Changing AudioSource.clip causes click/pop sound

Hi All, I've had this problem for a while now, and have not had much luck finding a solution.

I have a script attached to a gameObject called BGM.cs. In this script, a coroutine is started that picks a random AudioClip from a List and plays it. After a time delay it then plays another random clip.

Here's the play code:

 // get the track from the playlist
 AudioClip clip = tracks[CurretTrack];
 
 // stop the audioplayer first (may cause Pop noise if clip is changed 
 // while playing) <-- Did not work
 musicSource.Stop();
 
 // set the clip and play it
 musicSource.clip = clip;
 musicSource.Play();
 
 yield return new WaitForSeconds(time);

I am using MP3 music, and I have also noticed this with other audio assets in WAV, only when stopping or changing a clip.

I uploaded an example of the set-up and the bug to YT: https://youtu.be/G074KSn9IxE

If anyone can help me with this, I'd really appreciate it :)
