No HD Audio Passthrough on Intel NUC7PJYH2

1st Official Post

    Hey guys,

    Iam aware of the passthrough issues with the 6th NUC generation. Is the 7th generation affected from the same problems?

    I bought the mentioned Intel NUC 7PJYH2 and disabled the HD Audio DSP in bios to get audio working.

    Unfortunately I can't see any HD-Audio passthrough options in the menu!? DTS-HD gets forwarded as 'normal' DTS to my Denon AVR.

    HD-Audio passthrough with my old NUC N2830 works as expected.

    I use the following milhouse-build:

    LibreELEC (Milhouse): devel-20200229234254-#0229-g36ecc2d [Build #0229] 9.80
    kernel: Linux x86 64-bit version 5.5.6


    Anybody aware of the issue and knows some way to fix this?


    Many thanks in advance!

    Best regards

    Alright I figured it out. After disabling the "HD-Audio DSP" in BIOS the sound is working, except the hd audio passthrough.

    After some more troubleshooting I notice that the snd_soc_skl module/driver still gets loaded.

    Code
    htpc:~/.kodi/userdata # lsmod | grep -i snd_soc
snd_soc_skl           139264  0
snd_soc_hdac_hda       24576  1 snd_soc_skl

    After blacklisting the module and rebooting the system the appropriate module does not get loaded anymore and hd audio passthrough works as expected.

    Greetings!

    Thank you for your quick response and the explanation 😊

    Now Iam struggling with playback of Netflix streams with activated hevc profiles. Unfortunately I don't get any output if I switch on hevc profiles. Anyway I will create another thread for this topic. Many thanks again for your support! :)

    Hello. I have the same problem because my NUC with the J5005 processor does not play sound even though I have turned off the HD Audio DSP sound in the bios. Bios is the latest. What am I doing wrong??
