Look at https://www.picoreplayer.org/ using some sort of dac for the raspberry pi. Something like https://www.hifiberry.com/ or https://www.raspberrypi.com/news/iqaudio-is-now-raspberry-pi/ . Easy to install, works pretty flawless and with LMS server can be used as a single full home audio or play zones independently. Not sure if it can do the single speaker type syncing but you can set one left and the other right and sync them to play a single audio source. The only thing I have not done is take an input from a device like a tv as stream source.But with a pi that has bluetooth you can use bluetooth as an input and stream to all other pcp devices in your network. I use raspberry pi 4 1Gig memory with an external poe injector which simplifies powering them and gives consistent network. But 12v input from a power outlet and wifi works well enough in some spots too. It is essentially as close as you can get to plug and play squeezelite as I have found
