In Android 7.0 DTS passthrough was working at least with Sony's Video app. Now all I get in my AVR from it and also Plex is no audio signal at all. What happened, instead of fixing it they removed DTS passthrough definitively?

UPDATE: Actually it is much worse than that. I tried few videos with HiRes audio (Dolby True HD and DTS HD MA) and I get no audio from my AVR. If I select the speakers the videos with TrueHD have the audio heavily stuttering. DTS doesn't play at all.
