Issue description

Hey having trouble playing anything over upnp that is .dsf files. I have uploaded logs under this user. Claude offers this help:

What’s happening:

  1. Symfonium reads the Denon’s protocol-info (it correctly sees audio/dsd, audio/dsf, audio/dff) and builds a Plex profile containing container=dsf & audioCodec=dsd.
  2. Plex identifies your DSF stream as codec dsd_lsbf_planar, not dsd. No match, so it refuses: “No direct play music profile exists for protocol http, with container dsf using codec dsd_lsbf_planar.”
  3. Plex falls back to transcoding, and its decision comes back as FLAC — but Symfonium hands the Denon a /transcode/universal/start.mp3 URL with audio/mpeg in the DIDL metadata.
  4. The Denon accepts the play command (“Play success”), then reports STOPPED ~1.8 s later. Position never advances past 0 on either DSF track.
