DS216 fails to stream DSD music to my network player

[kensklo]

I am a total newbie with NAS so please bear with my trivial question below.

I have recently setup my first ever NAS, a Synology DS216, with the purpose to stream my stored music via an Ethernet cable to my network player which plays both DSD (native as well as DoP) and PCM files. The network player I'm using is a Japanese brand called Sforzato.

First I have checked the Synology website and confirmed that DS216 does indeed support DSD files. I then setup MinimServer with MinimStreamer and directed the server to my music folder. When I tried to play my music through BubbleUPnP, I was only able to play the PCM (AIFF, FLAC, etc.) files. All DSD (DSF and DFF) files were rejected with an error message stating "illegal MIME type". I want to play native DSD, by the way, and not DoP if possible.

On the MinimWatch log I noticed that it stated "Warning: Truncating incorrect value for DATE tag...", which I searched on the web and subsequently corrected the date tag problem, so now no more warning messages are found on the MinimWatch log. Unfortunately the illegal MIME error message continues to appear whenever I try to play my DSD songs, and so up to now I still fail to play my DSD music.

I am not sure whether this is a MinimServer issue or some setup problem with my DS216. Would someone please enlighten me?
