Audio NullReferenceException when trying to get AudioSource

Hi,

I have an AudioSource added to my project and it plays sound properly.
When I try to access the AudioSource to pause/unpause I get a NullReferenceException.

Here is the code I've been using below:

Code (CSharp):

1. private AudioSource audioSource;
2.     void OnApplicationPause (bool isPaused)
3.     {
4.         Debug.Log ("unity-script: OnApplicationPause = " + isPaused);
5.         audioSource = GetComponent<AudioSource>();
6.         if (isPaused == false)
7.         {
8.             audioSource.Pause();
9.         }
10.         else
11.         {
12.             audioSource.UnPause();
13.         }
14.     }

 

" audioSource = GetComponent<AudioSource>(); "

Is this script attached to the same GameObject that's holding the audio source? If not you need to reference it, which would explain the nullreference
