dolby atmos 7.1 channels not working

Hi, anyone, i have my xbox one and i have Kody since a long time ago, i love ir because i can reproduce music in almost any format, but in this actualization in Omega it doesnt seams to work properly the 7.1 channels forced to be upmix stereo in every channel, does a ny one knows why?, and the reproduction of DSD archives seams to block the main program. Any one have the same troble?
thanks
