From a review of the BDT700 in What Hi-Fi:
File compatibility for the DMP-BDT700 is respectable: MP3, WAV, WMA, AAC, Apple Lossless, MKV, MP4, Xvid and JPEG files, including high-res FLAC files (24-bit/192kHz in stereo; 24-bit/96kHz in 5.1 channel).
With DLNA compatibility on board, you can stream media stored on any laptop, smartphone, tablet or NAS device, provided they’re all plugged into the same network as the Blu-ray player.
Audirvana operates as an ad hoc UPnP server and control point. Whether this qualifies as what the user manual refers to as a Digital Media Controller or compatible software, I don’t know.
The vague-ness of support for network streaming of multichannel digital-audio in the majority of players/renderers, seems not worth the hassle… It is a niche demographic of users… I have several 5.1 multichannel DSD files that I will decimate to PCM, but it just doesn’t seem worthwhile at this point, and especially for me, where I would use the Waves Audio Abbey Road Studio 3 surround 5.1 virtualization plug-in for headphone playback at 96kHz… Just not motivated enough to test the viability of using Abbey Road Studio 3 surround virtualization in Audirvāna… It may work… if @Antoine knows it will work, I may expend the energy to give it a try… 
I need it after you made the update 
The problem is the players and DACs are from different eras. Folks using these receivers/DACs certainly can’t be blamed for hoping to make them work, since multichannel DACs designed and built these days can run into expense.
I haven’t heard a present day multichannel rig myself, but folks who have seem very happy with them and the content that’s becoming available. In particular a lot of that content doesn’t suffer from the “loudness wars” that afflicted many of the two channel versions.
The demographic of multichannel music aficionados is just not large enough at this stage… I am one… however, I still use SACD and DVD-A.
Is there an Origin equivalent? UPnP multichannel still not working from AO for me…
We will need to update it. Do you have access Audirvāna Studio on your account or not at all?
No, I use Origin. I look forward to the update!
… because it works with bubbleUPNP.
Bubble UPnP is not the subsystem used in your player… it is running on a different platform as a renderer/endpoint…
Ah. I wonder what BubbleUPnP is sending that Audirvana is not?
Bubble UPnP sends the 5.1 flacs from the network drive to the DMP BDT 700 without any processing. The DMP BDT 700 itsself can play 5.1 flac from network sources. Both solutions do not include gapless play. This is what I hope could be possible with audirvana.
It is apparent that the DMP BDT700 is not implementing UPnP multi-channel protocols in this context… It is DLNA-centric… BubbleUPnP supports DLNA devices…
BubbleUPnP Server provides:
- Secure and bandwidth friendly Internet access to your home UPnP/DLNA Media Servers
- OpenHome compatibility to your UPnP/DLNA Media Renderers
- Optimized transcoding to Chromecast for playing non natively supported formats
- Ability to make your Chromecast an UPnP/DLNA or OpenHome renderer for interoperability with UPnP/DLNA and OpenHome control software
- Ability to fix some issues in UPnP/DLNA Media Servers by creating proxies
It can run on any machine of your local network where Java is available.
Flac (2.0 and 5.1), which the DMT BDT700 generally supports, is not part of the DLNA certification - so what you call “apparent” seems not to be true.
BubbleUPnP may be transcoding as a proxy server…
From the page Agoldnear cited, these seem to me to be potential candidates for what is going on:
BubbleUPnP Server provides a collection of services working on top many of your UPnP/DLNA renderers, media servers and Chromecast devices:
…
- create OpenHome Renderers from any UPnP AV or Chromecast renderer (provides on-device playlist, multiple Control Point access to the same renderer)
…- fix issues of UPnP/DLNA Media Servers (discovery issues, broken data, add some audio DLNA compliance) by creating a proxy Media Server
I understand the manual doesn’t speak about OpenHome, so that may be less likely than the statement about fixing DLNA compliance issues. I included it because various audio devices use the OpenHome standard, while Audirvana uses the UPnP AV standard.
