This one started with a single user and a very specific problem. He had a Lyrion Music Server setup - content stored on LMS, speakers/players distributed across the house, all controlled from there. Output Routing didn't solve it. DLNA/AirPlay didn't solve it. But making Zenteek speak the Squeezebox protocol properly would have taken weeks.
So I took a different approach.
Zenteek plays, Lyrion distributes.
Zenteek now hosts a continuous HTTP audio stream on your local network - WAV or FLAC, whatever is working for your box. Any HTTP-capable player can consume it. In Lyrion, you add it as a Favourite and it shows up like any other station.
The result is a clean separation. Zenteek handles everything on the audio side - playback, DSP, EQ, Crossfade, Gapless, Loudness, the full chain. Lyrion handles everything on the speaker side. Neither system needs to know much about the other. The stream is the handshake.
It works for anything that can tune into an HTTP audio stream. Lyrion is the obvious case. Old Squeezebox hardware, certain network receivers, even VLC. If the programm can point at a URL and play, it works.
A few caveats worth being upfront about: the stream has no TLS and no authentication. Keep it on your local network. FLAC support is somewhat experimental as older hardware may not handle it cleanly, in which case WAV is the safer option.
Enable it in Settings under Network Stream. Copy the URL - paste it into your player of choice.
Enjoy!
