Make sure that new batteries are inserted into the controller. When the batteries have a low charge level, some features of the controller such as audio and rumble are deactivated to optimize the remaining charge.
Make sure that the headset adapter is securely connected to the controller and that the 3.5 mm cable from the stereo headset is securely connected to the headset adapter. You can perform this verification by pressing the voice mute button and checking
that the LED lights up.

the controller. To order a replacement headset, visit the Xbox online Help Center.
