You cannot Airplay to a (named) group directly, but there's two possibilities to Airplay to more than one speaker:
- Airplay to one speaker and add other to the speker, forming a group; or
- select all speakers in your Aiplay list to play to - they willl play in sync.
Method 1 leaves grouping to Sonos, while method 2 leaves it to your Apple device. In my experience method 1 leads to more stable group. Advantage of method 1 is also that you can group non-Airplay Sonos devices with the Aiplay-capable speaker.
Thanks for this - very helpful
Option one does sound best. I will see if I can set it up.
Thanks again for your reply.
