I’ve gone about as far as I can but the 7.2.4 setup was initially for movies with the Dolby Atmos soundtracks. Dolby Atmos music will be a bonus if/when Roon adds the capability. And that depends on it working with a NUC/Rock to Denon receiver with HDMI. My Denon receiver is the only device I have that has the Atmos decoder and the speaker connections.
I’m not into Dolby Atmos music, but I recently purchased a used Mac Mini to reboot my Nucleus and reconnect Tidal and Qobuz to keep Roon ARC working when away from home for weeks at a time. I just moved the Mac Mini to our family room and connected it by HDMI to my LG TV with HDMI to my Bose 5.1 system. I have free Apple Music (thanks Verizon) and listened to some Dolby Atmos yesterday. Of course, no overhead channels with 5.1.
