Hello. I been searching all day for a fix. I tried everything I think. My problem is I have a ear force x12 headset I use it for my laptop. My laptop has one jack that is headphones/microphone and I only have to plug the green audio in and the usb and it use to work fine. I could hear audio thru the headphone and use the headphones MIC with no problems. Not fully sure what has happen but now the MiC does not work. When I am in the sound setting under recording devices it's there. If I have only the green pluged it witch works as a MiC jack aswell it shows connected but right when I plug in the usb to power the headphones the MiC stops working. Use to work fine. Now it's messing up. Any ideas?
