computer won't recognize microphone on headset

[Brandalf]

hi, i used to be able to use the microphone that was on my headset but now my computer doesn't recognize that it even has a microphone anymore and i went into recordings and it says nothing was plugged in but when i put my headphones in the microphone port then it recognizes it, i think the reason its doing this is because my computer thinks its now just headphones and not a headset with a microphone but idk how to change it.

Is this with a 3 pole (both headset and mic) or with two two pole (either headset or mic) socket?
