Synology/Windows Minimserver different behavior

[stefano_mbp]

Hello Simon,
I’m reporting a issue for a friend
He installed Minimserver 2.1.2 (Starter edition) on a Synology nas DS 220j and use Heos app with a Marantz ND8006.
He has defined a folders structure where under the folder Artist he has several dsf tracks each of them have the album artwork embedded.
Using Heos app no artwork is shown by Heos browsing by [folder view]
Using MConnect Player and browsing the same folder/s artworks are shown.
Then he installed Minimserver on a Windows pc (same 2.1.2 version) defining in contentDir the same Synology share.
In this last scenario Heos can show all artworks, of course artworks are shown by MConnect Player too.
To be noted that with other folders where there are flac tracks instead of dsf everything works fine with Minimserver/Heos running on Synology.
Those symptoms let think that Synology Minimserver version has a different behavior than Windows version (same 2.1.2 release).
Does this different behavior give you some hint?
