I have discovered volumio but there’s not too much information about it.
I’m looking for a replacement of my Synology NAS DS Audio program to stream audio with AIRPLAY to my Zeppelin Air, controlled with my ipad.
Is volumio able to stream music to AIRPLAY speakers?
Thankyou
Gus
I think airplay output to speakers is actually not possible.
Only Airplay input with connection of volumio as streaming server.
I have succesfully installed a forked-daapd daemon, working on standalone raspbian stretch with Zeppelin Air wireless connected 
On QNAP NAS Music Station app I can see Zeppelin as Network player, but no sound is going out 
If a part from this “iTunes” server can be implemented in Volumio, then the functionality would be present.
But it is only my wish and suggestion to volumio develpers
