unity trigger is called in beginning

I have a sound that gets triggered with OnTriggerEnter, and picking up whether sound is playing to turn sprite renderer on/off.

For some reason, when I start the game, the sound starts playing (which should only be getting called by the trigger).

I checked the trigger with the players tag and debug.log to console, and found that the trigger method isn't being called at the start. But, for some reason, the sound is getting played at the start and when I hit the trigger(but not turning the sprite renderer back on).

FlagScript

#pragma strict

var Sprite2 : Sprite; //second sprite to renderer

var sr : SpriteRenderer;

var hasBeenHit : boolean = false;
var flagCollisionSounderies: AudioSource;
var flagCollisionSound : AudioClip = null;
private var applauseRef: ApplauseScript;
private var go: GameObject;

var count : int = 0;


function Start () {
//access the spriteRenderer
flagCollisionSound = flagCollisionSounderies.clip;
sr = GetComponent(SpriteRenderer);
go = GameObject.Find("ClapMaster");
applauseRef = go.GetComponent(typeof(ApplauseScript));
//Debug.Log("bool: "+flagCollisionSounderies.isPlaying); //true already

}



function OnTriggerEnter2D(coll: Collider2D){
//Debug.Log("flagtriggered");
//change the flag to other flag
sr.sprite = Sprite2;
if (coll.gameObject.tag == "Player"){
    Debug.Log("poos");
    if (hasBeenHit == false){
        GameMaster.setFlags(GameMaster.getFlags()-1);
        GameMaster.addPointsToScore(100);

        if (flagCollisionSound != null){
            flagCollisionSounderies.PlayClipAtPoint(flagCollisionSound, transform.position);
            //Debug.Log("bool:" + flagCollisionSounderies.isPlaying);
            applauseRef.animRenderer.enabled = true;

        }
    }
}
hasBeenHit = true;  
}

function Update(){

    if(!flagCollisionSounderies.isPlaying){
        applauseRef.animRenderer.enabled = false;
        //applauseRef.playApplauseAnim = false;
    }else{
        //Debug.Log("sounderies     detecteddFsdlfkjsdlfksjdflksdjflkj1123123");
    applauseRef.animRenderer.enabled = true;
    //applauseRef.playApplauseAnim = true;
}


}

Applause Script

}

    function Update(){
        PicMover();
        frame = (frame +1 ) % 4;
        animRenderer.sprite = animSprites[frame];   

}   



static function PicMover(){

    if(Ymove < 20 && goingUp){
        Ymove++;
    }else if(Ymove > -20 && !goingUp){
        Ymove--;
    }else if(Ymove == 20){
        goingUp = false;
    }else if(Ymove == -20){

    }
    animRenderer.transform.position = new Vector2(10,10);
