USB C to 3.5mm headphone adapter not working correctly.

I am using an apple USB C to 3.5mm headphone adapter with a lavalier mic. It was working at first, but not working any more. My computer recognizes the mic in the "output" but not in the "input". I need to select it as input to use the mic on Zoom calls. Please advise.

Hello rrejino,


Thanks for using Apple Support Communities! We see you're having an issue with the USB-C adapter with your Mac. We'll be glad to assist.


We have a couple of settings you can check on your Mac to help get this fixed. Please follow the guidance from both links:


If you're continuing to experience the same thing, try restarting in safe mode: How to use safe mode on your Mac - Apple Support

This will start up your Mac so that it performs certain checks and prevents some software from automatically loading or opening, which could help narrow down the cause of issue. After testing in safe mode, restart your Mac normally to see if the behavior continues.


Have a great day!
