How can I get the string name of the current snapshot of my AudioMixer?

This documentation is not very helpful

That’s for Finding a Snapshot by it’s name e.g:

using UnityEngine;
using UnityEngine.Audio;
public class FindSnapshot : MonoBehaviour {

	AudioMixer audiosnap;

	void Start () {
		audiosnap.FindSnapshot ("MySnapShotName");
	}

}
