It should work with the above config. 
Are they in pairing mode?
To place your AirPods in pairing mode:
- Place both your AirPods in the charging case.
- Open the lid on the case. You’ll see the light come on, indicating the charging status.
- Press and hold the circular button on the back of your AirPods case. The light inside the case will begin to blink white. This indicates that your AirPods are in pairing mode.
The AirPods Pro will remain in pairing mode until the charging case’s lid is closed.
You can now open the Bluetooth menu and find the “AirPods Pro” listing, and connect to the headphones.
If it doesn’t work then i’m all out of ideas.
