AirPlay 2 not working on any of my devices

@jimbo, what build version of Roon are you using for Roon Server? Are all of these Apple devices installed in the Apple Home app (I’m assuming as you mentioned some are configured as stereo pairs), but want to confirm. Also, do you have an AirPlay password set for these devices?

There are many threads about AirPlay with Roon’s recent addition of AirPlay 2 support. Two of just a few of them are listed below, others can be found by searching the Community:
