A:Answer Hi misbeachbum, Thank you for your inquiry. Google Assistant can change digital channels coming from the Coaxial connection (antenna or local broadcast), but unfortunately, will not work with other inputs on your TV, such as your Cable box, DVD player, etc. To learn more about what Google Assistant can do, please refer to this link: https://www.sony.com/electronics/support/televisions-projectors-lcd-tvs-android-/kd-55x750h/articles/00186878
Hope this helps!
