Play audio and restart it onclick

To just restart the song, you'd do:

function play() {
    var audio = document.getElementById('audio1');
    if (audio.paused) {
        audio.play();
    }else{
        audio.currentTime = 0
    }
}

FIDDLE

To toggle it, as in the audio stops when clicking again, and when click another time it restarts from the beginning, you'd do something more like :

function play() {
    var audio = document.getElementById('audio1');
    if (audio.paused) {
        audio.play();
    }else{
        audio.pause();
        audio.currentTime = 0
    }
}

FIDDLE

soundManager.setup({
preferFlash: false,
//, url: "swf/"
onready: function () {
    soundManager.createSound({
        url: [
            "http://www.html5rocks.com/en/tutorials/audio/quick/test.mp3", "http://www.html5rocks.com/en/tutorials/audio/quick/test.ogg"
        ],
        id: "music"
    });
    soundManager.createSound({
        url: [
            "http://www.w3schools.com/html/horse.mp3", 
        ],
        id: "horse"
    });
    soundManager.play("music"); 
}

}).beginDelayedInit();

And to start horse and pause all other sounds currently playing in a click event:

$("#horse").click(function () {
soundManager.stopAll();
soundManager.play("horse");

});
