Raspberry Pi + Snapcast + Any speaker with an AUX input

I've got a few Pi's hooked up around the house now to extra speakers, home stereo, and even a .NET snapcast client running on my desktop PC.

That setup plus Music Assistant has been awesome so far. No proprietary hardware or closed source software :)

Snapcast is really good. I use it too. And on a recent Ask HN thread, I saw that someone had implemented it for ESP32 chips, so now I will try that out too.
