Having trouble playing sound on another gameobject

I am having a heck of a time trying to figure out how to play an audio file that is attached to a monster(with an audio source attached)in my game. I am able to send the damage at him but I can't seem to be able to find the right command to send audio. Attached is the script I am working with.

Thanks very much!

 var hit : RaycastHit;
 var ammoCount : int = 9;
 var bloodPrefab : GameObject;
 var muzzlePoint : Transform;
 var Damage = 2;
 
 function Start()
 {
 }
 
 function Update () {
     if(Input.GetButtonDown("Fire1")){
        ammoCount -=1;
 // Not done here yet but shouldn't matter at all       
        audio.Play();
     StartCoroutine("Shoot");}
 }
 
 function Shoot() {
     var fwd = muzzlePoint.TransformDirection (Vector3.forward);
     if (Physics.Raycast (muzzlePoint.position, fwd, hit, 1000)){
        if(hit.collider.gameObject.tag == "Monster")
        {Instantiate(bloodPrefab, hit.point, hit.transform.rotation);
         hit.collider.gameObject.SendMessage("applyDamage", Damage);
 //All of this stuff works...
         
 //This is the line I'm trying to figure, just need the right syntax.
 //hit.collider.gameObject.SendMessage(audio.Play());
 //hit.collider.gameObject.audio.Play();
 //something.something.something.argh!
 
        }
 
 }
 
 }
 
 function OnGUI (){ 
     GUI.Label (Rect (50, 10, 100, 20),"bullets left: " + ammoCount);
 }
