    I currently have a Serviio server setup on my PC, which feeds DSD (and PCM) files to my Yamaha RX-A660. 2ch DSF's are a breeze to listen to.

    I recently encountered an iso file that has both stereo and Multichannel tracks. I used SACD_extract to extract the stereo DSF's in one directory and the Multichannel DSF's in another.

    The stereo files play over DLNA. In the signal info screen, the info shows up properly as 2.0, DSD64.

    However, the Multichannel files refuse to play at all. The receiver sees the file on the server, but I suspect, cannot decode them.

    How do people on this forum listen to digital Multichannel DSD files through their receiver?

    Serviio can't do multichannel DSF over DLNA. Do you have the option to convert to PCM? That should work.

    Alternatively convert them to 5.1 flac with something like foobar2000.

    You just killed my dream.

    But thanks for that. Do you know of any other DLNA servers that supports multichannel DSD?

    Also, nvm. My receiver doesn't support multichannel decoding via the onboard DAC for any type of digital file.

    AV receiver cannot play multichannel DSD if sourced using their networking capabilities or if sourced via their USB inputs. The only input multichannel DSD can can be accessed via is via a receiver's HDMI inputs. DSD and DSF via a receiver's networking abilities and USB inputs is restricted to 2 channel stereo. The same goes for multichannel FLAC and or any other multichannel audio format. It is stereo only and a maximum of 2 channels if wanting to access audio via any AV receiver networking capabilities.

    The solution is to access the files using an external media player and use that player to play the files. The external media player would then need to be connected to the AV receiver via HDMI in order to convey the resulting multichannel DSD or PCM to the receiver.

    Denon's and Onkyo's seem to do it?

    What makes the digital data in USB different than the digital data in HDMI? Do they not get processed through the same DAC?

    Also, spec sheet on the Denon's AVR-X7200W claim multi channel support in the file formats, but does not specify transport.

    No AV receiver facilitates playing multichannel audio accessed via either their networking abilities or via their USB inputs. THese two interfaces are restricted to stereo audio. This includes the Denon AVRX7200.

    Do you know the reason why?

    Not really. I can only guess that it has to do with the signal paths. The USB inputs usually relies upon the same board used for a receiver's networking hence why both are subject to the same restrictions. This also suggests that the audio accessed in conjunction with that board is subject to a different decoder than that associated with the receivers other digital inputs? The DAC will be the same DAC, but the signal path to that DAC will differ for the networking board when compared to the HDMI board for example. I'm quessing the signal paths are only stereo in nature so audio is therefore restricted to 2 channels?

    Anyway, for whatever reason, AV receiver do not handle and cannot play multichannel audio accessed via their networking abilities.

    Also, I did make a mistake.

    The spec sheet for the Denon has the multichannel DSD only in the HDMI portion of the manual. In the USB / NAS section, the Denon can do DSD128, but makes no mention of multichannel.

    In answer to your original question OP, I play m/c flac/pcm files via my NAS>Mede8er>Anthem. Works well and you'd never notice the difference.

    What's the transport? USB? DLNA? HDMI?

    The files are being conveyed to the Mede8er media player over a network from the NAS. The media player is playing the files and the signal is then being conveyed to the AV receiver via HDMI.

    By the way, a transport is the device being used to play the content as opposed to the interconnections and protocols employed between devices to convey signals.

    I see.

    I was hoping for a straight NAS to receiver solution without having to go through an intermediate player and HDMI.

    What about devices you currently have connected to the receiver via HDMI. Do any of these have inbuilt DLNA networking and the ability to play the files in question? Some Blu-ray players include such abilities.

    I have none.

    Just a STB and onboard Smart TV Apps.

    My receiver is essentially my Renderer.
