Headphone jack doesn't work

Jack silences speakers, but no audio in headphones. Checked headphones and they're OK.

MacBook Pro, Mac OS X (10.7.3)

You may also want to open the Sound pane in System Preferences, click on the Output tab and confirm that the system is detecting the presence of the headphones.


True dat, although it would seem it's being recognized because the speakers cut out. In any case, thanks for the help. 😉

Tried wiggling. No go. Also this is an instance of working one day and then suddenly not working the next.


Even though the wiggling isn't working, this behavior makes me think of the switch even more. Sometimes there are very minor differences in the plugs. Do you have another set of headphones to try? Also try inserting very slowly and stopping just before it's in all the way. Also try pushing just a bit harder to make sure the plug is in all the way.

Tried another set of headphones but still not working. Seems like the same mechanism that cuts the speakers should send signal to headphones. May need to call support. Had another issue with the optical drive on this six month old computer. It required replacement.


Given that you're still under warranty, that's definitely the right call.

This happens when you update the OS. Shutdown Macbook Pro, after it shuts down, press Control + Option + Shift at the same time for 30 seconds (it would appear that nothings going on). After the 30 seconds press the power button, log in to your account, play media on the speakers, then plug in your headphones to verify that the hardware(headphone jack) is properly working.


If this doesnt work, and the diagnosis test shows no problems in your computer, then take in the MPB for a checkup at your nearest genius bar.
