When I plug in a headset with mic into the 3.5mm jack, the audio is OK, the microphone does not work. How to fix this issue?
If you use Windows, in the settings, check that the microphone is selected and how it works. For drivers, updating with Driverscloud is recommended. https://www.driverscloud.com/en
Thanks. I chose the microphone as the input in Windows Sound Setting. I also reinstalled the driver. The issue is still there.
Maybe just a headphone output?... Could you try an USB adapter to be able to use the mic? 
I guess so. I now go with a Bluetooth headset as the workaround.
@Jack Chen Could you please explain the process you used to make your microphone work with blutooth? I have the same problem with a Maono USB lapel mic that actually turns the computer completely off every time I plug it in and I have to wait for 2 minutes before the computer comes back on.
