This USB stick will enable you to connect an Xbox One gamepad to your PC rig without an extra USB cable. You’ll just need to plug the adapter into a USB 2.0 or 3.0 port on your system.

They do, but you only get audio out of the built-in headphone jack on PC if you connect with either USB or the Xbox adapter. All the gamepad buttons work with Bluetooth, but not audio-out.

Beyond the Xbox Wireless Adapter, Surface Studio and Surface Studio 2, as well as well as Surface Book 2 and 3, include built-in compatibility with Xbox Wireless, no external devices needed.

So I had the Xbox Wireless Adapter for Windows installed where the USB Composite Device should have been. Without the composite device, you never get the audio device with it.
