One of my DACs is a Lumin X1. Lumin has a web app for configuring their units and for playing music through the app. Prior to AMSv3.1, K50 showed in Music Library for the Lumin App. I had not tried using the App till today and ran into issue of the K50 not showing online to be able to use. I tried restarting the K50 and deleting the Lumin App and downloading again without getting that library to work. I posted question on Lumin forum at AudioShark wondering if this was similar to needing to deauthorize prior Core in Roon and reloading. I then mused that this may be MinimServer related.
I had Roon selected as server in the K50 and changed to MinimServer. Lumin App on my Desktop M1 then detects MinimServer (antipodes) in Music Library and can play via the Lumin App. K50 no longer shows as Music Library option. If I activate Roon as the Server only, MinimServer shows as Offline. I do find I can activate both MinimServer and Roon Server in Antipodes Server Dashboard and Lumin shows MinimServer (antipodes) as accessible. This is different than before Antipodes software push changes, but it works. If I leave Roon Ready On in the App, I can switch to playing Roon from the Roon web app or select and play from Lumin App. If I shutoff Roon Ready in the Lumin App, my X1 does not show as an Audio Zone in Roon.
I want to also pass my regard for Peter Lie of Lumin. He answered on that forum in less than an hour while I was posting the paragraph above this one on MinimServer. His answer in that forum was "The functionality you need on Antipodes is known as MinimServer. Please have it enabled or reinstalled.
I did not realize we could activate more than one server at a time, but that has solved my issue with Lumin App.
