Ajuda Autoplay

Boa noite galera, estou com uma dúvida neste código, queria saber como faço para inserir um autoplay pra executar a música assim que o usuario entrar no site, pois atualmente ele tem que clicar no play pra tocar.

Se alguém puder dar uma força ficarei muito grato.

$(document).ready(function(){

 var status = "stop";
	var dragging = false;

	// init

	var player = $("#zen .player");

	player.jPlayer({
 ready: function () {
 $(this).jPlayer("setMedia", {
 m4a: "audio/song.m4a",
 mp3: "audio/song.mp3",
 oga: "audio/song.ogg"
 });
 },
 swfPath: "",
 supplied: "m4a, mp3, oga"
 });

	// preload, update, end

	player.bind($.jPlayer.event.progress, function(event) {

 var audio = $('#zen audio').get(0);
 var pc = 0;

 if ((audio.buffered != undefined) && (audio.buffered.length != 0)) {
 pc = parseInt(((audio.buffered.end(0) / audio.duration) * 100), 10);
 displayBuffered(pc);
 //console.log(pc);
 if(pc >= 99) {
 //console.log("loaded");
 $('#zen .buffer').addClass("loaded");
 }
 }

	});

	//player.bind($.jPlayer.event.loadeddata, function(event) {
 //$('#zen .buffer').addClass("loaded");
	//});

	player.bind($.jPlayer.event.timeupdate, function(event) {
 var pc = event.jPlayer.status.currentPercentAbsolute;
 if (!dragging) {
 displayProgress(pc);
 }
	});

	player.bind($.jPlayer.event.ended, function(event) {
 $('#zen .circle').removeClass( "rotate" );
 $("#zen").removeClass( "play" );
 $('#zen .progress').css({rotate: '0deg'});
 status = "stop";
	});

	// play/pause

	$("#zen .button").bind('mousedown', function() {
 // not sure if this can be done in a simpler way.
 // when you click on the edge of the play button, but button scales down and doesn't drigger the click,
 // so mouseleave is added to still catch it.
 $(this).bind('mouseleave', function() {
 $(this).unbind('mouseleave');
 onClick();
 });
	});

	$("#zen .button").bind('mouseup', function() {
 $(this).unbind('mouseleave');
 onClick();
	});

	function onClick() {

 if(status != "play") {
 status = "play";
 $("#zen").addClass( "play" );
 player.jPlayer("play");
 } else {
 $('#zen .circle').removeClass( "rotate" );
 $("#zen").removeClass( "play" );
 status = "pause";
 player.jPlayer("pause");
 }
	};

	// draggin

	var clickControl = $('#zen .drag');

	clickControl.grab({
 onstart: function(){
 dragging = true;
 $('#zen .button').css( "pointer-events", "none" );

 }, onmove: function(event){
 var pc = getArcPc(event.position.x, event.position.y);
 player.jPlayer("playHead", pc).jPlayer("play");
 displayProgress(pc);

 }, onfinish: function(event){
 dragging = false;
 var pc = getArcPc(event.position.x, event.position.y);
 player.jPlayer("playHead", pc).jPlayer("play");
 $('#zen .button').css( "pointer-events", "auto" );
 }
	});

	// functions

	function displayProgress(pc) {
 var degs = pc * 3.6+"deg";
 $('#zen .progress').css({rotate: degs});
	}
	function displayBuffered(pc) {
 var degs = pc * 3.6+"deg";
 $('#zen .buffer').css({rotate: degs});
	}

	function getArcPc(pageX, pageY) {
 var	self	= clickControl,
 offset	= self.offset(),
 x	= pageX - offset.left - self.width()/2,
 y	= pageY - offset.top - self.height()/2,
 a	= Math.atan2(y,x);

 if (a > -1*Math.PI && a < -0.5*Math.PI) {
 a = 2*Math.PI+a;
 }

 // a is now value between -0.5PI and 1.5PI
 // ready to be normalized and applied
 var pc = (a + Math.PI/2) / 2*Math.PI * 10;

 return pc;
	}

});

Esse player é o mesmo desse exemplo: http://simurai.com/ZEN-Player/ | https://github.com/simurai/ZEN-Player
