I have been searching all day. I know that autoplay does not work on mobile and that makes sense. But i want to know why is this not working. Is there a work around for this. The below code works perfectly on desktop but not on mobile.

var audio = new Audio('sound.mp3');
audio.play();

Very old question but I ran into it a few times on my journey to the solution to my problem which was that audio seemed to work perfectly fine on desktop but not at all on select mobile browsers.

My problem was that in a touchevent I was doing e.preventDefault() which (somehow?) made the event 'not trusted' meaning everything looked fine but no audio would play.

I fixed it by just not using the touch event and relying on the click event which is fired after and setting touch-action: manipulation in the css. Not the best solution, but hey. Pretty silly the event bees non-trusted on a tap on a control to play the sound with a prevent default so that it won't zoom in on a double tap.

Hopefully this helps someone with a similar problem.

(from ment from Manuel Graf on this question)

As others have alluded, a mon problem with JS html5 audio on mobile is the scope that instantiates the Audio object needs to be in response to a user action.

Maybe this is in a onReady function handler, you can handle some kind of click or touch action that initializes the Audio object.

var audio;
$("#startAudio").on("click", function(e){
    if(!audio){
        audio = new Audio('sound.mp3');;
    }
});

This will download the audio file, but should not play it automatically. Once initialized, your code can play the audio audio.play(); as needed
