No sound on some movies (Atmos) x86

    (Cross post from Kodi forum as suggested by a user there.)

    Hi. I am a happy Kodi user, but migrated lately from Rpi LibreElec to x86 version since I upgraded my speaker setup to 5.1.2 (atmos). I run it from Up Core mini PC

    „...Powered by Intel® Atom™ x5-Z8350 QuadCore 1.44/1.92Ghz 64 bit CPU, UP Core comes with with 2/4GB RAM, 32GB/64GB eMMC 5.0, 2 x USB 2.0, USB 3.0, HDMI, DSI/eDP, 2 x MIPI-CSI supporting 2M Pixel camera and 8M Pixel camera, WiFi 802.11 b/g/n, Bluetooth 4.2 with Ampak AP6214 on board...”

    I have it connected thru HDMI to my Onkyo TX NR656, and to projector. I have enabled passthru sound for each option in Kodi but when I try to play some Dolby Atmos movies I get no sound on my amp. HDMI logo is flashing on amp display and when inspecting the stream in amp menu I get only video, no audio info. I tried it on dolby atmos demo disc I downloaded, and some atmos demos from dolby website. No sound at all. But some other atmos demos seem to play OK with ceiling speakers working. But I get no Atmos logo on amp display (I do not even know if I should get one)

    Kodi Krypton stable

    Can someone help me?
