Microphone does not work when headphone is plugged in

[MatteP]

Hi everyone,

I don't know why but suddenly my microphone has ceased working when my earphones are plugged in (which, as you can guess, is rather troublesome during a videocall).

It works fine when my earphones are unplugged but when I plug in the earphone, the microphone stops working.

I tried using alsamixer but I see no difference in the mic settings between plugged and unplugged.

Any help, please?

Thanks
