I broke the headphone jack of my MacBook, so now you only hear the right-side, even with mono-audio on. But when I unplug the headphones, the speakers are turned off and only Digital-Out can be seen in the sound settings.
But the weirdest thing is in Ubuntu or any other OS the speakers work, headphone still only one side, but it works. But on Mac OS even a other Hard Drive it does not work. Only the startup chime works. For the record there is no red light in the headphone jack. Probably physical damage inside the jack.
Any way I can make the speakers also work in MacOS again?
