A buddy of mine has a MacBook Air (late 2013) A1466. About 2 days ago, the audio was fine. Now it won't recognize the audio devices at all and there's a loud feedback sound when you plug in headphones. He is a Fire Chief and he uses this for presentations, so he definitely needs audio back. Any ideas?
tried to conect audio via usb?
For example: I have a external mic that conects via USB. I can plug in my earpods directly into the mic. Maybe try something like that? Then u know if it is the audio card of the laptop or something else.
