how can i fix the sound of my oontz angle 3 but it is connect in bluetooth then when you play a music no sound come out,

im having the same issue, i used my oontz to play music at night and had it run for several hours at a time. this has led me to believe after reading the user manual that the speaker has burnt out and needs to be replaced. but i have no evidence to prove this theory. best of luck just another hobbyist
