Now, yes, I can disable this pop up, but that setting is never saved, which means whenever I plug the earbud in, the system will disable my laptop's mic. Here I can select to ignore the earbud's mic, but this is not a great choice because every time I plug it in, that thing pops up, which is not good while gaming, for example.
Anyways, to achieve my desired setting I need to have this pop-up enabled for whenever I connect an audio device it asks me what it is. I don't know why, I guess it has something to do with earthing/grounding but that's not the point here.
The earbud's mic is noisy on the PC despite it working great on my phone this happens with other earbuds too. The mic on your headset won’t work if you’re using an incorrect or outdated audio or headset driver. The problems can arise due to a damaged port, plug or cable. The headsets are the most prone to damage in a PS4. You may want to check your hardware in this case. If it does, then you’ve solved the problem. Check for any Hardware issue : Your PS4 was working fine until now, but all of a sudden, stops functioning.
That's not good because my laptop's mic works better for some reason. Now that the microphone of your headset is enabled and set as the default device, and you’ve turned up your microphone volume, try it and see if it works. I have a laptop with combo audio jack, which means whenever I plug an earbud that has a mic, the machine will automatically detect that mic and disable the laptop's internal mic.
