Hi! I'm Rostom, an Independent Advisor. I will be glad to help you here.

May I exactly know your headset and controller make/model? What's your Xbox console model or generation as well?

When did this issue start to occur? Have you tried some troubleshooting steps already?

Make sure that your headset and controller firmware are up-to-date.

I’ve had the same problem. I would connect the headset into the controller if it has a cord and turn it, sometimes it worked for me and sometimes i had to push it harder into the controller. In the end I still had to buy a new headset unfortunately.
I had a hyper x cloud 9 headset and the mic broke, so i went on amazon and purchased a peozarr headset and it has the best sound. It is like $25, but they will send you a card to where you get another item of your choosing including a headset.

Thank you so much for the reply, but the headset works fine. This morning, my controller again gave zero problems, but still no sound comes out of my girlfriends'.

None of those troubleshooting steps are appropriate to my situation. As evident from the fact that sound plays out of other connected listening devices, there is no issue in my sound settings; and I cannot change the volume or similar, as the device and
accessory settings are not acknowledging that there is a headset connected (and there is sound when connected to other headsets). I am aware that this option appears below "buzz" in the device and accessory settings.

It is not that the mic is not recording, or that sound is not coming through the headset, it is that the controller won't recognise that there is anything plugged in when combined with my headset (even though it can recognise other devices, and the headset
is working).

Thanks anyway.

check your entire headset wire for any breaks or wires showing, as stated before it will not matter what usb port you plug the controller into. also check the ear piece on your headset as sometimes they can become temperamental and break (i have had this
happen to me on several very expensive ones!) check your sisters controller with your headset aswell and vise versa your controller with her head set. hope this also helps

OK. I'll investigate it more.
