Simple way to access the Audio Midi Setup


I’ve read on other forums that it seems to be possible to tweak the “Audio/MIDI setup utility”. 

As far as I have understood, this would allow the AppleTV to play 24/96 files in their native resolution instead of being downsampled to 16/44.1khz. 

Do you think you can get on eye on this feature which is the only one that I am missing on my AppleTV ?
