Hello!
I use a Asrock Z270 ITX MB with HDMI 2.0 and a Pentium G4600, connected via HDMI to my Denon AVR X3300W.
When I play movie files with HD audio like Dolby TrueHD, DTS HD Master Audio, DTS High Res., Dolby Atmos…, i get no audio to my AVR over HDMI.
Tested with 17.0 and 17.1 under Windows 10 with the lates drivers.
I turned pass through on with the WASAPI Denon AVR device as usual and checked every audio type for pt.
Sync playback to display is turned off.
With this settings non HD DD and DTS audio streams are played fine as expected.
But if i choose a file with HD audio, my AVR gets no/wrong Audio signal (unknown).
The Kodi info screen states pt with the right amount of RAW audio channels, but it seems that the AVR dosen’t recognise the stream.
If I let the file play for a while, there is sometimes audio only just for a second.
When I play the same files with a software player (MPC HC) which use LAV filters (set to bitstream) every HD audio stream including Atmos works fine.
The Windows 10 build in movie app works as well with DTS HD (other HD formats not fully supported).
I tried different Kodi settings and other HDMI cables, but no luck.
