I think this will do what I want, but I want to run by you guys as I am unsure what plugins I need, I have purchased the premium license, I have a raspberry pi b+ with a behringer uc222 usb audio card as well as currently 2 raspberry pi a+ with hifiberry’s. What I am attempting to do is send audio from a sound board attached to the b+ with the behringer via rca attached to lan on my home network, and then want the audio to come out the 2 raspberry pi a+’s using the hifiberry and connected via wifi to the same home network. I see how to install the squeezebox players and how to add the hifiberry, but what I am unclear on is how to set up the server to use the audio in from the behringer, can anyone point me in the right direction?
