I now have two boards, and 1 raspberry Pi.
I used toslink-connectors to get the signal in and out of the speakers, and used a microsd extension to be able to modify the software of the Pi.
But... what now? How do I get the one speaker to act as master, and send one channel through to the other speaker?
I can't install SigmaStudio on my pc, something with permissions, I think.
Do I really need this, or is there a another way to get a profile for RL6000 stereo setup?
