Answer 1

I managed to do it like this:

 $('#play_audio').click(function () {                     
            var times = 4;
            var loop = setInterval(repeat, 500);

        function repeat() {
            times--;
            if (times === 0) {
                clearInterval(loop);
            }

            var audio = document.createElement("audio");
            audio.src = "files/windows%20default.mp3";

            audio.play();
        }

        repeat();           
    });      
});
