Error FMOD::Sound instance - no sound is being played from AssetBundle

Hello, I would like to ask help regarding my audio issue, I'm currently using Unity 5.4.4f1.

A problem occurs when streaming audio assets from the AssetBundle - No sound is being played even if the clip is being loaded to play the audio.

The Error message displayed in Unity Editor::

 Error: Cannot create FMOD::Sound instance for resource archive:/CAB-a61ecea0bd4cf006255ec4fbd69f005a/CAB-a61ecea0bd4cf006255ec4fbd69f005a.resource, (File not found. )
 UnityEngine.AudioSource:Play()
 <ChangeBGM>c__Iterator166:MoveNext() (at Assets/Scripts/Shareds/SoundManager.cs:357)

Once the new audio asset from AssetBundle gets streamed. the error above is thrown when Play() is called.

Below is my ChangeBGM method where I call Play():

 IEnumerator ChangeBGM(ChangeBGMSettings settings)
     {
         var fade = settings.fade;
         var source = fade.source;

        StartCoroutine(Fade(source, fade.outTime, source.volume, fade.targetVolume));
         yield return new WaitForSeconds(fade.outTime);

        source.Stop();
         source.clip = settings.clip;
         source.loop = true;
        
        source.Play(); //this is where problem occurs

        StartCoroutine(Fade(source, fade.inTime, source.volume, 1));
     }

This error happens intermittently and when this happens, no background music plays.
