Headset microphone not working

Hi, I’m using Arch Linux on a Asus Chromebook Flip, I installed the audio script and everything seems to be working fine, audio works and the built-in microphone too, also when I plug in my headphones they work, the only thing is that it doesn’t seem to recognize my headphones mic, what can I do to fix this?

When you go to the sound option do you find two option there?

I’m connecting it through jack
I see this in pavucontrol


my headphones are the second one, Controller Pro 1 it works

But in input devices only my laptop’s microphone works

provide me the ss of input device

alr

If you talk connecting your head set do you see any other blue lines fumbling except controller 99? If you notice any controller doing the same select the controller and the mic of your headset should work

I tried this and it doesn’t work with any device, except 99
