Can´t get DTS HD on my AVR

Hi there,

I just update my Raspberry Pi 2 with LibreElec e kodi Jarvis 16.1.
I´ve been trying to set the sound settings for have DTS HD in my system but I can´t get it right because the sound reverts to simple DTS … I´ve been trying everything i found on the internet with no sucess …

The raspberry Pi 2 is connected by HDMI to a AVR Onkyo SR607. I´ve been trying to use a mkv 1080p with DTS HD and a BluRay rip with DTS HD …

Can anyone teach me how to do it? With a tutorial for example …

Thanks a lot
