12V through headphone jack (Mac)

Recommended Posts

Posted · Original PosterOP

Long story short, I accidentally sent 12V DC through the headphone jack on my MacBook Air. I am pretty sure I fried some components regarding audio because the audio device doesn't even show up anymore, and when I plug in headphones it's a repeated clicking sound. I can't raise or lower the volume either, whenever I try it just shows the prohibitory icon. Yes, I have restarted the Mac, no success. Someone help!

Have you tried buying a new mac from Apple.com?

It's probably toast. Time for some BT headphones or an external DAC.

Your only alternative at this point is a USB audio adapter or BT.

 

I did the same thing where I accidentally sent 48V phantom power from a mixer to my Macbook air headphone jack because I was playing around before and forgot to turn it off oops. The system doesn't detect the device at all. My BT audio doesn't even work consistently it will cut out after about 10 minutes of use and I'll have to reconnect the device.

Long story short, I thought an input on another device was an input, it wasn’t... it was an output........

I was thinking about using a USB adapter, HOWEVER, it turns out my issue is worse than I thought... I fried my USB ports too, I have no idea how, but there is no activity on either port.
