Why Does My Vizio Sound Bar Keep Cutting Out?

It’s no surprise when your Vizio sound bar malfunctions on some occasions despite being a very reliable and durable speaker for your TV and other appliances. Of course, the reasons for these malfunctions differ, but here are a few common causes why the audio on your Vizio sound bar is cutting off.

Audio Input Problems

Most times, the cause for audio input problems could be an incorrectly plugged cable attached to your sound bar. Therefore, it is advisable to disconnect and reconnect all the cables of your sound bar as a first attempt at solving the problem. 

Alternatively, the default audio mode may have been wrongly set, hence cutting off audio for your sound bar.

Outdated/Old Sound Bar

You may be using an outdated version of the Vizio sound bar, which is probably why it is having difficulty maintaining your TV or stereo connection. In this case, you may need to get a newer version of the sound bar and rest the old one.

Sound Bar Needs a Reset

Like every other electronic device, the Vizio sound bar can malfunction because of software bugs or an overload of data. However, regular maintenance is needed for electronic devices, and sometimes, a simple reset of the sound bar may be all it needs.

5 Fixes for Vizio Sound Bar Sound Issues

It’s not a fun experience having your sound bar cut off audio at intervals, and it’s more frustrating when you don’t even have a clue what the source of the issue could be. But, not to worry, with these simple troubleshooting fixes, your Vizio sound bar should be back up in no time.

Check the Input Connections

More often than not, when users complain about the Vizio sound bar losing audio, the issue is almost always traceable to the input connections. In many cases, the cables are wrongly placed and would need to be reseated, or the wireless connections are wrong.

If your Vizio sound bar is connected to a device like the TV or game console, try these fixes:

  • Check that the HDMI cable is well connected, especially if it also affects the visuals. 
  • Confirm that the aux cable and other cables are properly connected and functioning well. 
  • Ensure any of the cables are not damaged. To do this, try testing the Vizio with new cables. 
  • If you are using a Bluetooth connection, ensure that your device is not too far away from the sound bar, as this could cause connection breaks. Your connected device should be at least within 10 meters of your Vizio sound bar.

If all these seem to be working correctly and your Vizio sound bar is still cutting, try connecting with another appliance to be certain the sound bar itself is not the problem. 

Switch Audio Inputs

If the Vizio sound bar still fails to work correctly, try changing to other audio input options like your game console, mobile phone, or other devices to see if it still acts the same way. If the sound bar works properly when connected to another device, then your TV may be malfunctioning and will probably need an update, power cycling, or another troubleshooting fix.

Reset Your Vizio Sound Bar

One other way to fix the audio cutting out on your Vizio sound bar is to reset it. 

Before carrying out a hard reset of your Vizio, turn it off for about 10 seconds and then back on to see if that fixes it. If that fails to work, try carrying out a hard reset of the sound bar. The main aim of a reset is to restore the default settings of your sound bar.

The procedure for carrying out a hard reset depends mostly on the Vizio sound bar model you’re using. However, the standard method can be done  by pressing and holding down the Input and Volume Up/Down button for about 5 seconds. 

Find out which way works for your model by checking the model number on the Vizio website and following the procedure. That usually rectifies the issue.

Update Your Vizio Sound Bar Firmware

The reason your Vizio is cutting off audio could be because of a software bug. If you’ve tried other fixes to no avail, check if there are new updates from Vizio, as it could be the solution to the issue. 

Check for updates by visiting the Vizio support page and searching for your model number and possible updates. If there are updates, click on the most current one to update your sound bar.

Contact Vizio Support

If all these fixes still do not resolve the issue, contact Vizio customer support for technical assistance. If there is still a warranty on your device, the manufacturer will either replace or repair it for you, depending on the warranty status.


When your Vizio sound bar experiences an outage or intermittent cut-outs of audio, you now know what to do to fix it.
