I use Android and have a Chromecast dongle attached to the TV. The TV is connected by optical to the NDX2. If I use the Qobuz app on the phone/tablet and chromecast from the app to the TV (via the dongle), the album art and tracklist is displayed on the TV, and the sound comes from the TV via the optical to the NDX2.
So this works but obviously with a bunch of compromises. Though sound is good enough for party type situations.
The only other option I am aware of, and without the compromises, is using Roon, which can use the Chromecast dongle (or a browser built into the TV) to display art.
If there is an alternative in the Apple ecosystem, I would not know
A while ago just as an experiment I installed the Naim app on an Amazon Fire TV stick and it worked surprisingly well. I didn’t test the full functionality of the app but everything I did try worked fine
Following the above, you can play Qobuz on iPhone (maybe also Mac) and AirPlay to the AppletTV.
This should show the art displayed on the TV and play through TV to the Atom.
No playlists or fancy stuff, just art, title, artist, like would be shown on the Arom display if directly AirPlay‘ing to it.
I’m not sure of your use case, but it may do, what you want.
(With couple of drawbacks: quality is reduced to 44/16 at best, including conversion though 48kHz AppleTV output, additional power consumption on playing phone, power consumption of TV, … - for audio quality playing directly Qobuz through Atom will be mich better. But if the screen is important.)
Ah, while playing with my equipment here: ihr be you also need to disable the screen saver on AppleTV. (Which stopped display of artwork.)
PS: it takes a bi, before my AppleTV shows the artwork, likely waiting for normal use of the menu, before switching to artwork from AirPlay.
I’ve tried Apple Music that works with airplay, I can have the album art displayed but as you say it’s a lower quality. I don’t subscribe to Apple Music, I want it all, HiRes and album art on the TV. Eventually it may come, if Naim and Apple get together or Spotify finally presents us with HiRes.
