The thing is you cant have it fade with that function cause it will only run once. You need it to run in the update function. void Update() { if (On) { currentVolume = Mathf.Lerp(currentVolume, 1, .125f); }

      if (!On)
      {
          currentVolume = Mathf.Lerp(currentVolume, 0, .125f);
      }
       _Source.volume = currentVolume;
  }
