I’m in the process of building a multi-room audio system atm.

Snapserver/snapclients for the streaming audio, 1 audio stream with mpd to be set as 24/7 music, 1 for podcasts, 1 for alerts.

Alerts interrupt both streams to play the alerts. PI 4 for the main audio stack, first speaker, 2nd PI zero w/pirate radio hat/2 5w speakers for the portable speaker that should run most of the day on battery.

PodFetch gets the podcasts, script creates a playlist each day to play the oldest podcasts first. Although kinda surprised PodFetch doesn’t seem to let me do this.

Once it all runs smoothly i’ll put PI Zero W’s/Speakers in the other room and then going to build a 7” esp32 display to allow selecting which speaker plays which stream. Maybe later do something where each stream plays a different genre.
