Hi, I have created a simple sonos linux controller. It’s not meant to be player. But it might help you if you just want to skip a song or change the volume.

Any suggestions and feature requests are welcome.

Also I only have 3 rooms and only sonos playbar which seems to be discontinued.
Help with testing on the newer hardware is very welcome.
