**The video that you posted here also helped me, together with the 1st comment (from user Insp3ctorJon3s) on the video. *Found that link on the second answer from Headset microphone not working on Ubuntu 20.04. Next time I plugged-in the headset, I got the window asking me Select Audio Device (Headphones / Headset).

If the input sensitivity is too high then the microphone could be overloaded and hence could be providing poor audio which could be interpreted as the microphone being faulty. If the input sensitivity is too low then the device you are connected to may have trouble detecting the microphone which could be interpreted as the microphone not functioning.

It is also recommend that you check the microphone input sensitivity to ensure it is set appropriately. For example on a PC you would go into the "Control Panel" and into "Audio Devices/Settings" (or something similar) and select the headset as the play back and/or communication device. NOTE: Usually this is done within the settings of the device you are connected to. When the microphone of your headset does not appear to be functioning correctly it is recommend that you check to ensure that the microphone is actually selected as the input device. What do I do if the headset microphone is not functioning correctly?
