force autoplay on audio player

Question

with the new Chrome update function autoplay audio does not work, would like to know how to force autoplay, already tried so:

document.getElementById("controles").setAttribute('autoplay', true);

Thus:

$("#controles")[0].autoplay = true; 

And so:

var controles = document.getElementById("controles");

function enableAutoplay() { 
    controles.autoplay = true;
    controles.load();
}

And no way it worked, anyone knows why?
