Why is my right speaker whining?
So I decided to pick up a very cheap macbook pro that had a graphics issue. I repaired it and gave it a cleaning. I tested it with the keyboard unscrewed from the unit and all the speakers worked fine. But when it is screwed down and complete, the right speaker makes a whine on bootup and will whine if I adjust the volume and play a sound instead of playing the sound. the left speaker if perfectly fine. Any help?
Cette question est-elle utile ?

Sorry for the wait, yes it was a pinched wire somewhere. No clue where it was but I had to take the logic board out anyway so I took a look. Still don't know where it was pinching or crossing.
