Trigger audio clip on load level async (only playing for a fraction of a second)

Hello,

I want to play an audio clip once I set a level to load (using loadlevelasync), but am struggling to get this to work.

I'm checking to see if a bool is set to true in the loadlevelasync script: at which point I want the audio clip to play.

However - I'm having the problem that it's playing for a fraction of a second once the bool is set to true. Then you can't hear the audio clip, and then once the new level is loaded you can hear the clip.

If I call the audio clip from a key press and then load the level at the same time, then I can hear the audio clip whilst the async load is happening, so I don't think it's because it is freezing. (And other audio clips are still playing).

Does anyone know what I might be doing wrong? (Or if I should go about this in a different way?)

 using UnityEngine;
 using System.Collections;
 
 public class DontDestroyLoad : MonoBehaviour {
         
     public GameObject[] musicSwipe;
     GameObject levelLoaderObject;
 
     void Awake(){
         DontDestroyOnLoad (this.gameObject);
     }
 
     void Start () 
     {
         musicSwipe= GameObject.FindGameObjectsWithTag ("AudioSwipe");
 
     }
 
     void Update()
     {
         if (Application.loadedLevelName == "Title")
         {
             levelLoaderObject = GameObject.FindGameObjectWithTag ("LevelLoader");
         if (levelLoaderObject.GetComponent<AsyncLoad>().levelTrue == true)
         {
                 print ("playing?");
             StartCoroutine(PlaySwipe());
         }
         }
     }
 
 
 
     IEnumerator PlaySwipe () {
 
         if (musicSwipe.Length == 1 ) 
         {
             GetComponent<AudioSource>().Play ();
         } else {
             for(int i = 1; i < musicSwipe.Length; i++){
                 Destroy(musicSwipe[i]);
             }
         }
         yield return null;
     }
     
 }

Best, Laurien
