Windows 10: Why isn't my wired headset microphone detected?

I have seen many questions like this, and many answers that don't work. I really, really want an answer as to why my wired headset microphone isn't detected. It's worked before, but it doesn't seem to be working now. I have been troubleshooting for hours, and I'm a hair away from taking full advantage of my laptop's warranty. I will list my dead ends that I have went through trying to solve this issue.According to my system and Windows support, all of my drivers are up to date.According to windows, my headset also does not require external drivers to operate.Because my microphone has worked on

laptop not detecting headset microphone

I want to use the microphone attached to the headset as I just bought the headset but my laptop is still using the built-in mic and the headset mic is not detected.

 

laptop not detecting headset microphone

I recently bought a new headset with a microphone and I can hear audio through the headset but
my mic is not detected and it is still using my default Realtek computer microphone.

I've tried looking for hidden microphones but there are none.
I've re-installed my Realtek HD Audio driver.

But nothing seems to work.

What should I do to fix this?

 

Computer won't recognize headset microphone

This is what i see in device manager. Im not sure if the Speakers/Headphones (Realtek High Definition Audio) is the one your saying to disable, as that is what is default in playback devices in the sounds panel.

Setting Stereo Mix as the default recording device and disabling everything else still didnt get the mic working, even when the headset is plugged into the microphone only audio port or the mic + sound audio port.
