How to define multi-room groups for Airplay 2?
We have Airplay 2-compatible amp/speaker systems in several rooms. I'd like to define groups so that we can stream to multiple rooms in sync at the same time from our iPhones, iPads and MacBooks.
I understand this is possible in Airplay 2, but don't know where to look to set up the multi-room groups, and a web search is only turning up older articles from before Airplay 2. Can anyone help?
