Disabling Audio Listener in unity 3d

Hello,

I have the cataluna from the car tutorial which i have put into my own game and modified so you can enter and exit the vehicle. A problem I ran into was that now i have multiple cameras and disabling the camera itself does not turn off the audio listener. The code to switch cameras works but i cannot figure out how to disable the listeners. I want the car camera listener when i cam in the car to be one, and the player listener to be on when im out as the player. Ideally i would like to keep in it the same script but im open to creating more scripts to get the job done. Heres the code i have been working with. Right now attached to a trigger object to get in and out of the car.

var car : Transform;

var player : Transform;

var exitPoint : Transform;

var doorTriggerLeft : Transform;

var PlayerCamera : Camera;

var CarCamera : Camera;

var isPlayerVisible : boolean;

function Update(){

 if (Input.GetButtonUp("Enter Vehicle")&& isPlayerVisible){

     // make player invisible and still standing

     player.gameObject.SetActiveRecursively(false);

     player.gameObject.active = false;

     // parent player to Exit Point

     player.parent = exitPoint.transform;

     player.transform.localPosition = Vector3(-1.5,0,0);

     // parent PlayerParent to car

     exitPoint.parent = car.transform;

     exitPoint.transform.localPosition = Vector3(-0.01,1,0);

     // Enable Car as controllabe object

     GameObject.Find("Car").GetComponent("Car").enabled=true;

     ChangeCarCamera();

     }

     else

     {

 if (Input.GetKeyUp("r")){

     // make character visible again

     player.gameObject.SetActiveRecursively(true);

     player.gameObject.active = true;

     // unparent player from everything

     player.transform.parent = null;

     // parent Exit Point to door Trigger

     exitPoint.parent = doorTriggerLeft.transform;

     // disable car as controllable

     GameObject.Find("Car").GetComponent("Car").enabled=false;

     ChangePlayerCamera();

     }   

 }

}

function OnTriggerEnter(Player : Collider) {

 isPlayerVisible = true;

 }

function OnTriggerExit(Player : Collider) {

 isPlayerVisible  = false;

 }

 

function ChangeCarCamera() {

 PlayerCamera.enabled = false;

 CarCamera.enabled = true;

 PlayerCamera.GetComponent("Audio Listener").enabled = false;

 CarCamera.GetComponent("Audio Listener").enabled = true;

}

function ChangePlayerCamera() {

 PlayerCamera.enabled = true;

 CarCamera.enabled = false;

 PlayerCamera.GetComponent("Audio Listener").enabled = true;

 CarCamera.GetComponent("Audio Listener").enabled = false;

}
