I posted following help in auddiphile style forum,
I do have question on Roon aspect of what i’m trying to accomplish, whether there is any point of going further.
So, assuming i can get the SonoreUPnP Bridge to detect my renderer (in this case Astell & Kern AK380, which as a comparison i’ve tried BubbleUPnP on Android and it detects and playback to it fine, few test tracks, 24bit/352.8Khz, native DSD256).
My understanding is that such DLNA/UPnP bridge devices/apps that work with Roon presents to Roon as a Squeezebox device.
If the bridging did work between the UPnP/DLNA renderer and Roon, then from Roon point of view, is there Squeezebox device setting that allows Roon to play (natively) DSD64/128/256 and up to 24 bit/352.8 Khz on the renderer (in this case Astell & Kern AK380)?
Or, is there limitation with Roon support for Squeezebox devices that does not support native DSD’s, and only up to certain PCM?
I wasn’t sure if Roon can support renderer that can be treated as pass-through, no conversions needed since AK380 shouldn’t need any conversions in front.
From the BubbleUPnP screen for the renderer, shows following,
And in BubbleUPnP setting for the renderer, i have turned off all conversions, and check for mime type,
