Airplay not working with Devialet, have to use Airfoil to have flawless airplay!

Music Airplay support is badly broken. I have two Devialet speaker, a Phantom I and a II. It is a nightmare to have Music to properly detect the airplay devices. The sole way I found was to reboot the Phantom every time and then in the few minutes after the reboot Music is able to find them and play. To be noted that with Music on iOS I do not have this issue, so its really specific to the OS X (Big Sur and Monterey) airplay stack.

Now to be sure, I tried with Airfoil - from rogue amoeba - and bingo...works anytime. Just selecting Music as the source and it all streams nicely via Airplay on the Phantom.

Honestly Apple you do have a significant QA and Engineering issue going on. The DNS issue which caused me to reboot once or twice a day my Macbook because it was running out of sockets, and this defective Airplay stack - you guys designed the protocol!
