2nd Audio Clip Not Playing

My Debug line is working so I know it's reaching that pint but for some reason the audio clip does not play? Here is my code:

 using UnityEngine;
 using System.Collections;
 
 public class MicroJamSwirlManagerScript : MonoBehaviour {
 
     // Sound FX Array
     public AudioClip MicroJamSwirlFX;
     public AudioClip KITTVoice01;
     public AudioClip KITTVoice02;
     //Assign Animation Controller
     public Animator MicroJamSwirlAni;
 
 
 
 
     void Start (){
         //initializes micro Jam Sound FX
         audio.clip = MicroJamSwirlFX;
         audio.loop = true;
         //audio.Play();
 
         audio.PlayOneShot(KITTVoice01);
 
         //Start Animation Delay
         StartCoroutine(Wait());
         StartCoroutine(Wait02());
 
         StartCoroutine(LoadAfterDelay2("KnightSpinningLogo_NoKITTintro"));
         //initialize Micro Jam Animation Loop
 
         //MicroJamSwirlAni.SetBool("MicroJamSwirlOff", !MicroJamSwirlAni.GetBool("MicroJamSwirlOff") );
     }
 
     public  IEnumerator Wait(){
         yield return new WaitForSeconds(1.5f);
         MicroJamSwirlAni.SetBool("MicroJamSwirlOff", !MicroJamSwirlAni.GetBool("MicroJamSwirlOff") );
         audio.Play();
     }
 
     public  IEnumerator Wait02(){
         yield return new WaitForSeconds(2.1f);
         audio.PlayOneShot(KITTVoice02);
         Debug.Log("exicuted This Line");
     }
 
     IEnumerator LoadAfterDelay2(string levelName){
         yield return new WaitForSeconds(5.5f); // wait 1 seconds
         Application.LoadLevel(levelName);
         
     }
 }
