Hello everyone,
I just build my new home and isntalled stereo passive speakers in the ceiling of 10 rooms.
I would like to be able to my central networking rack and have the following requirements:
– each room can play separate stuff
– rooms might be grouped
– external stereo AMPs per room (RCA input)
Do I have to go with separate RPis for the 10 stereo-zones or could I use less (even 1?) RPi3 with USB soundcard (e.g. 3 7.1 soundcards) to play the different zones separately? Or would one/two/three RPis not be powerful enough to run the system?
As far as I understand it would not be possible to run M2P on e.g. an Intel NUC (for more power) with several soundcards instead right?
Points one and two are ideal for a Squeezebox System with one Pi running the Squeezebox Server. It lets all players be controlled with one interface over the network from any browser or app and also supports synchronous and individual streams.
For the RCA output to your external Amp’s, a DAC HAT with the Raspberry Pi would be the best solution, especially in regards to sound quality.
However, there have been a few people who managed to achieve getting several outputs split from a 7.1 USB DAC. This is not a solution that we officially endorse but it might help you along 😉
