Our old computer system (iMac G5 2014) was hosting our music library which was running two Sonos Play 5 (get 1) speakers without issues. Each speaker had a unique name, and I was able (via the controller) to turn each speaker on and off individually.
That computer died a few months ago. I went to hook up this same system to a different mac (Mac Mini 2017 vintage), and after a few tries got the system working, but with only one of the two speakers. When I open the controller interface (I updated the software upon moving the system to the new computer), the option of adding/selecting each individual speaker no longer exists. Instead, the only addressable option is a group name I had given the two speakers.
So, how do I reconnect the second speaker into the system?
