In looking at the signal path for my music, something seems to be missing now and I can’t figure out why. I’ve restarted my core device, the streamer and the iPad I’m not sure what else to try.

MacBook Air (Core)
Lumin D2 (streamer)
McIntosh integrated
Looks fine to me. It authenticates as MQA then you get a full decode. The only other option would be to do the first unfold in Roon (set the device capability to renderer only) and leave the Lumin to do the second stage. It would look different on the signal path but the result would be the same to all intents and purposes.
Your current signal path is correct and is the expected default.
You may experiment with setting MQA Capabilities to “Renderer Only” for Lumin D2 and see if it sounds any different. This will result in an alternate signal path with Roon doing the MQA Core decoding (first unfold) instead of Lumin D2. The MQA Core decoding should be the same with the same intermediate digital output, but there is a difference in where the processing is done.
