Working between different scenes!

I have a gameobject on Main Menu that contains a muted Audio Source. When I $$anonymous$$t the Level 1 button, the Audio Source is unmuted and the music starts playing. Also, for t$$anonymous$$s to happen the gameobject has "DontDestroyOnLoad".

Now I want to go back to the Main Menu by pressing another button, and I want the Audio Source to mute again. The t$$anonymous$$ng is I'm not able to mute it, because I tried working with the "OnClick()" of the "Main Menu" button (the one that brings you back) to mute it, but I can't reference the gameobject because it's not on Level 1 yet! What I also tried was to order the Audio Source to mute when "button" is pressed, but I can't reference to the "Main Menu" button because it's on Level 1 :s (and gameobject is on MM).

I'd accept a workaround if t$$anonymous$$s is really not possible.
