Create a global variable IsMuted and when it's set on any layout, it sets the global variable... and then all your code to play sounds/music whatever includes the condition IsMuted = false (or 0), then play the audio.
Nevermind... you're looking for the actual control, not the effect.
Can't you just create a new copy of the control on the current layout when it's loaded and then copy the settings from the original on or store them globals?
