Audio not coming

Hello Team BG Stock,

Thanks for such a wonderful and easy to use plugin. I am facing two issues with the plugin:
1. When I upload video in the Row Background it’s not showing Video. I checked various settings but no luck.
2. When I add Video through Hero Widget, it works. But, it doesn’t play the Audio.

Here is the Video URL https://bit.ly/2AE0YeR and here is the website url: https://bit.ly/2JxnYza I am using Video background in the Banner Section.

Thanks for your help in advance!
