Vizio TV and Sound Bar Out of Sync

As a frustrated Vizio TV and Sound Bar owner, I have been dealing with the issue of my audio being out of sync with the video for some time now. After a lot of research and trying out various tips and tricks, I believe I have finally found the solution to this problem.

In this blog post, I will be sharing with you how I managed to fix the issue, as well as any other solutions I encountered in my research. So if you’re having the same issue as I did, read on and hopefully you’ll find the answer in this post.

Usually, the issue will be with the Bluetooth connection or a hardware problem with the sound bar. Aside from that, corrupt software may lead to audio delays.

Causes of Vizio TV and Sound Bar Sync Issues

In order to fix Vizio TV and sound bar sync problems, you have to understand what’s causing the issue. So, let’s jump into some of the common culprits. 

  1. Connection Issues

Typically, when there’s an audio problem with the Vizio sound bar, the cause is faulty connections.

When you buy a new sound system, the setup is pretty simple. Most of the time, all you have to do is plug in the speakers, then use Bluetooth to link to the TV.

However, this easy setup leaves room for many errors to pop up. For example, because we only use wireless means to connect the TV and sound bar, the link isn’t stable.

Any movement around the devices may cause a slight audio delay.


There are a couple of ways you can deal with this. For starters, try moving the sound bar out of the way.

To do that, you’ll need to disconnect the device and untangle it from its position. Then, find a location for it away from other electronics. That way you avoid any interference moving forward.

Once the sound bar is in a new location, you can link it to the TV.

If this doesn’t take care of the issue, you may need to invest in a few wires. Instead of relying on Bluetooth, try using a cable connection. This may not be an option depending on your speakers.

  1. Sound Bar Malfunction

When you notice audio delays with your TV and sound bar, pay closer attention to the sound profile. 

If you hear a static noise in the background, it’s likely there’s a hardware issue with the speakers.

This can happen due to excessive use or using the device at incredibly high volumes. That leads to vibrations that may shake the internal wires out of place.


The first step to dealing with a sound bar malfunction is to turn off the device. Then, unplug the power source and let your device rest for a while.

After about an hour, push the power button on the sound bar and hold it for around 30 seconds. Do this without plugging in the power cord. This will allow any residual charge inside the device to dissipate.

Next, you can plug in your sound bar and let it sit idle for about 15 minutes. Finally, connect the speakers to your TV and test the audio.

Make sure the TV is running for at least half an hour before you make a judgment. 

If you still experience audio delay, then you may need to ask for professional help. 

Contact the Vizio support page. There, a qualified representative can help you figure out the next steps to fixing the sound bar.

  1. Corrupt Software

Another reason your audio may be acting up is corrupt software. Both your TV and sound bar need the latest firmware version to connect to each other.

That’s why the two devices will continuously download new software online. However, sometimes the update doesn’t install on your gadgets properly.

When that happens, compatibility issues will arise. This will lead to many playback errors, including time delays.


To deal with this issue, you’ll need to install a fresh copy of the latest software. We can do that through the Settings menu.

  1. Unplug both the Vizio TV and the sound bar.
  2. Leave the devices without power for about 20 minutes.
  3. Connect the power plugs back to an outlet.
  4. Use your remote to turn on the TV.
  5. Click on the Menu button on the remote.
  6. Go to the Settings tab.
  7. Navigate to the Update Software option.
  8. Click ok to search for any new updates online.
  9. Download and install any files that show up.
  10. Follow the instructions on the TV screen to complete the process.

Once that’s done, both devices should be up to date.

Wrapping Up

Why are your Vizio TV and sound bar out of sync? The most common culprit is connection issues. There may be a problem with Bluetooth signal interference.

To resolve this, all you have to do is move your sound bar.

Besides that, the speakers may malfunction and cause audio delays. In that case, you can try power dissipation or call a professional. 

Other than that, the TV software may need an update.
