Headset is working but does not work with the controller

The adapter mentioned in link is optional and the update to the controller can still be installed. It's mentioned to attach adapter so it is updated as well.

The adapter bypasses the headset socket on the controller which can become faulty over time, eg loose fitting. It also gives you volume controls at your fingertips and is worth purchasing.

If you decide to purchase an adapter, run the controller firmware update again (see link above).

But what if I don't have an adaptor? I don't think I have one. So is there any other possible way that could work.

Follow the steps in this support page, Update xbox wireless controller. This needs to be done on all controllers you may use. The uSB method is my preference.

Will need some more info, what is the make and model of the headset

Has this worked the past.

Does the headset portion work correctly, in other words do you just have an issue with the mic.

Can you try another controller, or better yet try using the headset on a friends xbox or take it to gamestop

If the headset works on another controller then it may be an issue with the controller or console, if this headset does not work with another controller, then it may be an issue with the headset.

Not all headsets are supported with the xbox

Hi, thank you for the response. Yes, the headset and mic work with another controller with an older firmware.

The headset, once plugged into the controller with newer firmware, there is absolutely no audio from anything and the mic does not work. The controller does not recognize the headset at all.

Please note, the controller in question is a customized controller from Microsoft.
