to the correct input

When you have connected the sound bar to a TV, then the TV allows you to switch between built-in TV speakers and the sound bar you have connected to the TV. It might be possible that you have not selected the Soundbar as your input, so make sure you have selected the correct input. To set input follow the steps below:

  • Turn on the TV, and play a movie or anything on it.
  • Press and hold the Input button on the sound bar until the lights on the soundbar start flashing.
  • It will start an Auto input search and the flash indicates that it is cycling through all the input devices that are plugged into your TV.
