To confirm what Patrocks has suggested:
I use the (free) Logitech LMS as my central music and radio server. I have a few actual Squeezebox hardware players round the house, but I recently installed the “Xsqueeze” add-on to Kodi on a Raspberry Pi 3. This means:
(a) the Pi still works as a Kodi video client driving my TV, and yet also
(b) the Pi, with the Xsqueeze Kodi add-on runs as an audio client off LMS - which means it can be synchronised with my other Squeezebox players.
Naturally, you don’t NEED any Squeezebox hardware to do this. This solution gives the OP free, synchronised, audio players round the house based on Raspberry Pis and free central software.
Even if the OP has his reasons for not wanting a Logitech solution, this does work, if others are looking for such a system.
Edit: BTW: ALSA is needed for audio playback, and the Xsqueeze Wiki describes how to determine if it’s installed, and how to do so, if it’s not.
