How to loop through a list of sounds if(bool)

Question

UPDATE: I fixed the error. audioSource = GetComponent<AudioSource>() is called in Start() but I Start() is never executed I guess. The following works:

  public void PlaySound()
      {
          audioSource = GetComponent<AudioSource>()
          PlayList();
      }

QUESTION: I have the script below attached to gameobject with a audiosource. When a condition is true, I call the function PlaySound() through another script (and when false I call StopSound()). But this isn't working. I get the error:

 NullReferenceException: Object reference not set to an instance of an object
 PlayEatingSounds.PlayList () (at Assets/Scripts/PlayEatingSounds.cs:30)

At line 30: audioSource.clip = audioClips[Random.Range(0, audioClips.Count)]; The list with audioclips is definitely not empty. I have 0 clues or google results in how to tackle this, please help.

 public class PlayEatingSounds : MonoBehaviour
 {
     public Vector2 pitchRange;
     public List<AudioClip> audioClips = new List<AudioClip>();
 
     private AudioSource audioSource;
     private AudioClip audioClip;
 
     void Start()
     {
         audioSource = GetComponent<AudioSource>();
     }
 
     public void PlaySound()
     {
         PlayList();
     }
 
     public void StopSound()
     {
         CancelInvoke();
     }
 
     void PlayList()
     {
         audioSource.clip = audioClips[Random.Range(0, audioClips.Count)];
         audioSource.pitch = Random.Range(pitchRange.x, pitchRange.y);
         audioSource.Play();
         Invoke("PlayList", audioSource.clip.length);
     }
 }

if The list with audioclips is not empty, maybe audioSource is empty? Try to specify it in the inspector instead GetComponent
