Script for Movie sound ontriggerenter in Unity 5

I have this by joining two pieces of code. It's working!

Can you tell me please how can I have sound on movietexture? I am not a programer.

 #pragma strict
 
 var movTex : MovieTexture;
 var loop : boolean;
 
 function OnTriggerEnter(other : Collider)
 {
     if(other.tag == "Player")
     {
         GetComponent.<Renderer>().material.mainTexture = movTex;
         movTex.Play();
         movTex.loop = true;
     }
 }
 function OnTriggerExit(other : Collider)
 {
     if(other.tag == "Player")
     {
         GetComponent.<Renderer>().material.mainTexture = movTex;
         movTex.Pause();
     }
 }

Thank you in advance!
