Sorry not found iPad to test this bug; but i looked the code ;
Application.js
Code
606 // Specific sound handling if on iOS
607 this.iOS = !!(/iPad|iPhone|iPod/.test(navigator.platform)
608 || (navigator.platform === "MacIntel" && typeof navigator.standalone !== "undefined"));
609 if (this.iOS && this.soundBank.nHandlesReel > 0) // && (this.dwOptions & CRunApp.AH2OPT_LOADSOUNDSONTOUCH) != 0)
610 {
611 this.silentSound = new CSound(this);
612 this.silentSound.loadSilent();
613 }
If someone having issue change to following ... maybe it can work or what happen ?;
if (this.iOS)
{
// this.silentSound = new CSound(this);
// this.silentSound.loadSilent();
}
