If all you do is change the "sound type" (sound effect/music), you must manually save the game to save this change. If you just 'x' out of the sound resource, Stencyl will not automatically save the sound resource.
This is very important, as there is a big problem with too many sound effect type sounds being loaded in at the start of a scene. It can cause a crash, especially if the atlas RAM usage is high (for me, it's if the atlas RAM requirement is > 450 MB)
