12 Vizio Sound Bar Not Working Troubleshooting Tips

#1. HDMI Arc Not Working

The HDMI Audio Return Channel (ARC) is a feature that allows for audio signals to be transmitted from the TV to the soundbar through an HDMI cable.

When this feature doesn’t work, there could be several reasons behind it.

Firstly, ensure that your TV supports HDMI ARC and that you have enabled this feature in both your TV and Vizio soundbar settings.

If you’ve done this but still face issues, try unplugging all cables connected to your devices and reconnecting them again after a few minutes.

#2. Bluetooth Pairing Unsuccessful


The first step in troubleshooting this issue is to ensure that your sound bar is properly connected to power and turned on.

If it’s still not working, try resetting the soundbar by holding down the power button for 20 seconds.

Once it turns on again, attempt to pair it with your Bluetooth device. If pairing was unsuccessful before resetting, repeat the process after resetting.

Another possible solution is ensuring that both devices are within close range of each other.

Additionally, double-check that the Bluetooth settings on your phone or computer aren’t set up incorrectly; sometimes just toggling these settings off and back on again can fix connectivity problems between devices.

#3. Surround Sound Not Working

This problem may arise due to a variety of reasons, including incorrect settings, damaged cables or connectors, or outdated software.

If you’re experiencing this issue, the first step is to check your soundbar’s audio settings.

Ensure that it is configured for surround sound and that all speakers are enabled in the setup menu.

If everything seems fine on this front, try disconnecting and reconnecting all cables running between your TV and soundbar.

Sometimes loose connections can cause audio problems with Vizio soundbars.

#4. Soundbar Not Working With Apps and TVs

One common issue is that the soundbar may not be compatible with certain TVs or apps.

The good news is that there are a few simple steps you can take to troubleshoot the problem.

Firstly, make sure that your TV and app are both updated to the latest software versions. This will help ensure compatibility between all devices and apps.

Additionally, check whether there are any firmware updates available for your Vizio soundbar as these updates often include bug fixes that address compatibility issues.
