Shoott i don’t know thats tuff. I would have to just create something to at least hit the latch in order to stop the music. But the warble sound is most likely the speed of the player. You need to ajust the speed. By the battery comparment you’ll see a brown motherboard and next to the battery component. There is a sliver weird thing standing up. U turn that to ajust the speed . I hopeeeee that helps it' was tuff explaining.
