So i have the like basic corsair headphones, that has the attachable mic. When i first got them i plugged in the splitter cable (green to green, pink to pink) and had no problems with the audio or the mic, but its been 3 months since and now the mic randomly stopped working. Everything is plugged in double checked that many times. My computer's mic permission is on. I tried a few other things and i haven't been able to get it to work. What can i do? help would be greatly appreciated. thank you
