New Policy for Video Autoplay

Video Backgrounds will no longer play an audio for Chrome and Safari

Any Video Embed Autoplay with audio soundtrack doesn't autoplay with the latest versions of Safari and Google Chrome.
Safari and Chrome will block obtrusive video ads, and by extension, the Video autoplay as well. This is a new behavior implemented by these browsers. 

This will also mean that the Video Backgrounds may not play on the following browsers if they are played with sounds.
In order to comply with the New Policy for Videos, we now remove the audios from Video Backgrounds so that it will still be played.
