hi
I want to test my first vr project and create a new vr and only add a sound entity and run it when box selected with

Box.prototype.onSelect = function () {
    // Change the status bar material to the 'selected' texture
    this.loadingBarModel.materialAsset = this.barSelectedMaterial;
    var sound = this.app.root.findByName("Sound");
    sound.sound.play("Slot 1");
    this.boxModel.materialAsset = this.boxHighlightedMaterial;
};

its work on system browser bot error on iphone
