MBP - Switch back to built-in microphone I have some Apple earplugs with a broken microphone, therefore I cannot talk. I would like to switch back to the built-in microphone. However, there is no option to do so in the Sound System Preferences, and only this is shown:



And if I unplug the earplugs, I only see the built-in microphone.



How can I switch to the built-in microphone, when I connect the earplugs?
Apple headphones, works
as Combo Jack, ie ear headphone + microphone
external, so you'll have to use another headset.
give it a try.
