Headset Adapter doesn't work with my new controller

Old controller required the stereo headset adapter to work with my headset. ( was a friends stereo headset adapter) so I thought i'd buy the new type of controller so as to not also buy the stereo headset adapter.

The new controller differences

3.5mm jack which is pointless

and the bumpers feel slightly different, but that just may be because i'm now used to worn bumpers on my old controller.

that's it

My X1 headset adapter stopped working on 10/27. No mute light and no mic getting to Xbox. The mic works, I can hear it in the headphones, but it's not getting through adapter. I tried updating controllers, but they didn't update.

I went out and bought another X1 headset adapter, controller auto updated, new adapter works fine, old one still doesn't. Too soon for this stuff to brake down. I want warranty or reimbursement to kick in here. Help!

If your Xbox one Controller doesn't work or gets disconnected after you plug in your Stereo Headset Adapter, unplug your adapter,
and then update your controller without the adapter. After the controller is updated, insert your Stereo Headset Adapter back into the controller.

funny

I have a similar problem see below

Xbox one original controller, stereo headset adapter and headset and I can hear in game chat but as soon as I connect to party chat, they can hear me but I cannot hear them. I tried the original headset that comes with the xbox one and it worked so I figured
it was the stereo adapter. so I purchased a new stereo adapter and have the same issue. so I purchased a new controller with 3.5mm jack. I have the same issue. but if I use my headset connected to the 3.5mm jack on the new controller party chat works fine,
but doesn't work connected to stereo adapter (and I tried 2) So I thought I would try on my sons xbox one (we have 2 xbox ones in the house) so we swapped headsets , controllers and stereo adapters and I had the same problem on my xbox one. whereas his was
working fine (and he was using my controller, headset and adapter) So it would seem to be an issue with my console, that is the only hardware difference. any ideas?

That doesn't work. A gamestop employee told me the X12 won't work on new controllers because it's analog and it only works with digital or something... does anyone know, if I buy the (overpriced) headset xbox one headset adapter will it work then?
