The YouTube app on Fire TV and Android TV devices has started rolling out an, in my opinion, annoying feature where it autoplays videos, with sound, as you browse around. By default, if you highlight a video on the home or subscription feed, the video begins to play within the thumbnail at full volume. Selecting the video at that point will make it full screen at the point where the autoplaying preview has reached. This appears to be slowly rolling out, since the new behavior is not yet available on all devices. Thankfully, it’s easy to disable the feature and return to the previous behavior of silent looping previews. Just go into the YouTube app’s Settings tab, found at the bottom of the sidebar, and turn off the “Previews with sound” option.
