Wiim Mimi fails to play files from MinimServer

[simbun]

Yes MinimServer does send 'DLNA.ORG_PN=MP3' for mp3's so maybe it's not that that's causing the problem.

Code:

AssetUPnP
<res duration="0:03:22.000" size="8114100" bitrate="40010" bitsPerSample="16" sampleFrequency="44100" nrAudioChannels="2" protocolInfo="http-get:*:audio/mpeg:DLNA.ORG_PN=MP3;DLNA.ORG_OP=01;DLNA.ORG_CI=0;DLNA.ORG_FLAGS=037000000000000​00000000000000000">http://192.168.20.12:26125/content/c2/b16/f44100/d7567312460699755660-coDCB071445BC34CFF.mp3</res>
MinimServer
<res duration="0:03:22.762" size="8114100" bitrate="40000"                    sampleFrequency="44100" nrAudioChannels="2" protocolInfo="http-get:*:audio/mpeg:DLNA.ORG_PN=MP3;DLNA.ORG_OP=01;DLNA.ORG_FLAGS=01700000000000000000000000000​000">http://192.168.20.12:9790/minimserver/*/MUSIC_TEST/John,*20Elton/2021*20-*20The*20Lockdown*20Sessions/CD01/01.01.mp3</res>

Looking at the control point metadata for AssetUPnP (see image attached) it seems to offer multiple streams, I have no idea how to control that (if I even can), but maybe Asset always streams, which does work in MinimServer.

In the DIDL, Asset flags the mp3 streams and the WAV stream with 'DLNA.ORG_CI=0' and the L16 as 'DLNA.ORG_CI=1'. Given the WAV stream can't be the native file, that flag must be more nuanced than just native file vs stream I guess.

EDIT: BubbleUPnP does indicate that a FLAC/MP3 is being played from Asset.
