Minimstreamer : transcoding problems on 2 minimserver sessions

[Patatorz]

Hello everybody,

I use minimserver and streamer on a QNAP TS251. In fact I have 2 minimservers that can run on this NAS :
>> 1 minimserver on a virtual machine (Vortexbox)
>> 1 minimserver on the OS of the QNAP itself

My streamer (Belcanto refstream) and my DAC (Totaldac D1 Dual) can play native DSF files.

In my minimstreamer settings i only have "flac:wav" set and nothing concerning DSF, meaning that I should be able to read DSF natively.

But when I use minimserver on the Vortexbox, the DAC is showing a 176kHz signal and when I use the minimserver on the Qnap I can see "DSD" on my DAC.

Parameters in minimwatch are strictly the same....

Any idea how I can play native DSF files on the minimserver installed on the Vortexbox Virtual Machine ?

Thanks for your support.

PS : if you ask why I play minimserver on a vortexbox in a VM environment : strangely is is much more better sound than on minimserver installed on the QNAP itself.
