1) Put LMS (https://lyrion.org/) on your home server/a raspberry pi. 2) Get a bunch of raspberry pi zeros with a hifi hat. 3) Put picoreplayer (https://www.picoreplayer.org/) on them. 4) Use the material skin (https://github.com/CDrummond/lms-material) so it doesn't look like 1995. Congrats, you now have your own, fully open source, sonos equivalent for multi-room synced audio. Supports all major streaming platforms as well as a local library.

Another solution that is surprisingly powerful is Logitech Media Server [0], which despite its name is open source and cross-platform. The server can run on any unix-ish machine, and clients can be any number of Raspberry Pis or ESP32s, or custom boxes, or any computer. Multiroom syncing is great. Works for local library and streaming. There is even a modern web interface available [1]. I looked into many of the other solutions in this thread, and LMS suited my needs best.

> improving the front-ends for LMS Completely agree. I'm a big fan of the material plugin [1], in particular when viewed from a tablet-sized viewport. Easy to setup for family members as no apps need to be installed. [1] https://github.com/CDrummond/lms-material

I am still a very happy Squeezebox user. The product is officially dead from Logitech but the ecosystem is alive and well. This proves to me that it was the right choice to buy something backed by open source. Around here you can still find used squeezebox hardware for a reasonable price. If you want fresh hardware then go for Raspberry Pi with a DAC hat. If you want to get started easily today then look at https://www.picoreplayer.org/ If you run Windows then Squeezelite-X is a must-have: https://www.microsoft.com/en-us/p/squeezelite-x/ And if you think the interface looks old - then get the material skin (it is just a checkbox on the add-ons page in LMS) https://github.com/CDrummond/lms-material The "Squeezer" remote works very well for Android. https://play.google.com/store/apps/details?id=uk.org.ngo.squ...

The Logitech Media Server (Slimserver) is still being developed [1] and coupled with Chromecast Audios (through squeeze2cast [2]) or Picoreplayer [3] works as a great multi-room system for me. Spotify integration is available through a third-party plug-in, Spotty [4]. Someone is even developing a great Material design skin for the web interface that is mobile compatible (and works great in a Hermit web app) [5]. Control apps exist for Android and iOS (iPeng [6]).
