Beebox-S U7100 with Libreelec 8.1.2 no HD sounds

  • Hi there,

    i have an Beebox-S u7100 with 4GB RAM and 60GB SSD and installed Libreelec 8.1.2.

    My Sound System is an Yamaha RX A1050 Receiver with DTS TrueHD and DTS-HD Master Sound (and more) and the Beebox is plugged over HDMI 2.0 with and HighSpeed HDMI cable with 18Gb/s. So the PreRequisited are fully filled but if i setup my Libreelec to Passthrough mode then my sound is very noisy and disharmend.

    If i take a look into the Kodi.log i can´t see nothing what is happen here so i hope somebody as an idea what or how i can fix it.

    I read different forums article and in one they wrote that libreelec has an issue on HDMI 2.0 support, if this right how i can fix it?

    with best regards

    André
