So your Headset works for Audio, but Mic doesnt work.
When you go into audio properties is the mic there or does it show its missing or greyed out?
I looked at asus website and didnt see any drivers for it, but if your headset came with a CD driver for it, you can try pushing that driver to the system and use Windows 7,8, or 8.1 driver on 10.
I had a similar problem years ago when going from XP to 7. Lost my mic jack on my motherboard. Tried drivers for realtek and it would install and say all is well, but no mic. The mic only worked under XP yet audio out worked fine. I got frustrated and just bought a USB 5.1 Audio adapter and used that, however your headset I believe is just a USB plug and not audio and mic independent phono jacks.
