I would like to stream DSD64, 128 and 256 files from my Synology NAS via a Samsung S4 to a Chord Mojo, which is capable of playing these file types. My setup is as follows:
Synology DS1815+
MinimServer 0.8.4 with MinimStreamer - no transcoding enabled
Samsung S4
UAPP latest version, DSD over PDM checked
OTG cable
Chord Mojo
Playing PCM files all the way to 24bit/384kHz works fine.
DSD64 files play back in good quality, but are reported by the Mojo as 176.4kHz
DSD128 files play back in good quality, but are reported by the Mojo as 352.8kHz
DSD256 files play back in good quality, but are reported by the Mojo as 705.6kHz
As the Chord Mojo only reports samplerates with a color of the LED and I was not too sure about the bitrate it reported (it definitely did not report native DSD), I connected the S4 to a Weiss DAC 202+ (which is capable of DoP on its USB input) and it reports the signal samplerate in clear text. It also reported 176.4 etc. kHz for the DSF files, not DSD
I have tried all possible combinations. Transcoding to DoP on Minimserver on the NAS, turning DoP on and off on UAPP, but I always get PCM on the DAC. Where could I be going off course?
Thanks a lot for any help.
UPDATE: I have now copied three DSD files (DSD128 and 256) to the microSD card in the S4 and they play flawlessly. Both UAPP and the Mojo report the files as DSD.
Could it be that streaming DSD works from a local microSD card, but not from a DLNA server?
