Proč když dám dvakrát za sebou s jiným mp3 souborem tak hrají to samé?


<img id="imBut2" src="2.png" onclick="play()" onMouseDown = "document.images['imBut2'].src = '2s.png'" onMouseUp = "document.images['imBut2'].src = '2.png'">
<script>
var audio = new Audio('sklo.mp3');
function play() {
audio.pause();
audio.currentTime = 0;
audio.play();
}
</script>
<img id="imBut2" src="2.png" onclick="play()" onMouseDown = "document.images['imBut2'].src = '2s.png'" onMouseUp = "document.images['imBut2'].src = '2.png'">

var audio = new Audio('hudba.mp3');
function play() {
audio.pause();
audio.currentTime = 0;
