audio source on instantiating game object

Hey guys so I have this code and it is added in a game object i am instantiating But when the object is instantiating i get the error "cannot play a disabled audiosource" How can i make it work without changing the audiosource from where it is now?

 using UnityEngine;    using System.Collections;
 
 
  namespace DigitalRuby.PyroParticles   {
      /// <summary>
      /// Provides an easy wrapper to looping audio sources with nice transitions for volume when starting and stopping
      /// </summary>
      public class LoopingAudioSource
      {
          public AudioSource AudioSource { get; private set; }
          public float TargetVolume { get; private set; }
  
          private float startMultiplier;
          private float stopMultiplier;
          private float currentMultiplier;
  
          public LoopingAudioSource(MonoBehaviour script, AudioSource audioSource, float startMultiplier, float stopMultiplier)
          {
              AudioSource = audioSource;
              if (audioSource != null)
              {
                  AudioSource.loop = true;
                  AudioSource.volume = 0.0f;
                  AudioSource.Stop();
              }
  
              TargetVolume = 1.0f;
  
              this.startMultiplier = currentMultiplier = startMultiplier;
              this.stopMultiplier = stopMultiplier;
          }
  
          public void Play()
          {
              Play(TargetVolume);
          }
  
          public void Play(float targetVolume)
          {
              if (AudioSource != null && !AudioSource.isPlaying)
              {
                  AudioSource.volume = 0.0f;
                  AudioSource.Play();
                  currentMultiplier = startMultiplier;
