Html5 audio Jquery not working

Hi guys i tried to do player with playlist but have troubles with Chrome. This code doesn't work in Chrome. I can't understand why, because all another brouser work fine.

<audio id="PlayaBle" src="music/Kalimba.mp3" controls="controls" autoplay="Y">
    Your browser does not support HTML5
</audio>

<button id="Next">Next sound</button>

<script>
    $(document).ready(function(){
        var audio=$('#PlayaBle');

        $('#Next').click(function(){
            audio.attr('src','music/Sleep Away.mp3')
            audio[0].pause();
            audio[0].load();
            audio[0].play();
        });

    });
</script>
