Hi @brian, @danny - unfortunately 1.0 release 9 isn’t much better for AirPlay. Playing to a Bowers & Wilkins Z2 speaker over ethernet, drops out every few minutes (although UI shows track continuing to play). Sometimes when I stop the track and start it again it comes back, sometimes not. And sometimes it comes back at 100% volume rather than the previous volume set on the speaker.
Update: just had it stop playing again, this time to a group of an Apple TV2 and an Airport Express, all connected over wired ethernet, and all local content (not TIDAL). As far as the UI is concerned, it is still playing to the group.
As I said before, I really want to love this product but it feels like it just isn’t quite finished yet 
The one thing this software must be able to do is be absolutely rock-solid at audio playback - everything else is secondary. So far, I’ve never been able to use Roon for more than a few minutes without it falling over in some way. And I’ve tried 3 different Macs as the server.
