My Synology DS416Play NAS can output stereo (up to 24/192) via USB when 'USB Speakers' is selected as the output when running DS Audio Station. But what I'd like to know is whether it can output multichannel audio via USB to a device that supports 5.1 audio via 'printer-type' USB input such as an AV Receiver, albeit it'll probably only be a feature in high-end AVRs. Fwiw, I know my NAS can play these files, but seeing as I've only got a stereo DAC connected to the NAS the files are downmixed on the fly to stereo, so I don't know whether it can or will pass 5.1 audio unmolested via USB to a suitable device. Fwiw, my Fire TV running Plex within Kodi can stream these files but it sounds sort of crappy, so multichannel audio via asynchronous USB would be a better option.
