Jellyfin Music Album Playback gives error: "Client isn't compatible"
=======================================================================
This is due to permission issues that jellyfin cant read that file on your/my NAS folders.
To fix this run this command (replace the folder with the correct one):
sudo chmod -R 777 /opt/RD/*

Restart jellyfin and it should now be able to read the music file and playback it.
