[jellyfin] Playing flac encoded files end with error 404

[eematze]

Since the update of mpd to version 0.23.x the playback of flac encoded files from my jellyfin server is broken.
I tracked the problem down to the point where the track url is loaded into the mpd playlist. This is done by the load command (

volumio-plugins-sources/jellyfin/src/lib/controller/play/PlayController.ts

Line 269 in 4dd4acb

return mpdPlugin.sendMpdCommand(`load "${streamUrl}"`, []);

) which should only be used with playlists according to the mpd help. With .mp3 files afterwards the track is loaded by the addid command but not with .flac files.

Before the bump of mpd the code was the same, but mpd 0.21.x seems to report something that helped to also load the .flac file with the addid command.

I removed the load section completely for testing purposes and volumio was able to play .flac files again.
