My audio doesn't play, I'm through my options...

I'm building a simple breakout game and I want to play a sound everytime you hit a block. I've tried everything but it keeps saying that it can't play disabled sounds. Here is a piece of my code from the bricks (note: I'm just a beginner so I may have overlooked things)

 using UnityEngine;
 using System.Collections;
 public class Bricks : MonoBehaviour {
     
     public GameObject brickParticle;
 
     void Awake ()
     {
     }
 
     void OnCollisionEnter (Collision other)
     {
         Instantiate(brickParticle, transform.position, Quaternion.identity);
         GM.instance.DestroyBrick();
         Destroy(gameObject);
     }
 
 }

And here is the code for the sound I want to play

 using UnityEngine;
 using System.Collections;
 [RequireComponent(typeof(AudioSource))]
 public class BrickDestroy : MonoBehaviour {
 
     public AudioClip brickBreak;
     private AudioSource source;
 
     // Use this for initialization
     void Awake () 
     {
         source = GetComponent<AudioSource>();
     }
     
     void OnCollisionEnter(Collision coll)
     {
 
         source.PlayOneShot(brickBreak, 1F);
         Debug.Log ("Sound Played");
     }
 }
 

I've searched most forums without success, I really hope someone can help me here. If you need more information, feel free to ask. Thanks in advance.

EDIT: Does anyone know how to set a delay between the destruction of the bricks and the audio? I figured out when I play the game in the editor and change a timescale in the GM script, the bricks won't break down but sound does play.
