Making Enemy Audio quieter

How do I make the audio from a enemy fade away as i move further away from it?

I’ve tried to use the 3D sound settings in the audio source but the enemy audio is the same no matter how far away it is from the player

3D audio definietly works, your settings may be wrong, you should check that.

Outside of that, AudioSource has volume property you can use. Just get Vector3.Distance(Player.transform.position, Enemy.transform.position) and set volume based on that.
