Dolby Atmos on MacOS

[mkt]

Ok, but in which case the Atmos config can be selected in Audio Midi?

Yes (this is with loopback)

7.1.4 is the maximum speaker count available from the Atmos renderer in OSX.

you can get to 9.1.6, as it is defined in coreaudio. It is just the AudioMidi setup utility which is limited.

I have 5.1.4 working at home

This utility opens more options:

I am using BlackHole 16ch on Mac Mini, but audio MIDI allows me to set the output device only as 7.1.4 despite the 16 channels. The Atmos option in the drop-down menu is disabled.
How did you set Amoeba?

I used loopback, I created a virtual 16ch interface, that I connected to my real interface. Loopback is smarter than Blackhole, which is not really developped. Apple Music recognizes loopback as Atmos capable.
You can try loopback for free, see if it works for you.
