Check any audio isPlaying

Hi guys, is there a way to find out whether any audio is playing?

 var otherClip : AudioClip;
 
 function Update (){
     if (!audio.isPlaying){
         audio.clip = otherClip;
         audio.Play();
     }
 }

This works only when the script is attached to the gameobject that contains the audio source. If I want to target to another script in another gameobject, i can do this.

 if (gameObject.Find("text01").audio.isPlaying) {
 
   dosomething();

}

But what i really want is to check if any sort of audio is playing in the scene. It can be playing from any gameobject with a audio source attached. If there a way to check it? Sorry for the long winded question. Trying to get my question across as clear as possible. Thanks guys!!
