  • NUC7i3BNK Bitstream Lossless Audio

    Quote from Klojum

    Call me stupid, but why would you limit your devices when they are probably capable of doing full colors? Limiting the black colors will give you a washed up greyish layer over your display. I would disable the limitation and always go for full colors, on the htpc as well as the TV.

    You may have to up the brightness/contrast on your TV, but in the end the colors come out better.

    I'd really prefer not to derail my bug report with this topic, but since you insist and you're a moderator to boot: you're stupid. :D

    I don't disagree that the answer is not intuitive, but it is nevertheless the answer. I assure you the picture on my reasonably-calibrated Kuro is far from "washed up" and "greyish", in fact a small but dedicated choir of angels sings a triumphal verse each time I power it on, which you'd think would become tiresome but so far has not. If you'd like to continue having this particular fight, send me a DM or open a different thread called "elfurbe is a black-level heretic and must be destroyed" and I'll fight with you there to the best of my ability, but I'm more concerned about my audio problem in this one, if you please.

    Cheers!

    I upgraded my NUC from a Haswell (NUC5) to the new Kaby Lake (NUC7), mostly to get hardware 10bit HEVC at some point in the future. I restored my backup from the NUC5 to the NUC7 and validated all my settings. Unfortunately, I'm no longer able to bitstream lossless audio. Standard DD and DTS work fine, but TrueHD and DTS-HD generate no sound at all. My receiver acts as if no sound is being sent. If I disable the lossless options in settings, TrueHD seems to output as LPCM and DTS-HD downgrades to core, as expected.

    The only oddity I see that's obvious is that X seems to think it's on DP1 rather than HDMI1, but it looks like it considers them clones so maybe that's normal here. Also my xrandr output shows an incorrect "Broadcast RGB" setting, it should be forced to "Full" by autostart.sh. This was a previous Kodi best-practice for proper black levels (TV set to limited, X output set to full, Kodi set to limited), but perhaps 17+newer GPU has created some synergy here that I'm unaware of and "Video 16:235 pass-through" is expected now. I only mention it in case it's further indicative of some problem with the output device, the audio problem is the only thing I'm intending to report here.

    System Details:

    • NUC7i3BNK (i3-7100U, Intel HD Graphics 620)
    • Using the HDMI output
    • LibreELEC 7.95.2

    Let me know if there's anything else I can provide that would be helpful.

    Thanks!
