Header video not sound and not working on mobile

luismario.com Hello, I sent you a message when I purchased the theme and I never heard back from you which it is unusual, and I do not see my question posted here either, I am an old CatchThemes user, I need help ASAP. 1. I am having issues with the video on the header that is not sounding or sounds rarely, I have tried it in several computers and mobiles with no good results. 2. Also the video does not reproduce in mobiles contrary to what the mobile testing icons show. Please show me how to correct these two issues. Thank you.
