Automute

Note that the default settings are for autoplay and automute to be "off" indicated by the white circle on the slider. Shifting those to the "on" position will turn the dot blue. Autoplay when "on" (blue dot) will play the video as soon as it appears on the screen, when white and "off" a play button will appear for the viewer to select. Automute when "On" (blue dot) means that the audio will not play, even if the the video is playing.
