I have a strange Problem with my Setup

I use the Q10pro with HDMI Passthrough to my Pioneer VSX 1131 (new 2016 Modell with Full HDMI 2.0, HDR, BT 2020 etc,)
ANY HD Audio Bitstream Passthrough works from Q10 pro like Dolby Atmos, DD+, TrueHD and DTS HD MA but NOT DTS High Resolution Audio
DTS MA works, but not HRA, any other Player like Popcornhour works with DTS HRA, but the Q10 PRo outputs only DTS Core from HRA here
tried everything , dont know whats up here... very strange
And i had another Problem with Audio Drop Outs!
This Problem was fully solved with the Lindy HDMI Adapter to block HDM CEC (i had Problems with HDMI CEC caused by Q10pro like blocked ARC etc)
