Hi Patricia, thank you for leaving a review with your feedback. Though you've purchased a sound bar to experience top-of-the-line audio performance, please feel free to reach out to our customer support agents if you'd like any help adjusting your audio settings on your TV. You can reach them at 844-254-8087.

Hello Brooke, this TV uses our SmartCast Platform which offers a host of built in apps, as well as support for Google's Chromecast, Apple's AirPlay 2, and voice support for SIRI, Google Home, and Alexa. You are not able to manually download additional apps, however new apps are added to the platform often. If you find there is an app you want to watch that is not on SmartCast you may be able to cast it using Chromecast or Apple AirPlay from your phone or mobile device. If you’d like any help taking advantage of all the options VIZIO has to enjoy your content, our customer service team would be happy to speak with you at 844-254-8087.
