subwoofer turns on and off
My macbook pro seems to be having an issue with the subwoofer going off and on. I have checked all connections to the logic board and everything seems good. both left and right speakers work fine. I have noticed that when i tap on the back of the laptop, sometimes this helps and the woofer will turn on for a while, then it turns back off. Do i need to replace this?
Is this a good question?
