Plexamp headless couldn’t have arrived at a better time for me. I was just moving back home some months after a catastrophic flood event destroyed, among many other things, my Chromecast Audio and Sonos Connect devices.
I now have Plexamp streaming around the house to multiple Raspberry Pi connected to AV receivers and powered speakers, using snapcast, with an instance each for my partner and me so we can take turns controlling the music.
Thank you to the developers and contributors for making Plexamp what it is.
Thank you to the folk who mentioned snapcast in various threads back in the v1 days.
Apologies to @chrisboll - I hope you didn’t outlay too much on Sonos devices based on my previous advice, it turns out patience was the best option after all!
