Hi, @3dguima..
I use a simple puzzle and a couple of objects to control the sound. I did a screenshot where you can see the puzzle as well as the sound controls I made in Blender… This plays “tunes.mp3” in the application directory folder (or whatever your filename is).
I’ve made a couple a bit more complex but with this same logic – but this has all of the basics.
I’ve attached the image. I hope this helps.
