Headset and mic not working through Xbox controller on pc.

Please help!!!... I have an Xbox one wired controller plugged into a usb socket on my pc. I then have my headset and mic plugged into the socket on my Xbox controller. I have sound but no mic.... This works on my Xbox laptop and on my phone so it's not the headset. Been through lots of settings in my pc. No joy..:(. Does the headset lead have to be split into mic and headset for pc????. Thanks.
