I cannot play DSD files

[Aldo]

I have a Synology 918+ NAS server connected to my router which is connected with an Ethernet cable to a Weiss 501 streamer-DAC via UPnP. I have the latest version of Minimserver and Minimstreamer installed on the NAS.

I have found this website page

https://designwsound.com/dwsblog/2017/09...-dlna-dsd/

which explains how to set up Minimserver to play DSD files with the 501. (I think this implies that you have to transcode to PCM and that you don’t reproduce DSD natively: just a question, but of course this is not the main problem).
Now, looking at all the pages of the web interface of Minimserver and streamer on the page I linked above, I cannot find any of the actual windows shown in here (e.g. Packages and the transcode option).
I use mconnect HD as app driving the streamer from an iPad: if I use mconnect HD to play DSD files via a miniDSP Studio from
Synology/Minimserver, they play fine (so they are read ok by the miniDSP, which then however always, by defaults converts them to PCM for final reproduction on the Weiss 501, so the Weiss does not actually play the DSD files themselves)

My questions are:

1. Is in your opinion the problem within Minimserver, have I not managed to set I up ? Or is the problem somewhere else?
2. If the website is correct, any tips on how to make the changes it advises ?
Many thanks
