best way to preload audo and then play ?

ok I have my image.. that is shaking.. working on that in last post.. and I need to make the shaking
start right when audio plays.. or other way around.. just want them both to run at the same time..

so I had this code code to embed.. but it just plays when its ready

HTML Code:

---

<audio preload autoplay>
  <source src="ElectFizzle.mp3" type="audio/mpeg">
  <source src="ElectFizzle.OGG" type="audio/ogg">
  <embed  src="ElectFizzle.mp3">
</audio>

---

and now I'm trying the audio class.. but it doesnt ever play.. I do something wrong or really wrong.. or
should I just try something else ?

Code:

---

function SyncAudioVibrate() {
        iStartPos=document.getElementById("Logo1").offsetLeft;

        StartPos=iStartPos.toString()+"px";

    var audio = new Audio();

       
    audio.addEventListener('canplaythrough', LogoAction(audio), false);
    audio.src = 'ElectFizzle.OGG';
       
        }

function LogoAction(Myaudio) {


        vibrate();

        Myaudio.play();
}

ideas ?
