[BUG] Audio passthrough acts different with Portable mode?

Hi there.
I’m sorry, but is it possible that audio pass through modes (AC3/DTS) acts diffently with portable mode (kodi.exe -p) than with “real mode”?

I am having major trouble with all 17.x series with movies that has DTS-HD/True HD audio tracks.

In plain mode I can set WSAPI-Spdif as output and the DTS & AC3 on and the movie that has DTS-HD still plays DTS mode on my Pioneer.
But if I now invoke portable mode, Audio is not DTS, just plain Stereo..

Same settings ofcourse.
With Jarvis (16.x) all works percetly and DTS-HD & TrueHD plays as DTS..
Thank you.

Do I have to submit Debug Log?
