Airplay not working on MacOs / M1 Mac mini / ATV 4K
I have 3 x HomePod mini, and 1 Sonos beam (airplay 2 enabled).
When I airplay music from iPhone, it works seamlessly, I can each choose which devices to use, and volume, HomePod can always use Siri to control all the devices.
on the ATV, airplay seems to also work, BUT only the Sonos which is connected to the ATV sound is in sync, the HomePods in other rooms have a second or 2 delays
Trying to airplay music from iTunes or Podcast from my M1 Mac mini (on latest version macOS Monterey), only sometimes it works. Especially if I use computer first then switch to using the phone to airplay, then the MacOS can never take it back. (the phone seems to be always ok to over the airplay streaming from the computer just fine).
Mac mini, macOS 12.0
