Question Computer doesn't recognize headphones

[Lilla]

Hi, i got a problem with my monitor. I use headphones that include microphone and it actually works fine, but my microphone doesn't work. The headphones are good, i tested on another devices and the mic too. I tried to restart everything, update the drivers etc... But my pc doesn't recognize the actual headphones, only the monitor,. So if i jack my headphones into the monitor, i can hear everything trought the headphones, but i can't use the mic and this is a problem i searched long, but didn't find solution. (the headphones and the monitor is relative new and this problem were in the beginning too)info about computer and monitor:
GPU: NVIDIA GeForce GTX 1650
Processor: AMD A-10-7700 Radeon R7, 10 Compute Cores 4C+6G
