i am not totally sure about what im saying ,but apple states on mbp 14/16 page that they have :
“Support for spatial audio when playing music or video with Dolby Atmos on built-in speakers”
and it says it has 6 speakers,does this mean you can play real 5.1 files ?
in any case ,even if it isnt truly 5.1,it supports dolby atmos (software one which is able to emulate the multipoint sound )at least ,as it says buil-in speakers
is this implemented and working on infuse ? i cant be sure
