So when i first bought the speaker it worked perfectly, up until now. It just suddenly stopped working. So i turned it off and on again. Usually the startsound is about 4 seconds long, but after about 2 seconds there is a crack and won´t continue playing. This happens everytime i turn it on again, so the speaker in itself isn´t the problem. I Factory reset it multiple times without any result. Also the speaker is connected since i can use the play and louder buttons and they work. Do i just have to send it back?
