My motherboard is asus b450-f, it has five audio ports and according to the manual, three of them are used for speakers, one for headphones and another one for microphones. For gaming I usually just use the headphones that came with my old Iphone 5s, it has worked peferctly fine. Nevertheless, in this new computer the microphone of the heaphones just stopped working, although the audio is fine. I've tried the audio drivers from asus website but it doesn't work either. Please help me if you guys got any solution, thanks in advance.
