How to register earphones in a different jack?

January 27th, 2013 Leave a comment Go to comments

My earphone jack is broken, has been for a while, but my microphone jack is completely fine.

A while back, I once plugged a pair of headphones that also had a microphone into a computer. I found the microphone came out much clearer when I switched them round (microphone into earphone jack, and vice versa) and it registered instantly on my computer.

The computer can’t tell the difference between a microphone and an earphone, but one is an input socket and the other an output socket. The microphone circuit may be able to amplify sound from headphones because speakers and microphones are similar devices, but you can’t just plug headphones in the microphone socket and hope the microphone circuit will magically change into an amplifier. You need to get the computer repaired, it may be a broken earphone socket or something else may be wrong.
