I am streaming Tidal and my CD's through Roon on a Mac Mini connected to my Classe SSP-800.
My issue is trying to listen to the same material at the same time in different zones.  My second zone is
a B&W A-7, so it runs on Airplay.  How can I sync both of these zones to run together?  Do other wifi
speakers such as Bluesound devices sync with Roon?  My whole point is to get better sound than Sonos.
BTW the streaming Tidal sounds amazing.  Mac Mini is hardwired to internet and Roon remotes run well
on laptop and iPhone.
Here's a link to the Roon User Guide:

Here's a key point:

"Zones that use the same streaming technology can be grouped together."

Hope this helps.

Thank you.  I have seen this Roon info, but the GroupZones is not available with my two zones (one is system output - HDMI from Mac mini
to Preamp) (and the other is Airplay).  I just I don't understand as I am not 'streaming' from my Mac Mini at all, why I can NOT add the Airplay speaker to a group.  I want to add other streaming speakers- maybe Bluesound Vault...will these group with my main system output aka Mac Mini?
Airplay devices will only group with other Airplay. Your Mac mini is not streaming with Airplay. My MacBook Pro won’t group with my Apple TV devices either. But it will group with all my other networked devices i.e. all the other DACs I have on my network. So I think your Bluesound will work with the Mac mini but not with the Airplay devices. Also--post your inquiry on the RoonLabs community forum, they are very quick with helpful responses there.
It's crazy because you could do this with iTunes 10 years ago.  Nothing has ever worked more simply and logically than iTunes with the remote app.  Play to any zone you want at any time at any volume.  What's so complicated about this.  
The difference is iTunes requires apple/approved hardware in each zone. What he is doing with Roon is trying to mix airplay and other protocols in a single group.
