Vizio Soundbar Firmware Update: FAQs

  • How do I know if my Vizio Soundbar is Updateable?

If you have any of the Vizio Elevate, Vizio M-Series, Vizio V-Series, Vizio SB-Series, or Vizio Crave Series, that were released after 2016, your device should allow for updates. While that’s the case, you can also check if your device’s firmware is updateable by installing Vizio SmartCast on your smartphone and connecting with it.

  • Can I Update my Vizio Soundbar Firmware with a PC?

No, you can’t update your Vizio soundbar’s firmware with a PC. This is because Vizio Smart Cast isn’t available for PC. While you can connect your soundbar to your PC via Bluetooth (if your model supports it) you can’t access other advanced settings that’ll allow you to install a firmware update.

  • Why Should I Update my Vizio Soundbar?

Updating your soundbar’s firmware can improve the overall sound quality, fix bugs, and add new features. It can also improve compatibility with other devices, such as your TV and streaming devices.

  • What Should I do if Something goes Wrong during a Firmware Update?

If something goes wrong during the firmware update, your soundbar may not work properly. If this happens, try the following:

  • Restart your soundbar: Unplug your soundbar from the power outlet and wait 30 seconds before plugging it back in.
  • Perform a factory reset: Press and hold the Volume + and Volume – buttons on your soundbar for 10 seconds to perform a factory reset.
  • Contact Vizio support: If you are still having problems, contact Vizio support for help.
