Code:

<DIDL-Lite xmlns="urn:schemas-upnp-org:metadata-1-0/DIDL-Lite/" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:upnp="urn:schemas-upnp-org:metadata-1-0/upnp/" xmlns:dlna="urn:schemas-dlna-org:metadata-1-0/"><item id="0$folder$f1423$*i44" parentID="0$folder$f1423" restricted="1"><dc:title>2L-038_stereo_01_01.dff</dc:title><res duration="0:09:14.893" size="391533026" bitsPerSample="1" bitrate="705600" sampleFrequency="2822400" nrAudioChannels="2" protocolInfo="http-get:*:audio/x-dff:DLNA.ORG_OP=01;DLNA.ORG_FLAGS=01700000000000000000000000000000">http://192.168.0.33:9790/minimserver/*/Music/audio*20formats/2L-038_stereo_01_01.dff</res><upnp:class>object.item.audioItem.musicTrack</upnp:class></item></DIDL-Lite>

This is intended. Unlike PCM audio, DSD audio is a sequence of 1-bit samples.
