Dts And Dolby Digital Xiaomi Box 4k

I just got my new Xiaomi box 4k hdr. The newest box.

I have a problem with the sound.
I only get stereo and dolby digital trough vlc player and xbmc. No dts.

Plex only play stereo.

Everything else tested is only playing stereo.

This is so annoying.

I can'tunderstand how xiaomi could release a new tv box with issues like this without testing it.
Most important thing is picture and sound on a device like this..

I use spdif cable and like I said I am getting dolby digital on some...
