Hello everyone, My name is Paolo and I’m an enthusiast with non-engineer-level knowledge. I have a CD transport with a Toslink output, and I’d like to create a simple DSP using a Raspberry Pi and an input board like the HiFiBerry DAC+ DSP or an IanCanada board. I want to connect the Raspberry Pi to an external DAC (via USB or coaxial). I’ve tried using MoodeAudio and CamillaDSP with the HiFiBerry DAC+ DSP on the Raspberry Pi, but I can’t get the CD transport to be recognized via SPDIF. So here I am, trying to understand more about it.
