Stereo Headset Adapter not Detected in Controller

Hi Clare,

Thanks for coming to the forums with your issue. Unfortunately, that symbol means the controller is not detecting the headset. It is not a mute icon. Try updating the controller with the headset plugged in. You can also try a

stereo headset adapter.

Thanks,

Brad

Stereo Headset Adapter issues and questions

If you have a question or problem using the Stereo Headset Adapter, see the following topics.

Stereo Headset Adapter isn’t working

If your Stereo Headset Adapter isn’t functioning well, check the following:

Have you updated your controller’s software to support the Stereo Headset Adapter?

Make sure your controller has fresh batteries. When the batteries get weak, some controller functions like audio and rumble get turned off to conserve the remaining power.

Make sure your headset adapter is firmly plugged into your controller and that your stereo headset’s 3.5-mm cable is securely plugged into the headset adapter. You will know it’s plugged in properly if you press the mute button and the LED lights up.
If the mute light comes on and you have updated your controller but your headset isn’t working, consult the manual or manufacturer.

Try your Stereo Headset Adapter on another controller if you can. If the adapter works on the second controller, try updating the first controller again. If that fails, the controller will need to be replaced. To order a replacement, go to the Xbox Online
Service Center.

Hi there!

Thanks for reaching out! I'm sorry to hear about the issue with no headset being detected on the console.

I recommend to take a look at the following troubleshooting resources:

• Have you
  updated
  your controller’s softwareto support the Stereo Headset ?
• Make sure your controller has fresh batteries. When the batteries get weak, some controller functions, such as audio and rumble, are turned off to conserve the remaining power.
• Make sure your Headset Adapter
  is firmly plugged into your controller and that your Stereo Headset’s 3.5-mm cable is securely plugged into the Headset Adapter. You will know it’s plugged in properly if you press the mute button and the LED lights up.
• Try your Xbox One Stereo
  Headset with another device, such as a laptop, to see if the headset is working. If not, the headset will need to be replaced. To order a replacement, go to the
  Xbox Online Service Center.
• Try your Stereo Headset and
  Stereo Headset Adapter on another controller, if you can. If the headset works on the second controller, try
  updating
  the first controlleragain. If that fails, the controller will need to be replaced. To order a replacement, go to the
  Xbox Online Service Center.

Try this out and let us know the results.

An Xbox Wireless Controller purchased in or after June 2015 can take updates wirelessly without connecting with a USB cable. This controller has a small, circular 3.5-mm port on the bottom of the controller (controllers without this port must update via
USB cable).

If you have a stereo headset adapter, plug it into the bottom of your controller so it can also get updates.If you're using a stereo headset adapter, plug in a headset (a headset must be plugged in so the adapter will turn on).Press the Xbox button  to
open the guide, choose System > Settings > Devices & streaming > Accessories, and then select the controller you want to update.Select Device info, select the Firmware version box, and then select Continue.

Things to keep in mind

The auto-detect feature of this update may not work immediately if you plugged your stereo headset adapter into the controller while downloading a system update, or while the console was turned off. To fix this, go to the Home screen and unplug the adapter.
Then, plug the adapter back into the controller.You only need to update your controller one time to use the stereo headset adapter. However, if you plan to use the stereo headset adapter with other Xbox One controllers, you’ll need to follow this process for
each controller. Additionally, check for new updates periodically as Xbox frequently ships new controller features and improvements.

About updating controller, To use the Xbox One Stereo Headset Adapter with your Xbox One Console, you’ll need to update your Xbox One Controller with the latest software to support the Adapter.

So Titanfall controller update is done by over air, no cable, (February update) and Stereo Headset Adapter controller update you need an cable, which comes with the adapter (March update).
