I’m new to Symfonium but have used Sonos with BubbleUPnP for a long time where it’s never displayed any Sonos groups, instead I have to make sure that I play to the master speaker (the speaker you click on in the Sonos app to initiate group creation) in order for it to work correctly.
I’ve just tested this in Symfonium with a pair of Play 1’s and if I play to the slave the sound comes from only the one speaker, whereas if I play to the master it comes from both.
