Audio Problem

I am trying to play a audio when an object is destroyed the only problem with that is when I click "Play on Active" It just keeps playing every time the object is spawned. One way I was able to fix this was through turning off "Is Trigger". But when I do that the object just floats away. I do have tumble on it. I do not know if the code or something for it is messed up but here are all the scripts I have attached to it.

Random Rotator

 using UnityEngine;
 using System.Collections;
 
 public class RandomRotator : MonoBehaviour 
 {
     public float tumble;
 
     void Start ()
     {
         rigidbody.angularVelocity = Random.insideUnitSphere * tumble;
     }
 }

Destroy By Contact

 using UnityEngine;
 using System.Collections;
 
 public class DestroyByContact : MonoBehaviour 
 {
     public GameObject explosion;
     public GameObject playerExplosion;
 
     void OnTriggerEnter(Collider other) {
         if (other.tag == "Boundary") {
             return;
         }
         Destroy (other.gameObject);
         Destroy (gameObject);
         Instantiate (explosion, transform.position, transform.rotation);
             if (other.tag == "Player") {
                 Instantiate (playerExplosion, other.transform.position, other.transform.rotation);
             }
     }
 }

Mover

 using UnityEngine;
 using System.Collections;
 
 public class Mover : MonoBehaviour
 {
     public float speed;
     
     void Start ()
     {
         rigidbody.velocity = transform.forward * speed;
     }
 }
