Turn up the Vizio soundbar volume:

Turning up the volume of the Vizio Soundbar is a No-brainer that most users tend to forget. The first thing that you need to do, if you’re experiencing an audio cut out is to check if you’ve muted the soundbar. 

If the soundbar is muted, definitely, you won’t be able to hear anything. Try to unmute the soundbar and see if the problem is fixed; if the problem still continues to exist you should proceed to the next step.

In most cases, this would solve the issue; however, if the audio is still cutting out, chances are that your audio cable (HDMI or digital optical) is damaged. Try to change the cables to solve this issue. 

If the audio cut out is fixed, you’re good to go; otherwise, continue to the second step. 

Diagnosing the problem: 

What if your Vizio soundbar isn’t the problem?

Try to attach different devices with the Vizio soundbar to see if the voice is still cutting out.

Giving Your Vizio Soundbar a Break:

Just like any electronic device, your Vizio soundbar needs a break too. If you’ve been using it for an extended period, it might get heated, which could be the culprit behind the audio cut out. It’s a good practice to turn off the soundbar and let it cool down for a while. You could do this during a lunch break or overnight, ensuring it gets ample time to cool down. This simple step could solve the temporary audio cut out issue and prolong the life of your soundbar.

A Breath of Fresh Air for Your Soundbar:

Over time, dust and dirt can accumulate inside your soundbar, and believe it or not, this could interfere with its performance leading to issues like audio cut out. A straightforward solution to this is cleaning your soundbar with compressed air.

Here’s how you can do it:

  1. Power Off: Ensure that your Vizio soundbar is turned off and unplugged from any power source to avoid any electrical mishaps.
  2. Get a Can of Compressed Air: Purchase a can of compressed air from a nearby electronics or hardware store. They are relatively inexpensive and are excellent tools for cleaning electronics.
  3. Gentle Sprays: Hold the can of compressed air at a slight angle, and with gentle, short sprays, clean the ports, vents, and any other openings on the soundbar. The aim is to dislodge any dust or debris that might be interfering with the soundbar’s functionality.
  4. No Moisture: Ensure that no moisture enters the soundbar while you are cleaning. Compressed air is usually moisture-free, but it’s always good to be cautious.
  5. Let it Dry: Before you plug the soundbar back in, give it a few minutes to ensure that any dislodged dust has settled or escaped from the soundbar.

Performing this cleaning routine once in a while can keep your Vizio soundbar in pristine condition and ensure a great audio experience every time.
