Windows 10: Realtek High Definition Audio High Pitched noise

There's a loud high pitched noise coming from the microphone that nobody can hear what I say. The troubleshooter cannot pick it up. When I use my ear buds, the microphone works. When I take it out, there's just static and my voice is not heard. This problem comes and goes randomly. I don't know how to fix it. I think my all drivers are updated, not sure.

High pitch noise - microphone Realtek high definition audio

Help needed, please.

Week ago, while skyping, a very high pitch sound started. I had to stop skyping not to damage everyone's hearing. I found out that it was the mic (realtek) that was giving this very disturbing noise. I updated the drivers, not successful. I had to mute
the microphone to stop the sound.

I cannot do any internet conferencing at the moment. I can hear and see but, of course, not speak. I have Windows 10 and Asus ZenBook (11/2018 -).

What should I do next?

I would really appreciate help and advice!

 

Realtek High Definition Audio not working

First of all, the Realtek High Definition Audio Device did not automatically reinstall after uninstalling and rebooting. I had to go into Add Legacy Software and select it to install. The Device Manager crashed while installing it, which it always does.
Upon starting it up again, the Device is there, but with a warning sign next to it indicating it is not functional.

Second of all, when I did the rest of the steps, the Driver Manager told me specifically that the drivers for Realtek High Definition Audio Device are up to date.

Thank you for trying to help so far btw
