Apologies if this sounds simple minded (it's me not you) I use the most recent OS and firmware - 2.2.0-RC3 + Firmware 12.2.10 - AIR only connects on my Mac if I choose AIR as the Devialet input, otherwise it remains 'grey' and disabled. - in your example you have OPPO as your input. Alternatively, I had a problem recently which was a faulty ethernet cable or switch, by replacing them AIR re-appeared - probably not your problem as you appear also to be WiFi enabled.
