I have a HomeKit scene that plays music to multiple Sonos speakers. I just noticed that for some reason it’s creating multiple groups, each playing the same thing, except one group. As an annoying consequence of this, as they’re playing an Internet radio station, the different groups sometimes get out of sync slightly, resulting in an annoying echo effect as some speakers are very slightly behind the others. If I go into the Sonos app and move all the speakers into a single group this fixed is, but that kinda defeats the purpose of having an automation to play the music.
Is there anyway to control this to get it to just create a single group? My assumption is that this would need to be on the Sonos side of things, as HomeKit just sees the individual AirPlay speakers.
