Kodi 17 RC3 Audio Passthrough won’t work

Hiya,

I’ve recently updated to Kodi 17 RC3 and ran into massive troubles getting audio passthrough to work.

Problem:
Whatever I try, Kodi won’t pass through dts or ac3 audio to the avr. I’ve tried all possible combinations now, but only WASAPI and 5.1 Setup works (which is not an option because I want my avr to do the decoding).

Hardware:
Kodi 17 RC3 running on Zotac ZBox ID-83
Denon AVR 3313
HDMI-Connection

Settings for logs:
Audio Device: WASAPI (AVR)
Channels: 2
Passthrough: enabled
Passthrough device: WASAPI (AVR)
all supported formats enabled

Results: AC3 and dts movies play as 2.0; However, playing dts 5.1 encoded flac files work!

Providing two debugging logs:

Log1: Starting kodi and playing a movie with dts 5.1 sound -> passthrough doesn’t work.

(cannot use pastebin because pvr blows up log!)

Log2: Starting kodi and playing a dts-5.1-encoded flac -> passthrough works.

Hopefully someone will be able to help me!

Thanks a lot in advance,
