Hi Craig (@craigah13)
It depends on how you've added your audio.
If you've added it by using code or by dragging it onto the scene then you could mute it using the .muted property. For example:
if (audioElement.muted) {
audioElement.muted = "";
} else {
audioElement.muted = "true";
}
audioElement is a variable that holds the audio instance so
var audioElement = document.createElement('audio');
or
var audioElement = document.getElementById('myAudio');
in your case you would probably need to collect all your audio in an array
var audioElements = document.getElementsByTagName('audio');
for(var i=0; i < audioElements.length; i++) {
if (audioElements[i].muted) {
audioElements[i].muted = "";
} else {
audioElements[i].muted = "true";
}
You could add this Javascript to a button (or any element) using the "On Mouse Click"
