A:Answer The Crave does not have the optical or right and left analog ports that are standard on our sound bars. It uses the Vizio Smartcast app to set it up and then either wifi or bluetooth to send over audio. It does have one analog port for other devices. If you are looking for an external speaker for you flat screen tv, I would suggest one of the Vizio sound bars. If you have any questions on the sound bars, or would like information on a sound bar, please feel free to contact our Vizio support at 855-833-3221.
