Xbox Series X and ButtKicker Gamer 2

I’ve just traded my XBox One X on a new XBox Series X and I’ve just bought a new ButtKicker Gamer 2. The trouble is the new XBox doesn’t appear to have a headphone jack, and the ButtKicker wasn’t supplied with a USB connector. I’m using both USB 3.0 slots anyway for a Rig wireless headset and Logitech G290 Wheel/Pedal kit. Does anyone know how to connect the BK and XBox console (i.e. do I need another cable/splitter/etc) or am I missing something else?

Did you ever figure it out?

Try to get audio from your TV instead directly from Xbox.
