Thanks for our answer. In the meantime I got a better understanding of how it works although some things aren’t entirely clear.
But if I understand correctly then I only need 1 Rpi per room, I can just install them next to my amplifier since my amp sends audio to speakers, the rpi’s provide input. They can be controlled from the local network using lms or squeezebox server or another Rpi using jivelite.
Within max2play one defines the music library location, the 2 Rpi’s are then configured as clients by squeezelite.
Is it then correct to state that I can use the lms Ios app to play music to the dedicated rpi,say kithen/bathroom Rpi?
