Description Of Issue
When grouping these three “Airplay” devices in Roon, the Apple TV plays out of sync relative to the two Sonos speakers. The sound is immediately out of sync and remains out of sync even if I pause and restart the audio.
There is no option to adjust a “Zone Grouping Delay” or “Clock Master Priority” in the settings for the Apple TV nor the Sonos speakers.
When grouping just the two Sonos speakers together, they remain in sync.
Is there any way to get Airplay devices to play in sync via Roon?
