Windows 10: Mic audio not detecting on only one earphone

I was using Mi Dual driver wired earphones in my PC for a long time and 2 days before, my mic is not working well. My voice is not getting recorded. Some small grains are present and if I press the mic buttons, the button sounds get recorded but nothing else gets inputted to my PC. The same earphones work well with my phone and other PC. Also I have other earphones which work very well in my PC. I am really confused.. What is wrong with this particular earphone? Help please?

Earphone mic not being detected

Hi, I have an Acer Nitro 5 AN515-52 with a single audio jack for sound+mic. I have Windows Audio driver because Realtek did not detect my headphones at all. Now I can only see my headphones as an output device but no input device at all but my earphones have a built-in/inline mic. I checked in the sound devices in the microphone tab but there is no headphone microphone (enabled option to show disabled devices). Please help.

Maybe as a work around you could use a Y spliter. Where you plug in your headphones into it and the other ends will go in your mic and earphone ports on your pc/laptop. Yes i understand they are combo ports but i'm just suggesting this as a workaround till you can find drivers that makes the combo port work correctly.
Here is the cable i was talking about. You don't have to use it but just a suggestion as a workaround and as a last resort.

There is only HD audio manager app, I set it as headset there. Oh and by "apps like zoom and ms teams work fine." I meant they use the earphone mic and not the internal mic but the voice changer app uses internal mic.

Also, when I use Windows HD Audio drivers, they show "Headphones" as output audio devices but nothing in input devices.
