Is it possible (theoretically, not saying it exists today) to have a single raspberry pi that both accepts a stream (from Roon, from Spotify Connect, maybe someday from Tidal Connect) that outputs not just USB/SPDIF but also contains a DAC and which can output analog audio via RCA? Or do you fundamentally need two hats (one SPDIF, one DAC), and so you need two raspberry pi’s?
I’m hoping to create something that is functionally the equivalent of a Sonos ZP80/Connect - I stream to it, and it outputs analog audio, which ideally I can volume control remotely. I realize I can obviously do it with two units; a RopieeeXL plus a khadas tone board feels like a decent solution for my use case. But I’d ideally like to keep cost down and complexity - so a single box solution would be better.
Let me know if this is such an edger case that it’s not worth even discussion, or if it’s trivial easy. I’m guessing it’s neither of those
