Do you have sample code? Not much to go off of otherwise.

I found the error happened below
(e._node = new Audio, e._errorFn = e._errorListener.bind(e), e._node.addEventListener("error", e._errorFn, !1), e._loadFn = e._loadListener.bind(e), e._node.addEventListener(n._canPlayEvent, e._loadFn, !1), e._node.src = o._src, e._node.preload = "auto", e._node.volume = t * n.volume(), e._node.load()), e;

I made something
`**(function () {
if ( typeof window.CustomEvent === "function" ) return false;
function CustomEvent ( event, params ) {

params = params || { bubbles: false, cancelable: false, detail: undefined };
var evt = document.createEvent( 'CustomEvent' );
evt.initCustomEvent( event, params.bubbles, params.cancelable, params.detail );
return evt;

}

CustomEvent.prototype = window.Event.prototype;

window.CustomEvent = CustomEvent;
window.Event = CustomEvent;

})();**`

this is what i made change only for IE 11 to support customevent and event

return o._webAudio?(e._node=void 0===n.ctx.createGain?n.ctx.createGainNode():n.ctx.createGain(),e._node.gain.setValueAtTime(t,n.ctx.currentTime),e._node.paused=!0,e._node.connect(n.masterGain)):(e._node=new Audio,e._errorFn=e._errorListener.bind(e),e._node.addEventListener("error",e._errorFn,!1),e._loadFn=e._loadListener.bind(e),e._node.addEventListener(n._canPlayEvent,e._loadFn,!1),e._node.src=o._src,e._node.preload="auto",e._node.volume=t*n.volume(),e._node.load()),e

I found the error, if I remove ## e._node.volume=t*n.volume(), from the above code I placed, it is working.

[tywang2006]

It looks like e._node.volume cause the error, when I log t*n.volume(). it is showing 10. is it 10 out of the range of e._node.volume?

[tywang2006]

this._sounds[id].sound = new Howl({ onload: sounds[id]["type"] === "music"?this.onAudioloaded.bind(this):null, autoplay: false, preload: true, volume: sounds[id]["volume"]*10, loop: sounds[id]["loop"], src: [sounds[id]["url"]] });

when you define volume more than 1 in IE 11 that is not webaudio. it will get error. I think for the code e._node.volume=tn.volume(), it should detect if tn.volume() is more than 1, otherwise it will be broken and get the SCRIPT5022: IndexSizeError

Hi,

For me, this happened because I had created a Howl with a volume value of 1.5, like this:

var sound = new Howl({ src: ['sound.mp3'], volume: 1.5 });

It seems that any value above 1 will cause this error in IE 11.

Hope this helps.
