I have just purchased some Apple AirPods Pro. 
I can connect them to my Mac and using the Qobuz App play music back directly to the AirPods while the system output is still directed to my iMacs internal speakers.
I was hoping to be able to do the same with the Roon App on the Mac but don’t seem able to select the AirPods in Settings > Audio.
The only way I have found to do it, which isn’t ideal, is to change the Mac’s system audio settings to output to the AirPods and then enable and select System Output in Settings > Audio.
Am I missing something, or is this functionality missing in Roon?
