Just put this on the click function:
//resume audio context of any Hype version
for (var key in window) {
if (key.substring(0, 9) == "HYPE_gac_"){
window[key].resume();
}
}
Update: here is an example
unlockAudioOnClickHandler.hype.zip (69,3 KB)
Hint: You only need to unlock once so if you have a splash screen with a button/tap and sound+unlock… then that should do it for the rest of the document.
