Usage of DownloadHandlerAudioClip.streamAudio

Question

Hi all,

I am trying to start playing an AudioClip before it has been completely download as $$anonymous$$nted at in the documentation for DownloadHandlerAudioClip.streamAudio. I have written t$$anonymous$$s sample code to illustrate the use I would expect to work:

     private IEnumerator StartAudioStream()
     {
         // Prepare stream
         string url = "www.brainybetty.com/FacebookFans/Feb112010/C$$anonymous$$llingMusic.wav";
         DownloadHandlerAudioClip downloadHandler = new DownloadHandlerAudioClip(string.Empty, AudioType.WAV);
         downloadHandler.streamAudio = true;
         UnityWebRequest request = new UnityWebRequest(url, "GET", downloadHandler, null);
 
         // Start stream
         UnityWebRequestAsyncOperation token = request.SendWebRequest();
         AudioClip audioClip = null;
         w$$anonymous$$le (audioClip == null) // Ensure audio header completed
         {
             try
             {
                 audioClip = DownloadHandlerAudioClip.GetContent(request);
             }
             catch (Exception) { }
             Debug.LogFormat("Waiting for AudioClip: bytes={0}", request.downloadedBytes); // The complete file is 4834942 bytes
             yield return 1f;
         }
 
         // Play AudioClip
         source.clip = audioClip;
         source.Play();
 
         yield return 0;
     }

Thank you in advance for your time.

 private IEnumerator LoadAudio(string audioName, int track_id, float start_time)
 {
         using (UnityWebRequest www = UnityWebRequestMultimedia.GetAudioClip(
                                         musicPath.Replace("#","%23") + 
                                         //musicPath + 
                                         audioName, AudioType.OGGVORBIS))
         {
             
             var synRes = www.SendWebRequest();
             yield return synRes;
 
             if (www.isNetworkError)
             {
                 Debug.Log(www.error);
             }
             else
             {
                 stream_music = DownloadHandlerAudioClip.GetContent(www);
                 musicSource.clip = stream_music;
                 musicSource.time = start_time;
                 current_track_num = track_id;
                 current_track = GetCurrentTrack();
