I’ve been using a Navidrome server with Feishin as a desktop client (though I’m looking for something a bit more feature-rich) and play:Sub as a mobile client with a tailscale link. No idea if this is a dumb way to do this, but it works for me. I don’t really get any buffering unless I’m trying to play a FLAC out in the middle of nowhere.
I switched all my server stuff to my m1 Mac mini because previously I was trying to host everything off my truenas scale NAS with truecharts. Since truecharts isn’t really an option for future truenas updates and I already had an m1 Mac mini I bought secondhand, I figured it’d work pretty well for docker containers, which it does. And it’s a ton more easy for me to troubleshoot than K8s.
