Revolution Slider Adjustments - I want custom button to sound on - sound off in revolution slider

I have a wordpress website where i use revolution slider on my homepage. The version of the revolution slider is 5.0.4.1 I want to have the ability to mute and unmute with an nice simple button logo/layout. The button must be responsive and work on different platforms. I have currently an video which is repeated constantly which starts muted. So my request is i want to have an button to unmute it or mute it back. If your up to this let me know, Shouldn't be hard for the scripters or plugin customizers. I want this be done in 1 day maximum.
