Getting a sound trigger to work - audio

Question

I don't understand why my sound trigger is not working. I have created a GameObject and added an Audio Source to it (on Audio Source I have the Play On Wake and Loop checked. Then I added a Sphere Collider (I have the Is Trigger checked). Finally I added my script and added the sound clips into the inspector. Unity also says that: "There are 2 audio listeners in the scene." I have pretty much unchecked all the audio listeners and it still says it, what am I doing wrong?
Here is a look at my code:
#pragma strict
var WalkAudio:AudioClip;
var OutCry:AudioClip;
function Update (){
var Audio= gameObject.GetComponent(AudioSource);
if(Input.GetButton("Horizontal") || Input.GetButton("Vertical"))
{
Audio.Play();
}
else
{
Audio.Pause();
}
}
function OnControllerColliderHit (hit : ControllerColliderHit)
{
var Audio= gameObject.GetComponent(AudioSource);
if (hit.gameObject.tag == "templeFloor")
{
var groundType = 1;
print("Temple");
Audio.clip=OutCry;
}
else{
Audio.clip=WalkAudio;
}
}

As you said:
I have pretty much unchecked all the audio listeners
The component AudioListener attached to the Main Camera must be enabled. Probably you have used LoadLevelAdditive so you have two camera and two AudioListener components, one on each of them. Please make sure this additive camera and any other gameObject should have this component disabled.
Also at runtime, you can search which component(s) have AudioListener component attached using this in the Hierarchy window search bar.
t:AudioListener
This should help you out. Also double check using Debug.Log that OnControllerColliderHit function calls and Audio.clip is not null after assignment. Also is it necessary to play sound in Update ?
Also, you should move this line from Update to Start function instead, due to performance cost:
var Audio= gameObject.GetComponent(AudioSource);
and use this Audio variable throughout your script.
