Universal sound control across each scene

I am making a game in which I want to set the volume level at the start screen. I've placed a checkbox to enable/disable sound. After searching on how to set the sound control over all scenes I got to know about DontDestryOnLoad method. I am using it now to save the gameobject containing both the audio listener as well as audio source. Its working fine but the problem is when I beat the 1st level I want the audio to change and play the BeatLevel SFX which I've set in the game manager of the Level 1 scene. In the Level 1 scene I've an audio listener attached to the main camera and in GameManager I've set Background Music to None (as I'll get this music from the start screen audio source which I didn't destroy) and BeatLevel SFX to some victory sound but its not playing after clearing the level.

Please Help. Thank You
