so playing with Audio Hijack, it seems my "Airplay" audio output is *only* present in the interface if I'm currently choosing "Airplay" as my default audio output from the system
So basically with Audio Hijack I can do a "hack" which is:
- set my laptop to play on Airplay
- play some music there
- then if I want to listen to something else on my laptop, I have to create an Audio Hijack pipeline to play some other app on my laptop
Obviously I would prefer the reverse: by default play everything on the laptop, and be able to play a specific app on Airplay... but this doesn't seem to be possible because the "Airplay" device "disappears" from the interface as soon as I stop setting it as the default laptop output
