  • The sound bar will power off when an update is available. It will download the new firmware and install it automatically.
  • The update process can take up to 30 minutes. Take note that the connection to the SmartCast app to the sound bar will be lost as the update is being installed.
  • Once completed, the power LED will remain on and the SmartCast app connection will be restored.

If your Vizio sound bar is not downloading the update through the SmartCast mobile app, then you can try to manually download and install the device software update.
