Although it does seem to be broken currently
I’m looking at this hifiberryOS as a possible replacement for volumio with a snapcast server for whole house sync’d audio (2). Looks pretty full-featured but I haven’t tried it out yet. Maybe others know of good music software for the pi or have experience with this?
But given that they have other direct-playing applications it is a strange omission.
Which means - you're expected to plug it directly into (or build into) a speaker.
DLNA is pretty much the only open standard in existence to play music stored on one device on a second device, controlled by a third device.
DLNA is few notches below NFS in complexity. It has autodiscovery in the local network and optimized for library organization, control and streaming.
Using NFS instead of DLNA is much like what Russians call "sunset by hand".
