  • Intel Alder Lake 2160p @ 23.976 Hz passthrough HD Audio dropouts (i7-1270p/N100)

    smp now i have LE12 too, but the same problem just PCM stereo

    all my images for testing are here https://sky42.libreelec.tv/testing/adl/
    my LE12 builds are the 11.80.4 ones

    lets see if i can learn how to configure pipewire
    any help for pipewire config is very welcome

    the build config i used is
    --- new device with options like this for gbm and x11 ----
    # PipeWire backend device
    PULSEAUDIO_SUPPORT="no"
    PIPEWIRE_SUPPORT="yes"
    KODI_ALSA_SUPPORT="no"
    KODI_PULSEAUDIO_SUPPORT="no"
    KODI_PIPEWIRE_SUPPORT="yes"
    ALSA_SUPPORT="no"

    # the rest is copied from gbm

  • Intel Alder Lake 2160p @ 23.976 Hz passthrough HD Audio dropouts (i7-1270p/N100)

    audio dropouts with screen resolution 2160p @ 23,976 Hz if the Audio is HD (for 9 out of 10 BD/4k remux i tested)

    Use the workaround from post #46

    affected devices tested
    - ASUS PN42
    - Intel NUC12WSKv7
    - MiniX Z100-0db

    not affected devices as counter tests
    - RPi4
    - Asrock B360/ITX-ac with Intel i3-8100 HDMI 1.4
    - Intel NUC8i7BEH

    Edit: workaround is here RE: Intel Alder Lake 2160p @ 23.976 Hz passthrough HD Audio dropouts (i7-1270p/N100)

    setup used
    - HDMI connections only
    - no ARC
    - no CEC
    - LE device -> Denon X6700H -> LG 55E6D
    - as of today a extra new clean installed USB disk for testing with local data to play


    Started here RE: Time to upgrade my NUC. What's hot today?

    my ASUS PN42 has audio dropout with screen resolution 2160p @ 23,976 Hz if the Audio is HD (for 9 out of 10 BD/4k remux i tested).
    PN42 tests and counter tests
    - if not extra stated all in passthrough with only HDMI PN42 -> Denon -> LG TV (no ARC, no CEC)
    - build LE11 and LE12 with the latest updates today for that
    - nearly all DTS-HD, TrueHD have dropout when played with screen resolution 2160p @ 23,976 Hz
    - NUC8i7BEH does play all content fine 1080p/2160p with and without HDR (for LE11 HDR with my Generic-BT2020)
    - NUC8i7BEH has a LSPcon MC2800 HW: 2.2 SW: 1.78 (from /sys/kernel/debug/dri/0/i915_display_info)
    -my LSPcon MC2900 und MC2907 do not work with HD audio on the PN42
    - source resolution does not matter if you play with screen resolution 2160p @ 23,976 Hz and it has HD audio it will have dropouts
    - LE12 makes no difference
    - Generic legacy makes no difference
    - 4k HDR source material played in screen resolution 1080p @ 23,976 Hz has NO audio dropouts and HDR works too
    - disable passthrough and do multichennel PCM works better but every couple of minutes i have a dropout
    - mainly tested by switching between NUC8, PN42 and RPi4 and settings changes
    - for test i did see parts of Alita - Battle Angel (2019) EAN 4010232073624 playlist 00800
    - for test i did see The Fast and the Furious (2001) EAN 5050582731248
    - content from NFS locally mounted with v4
    - short tests with Aquaman (2018) EAN 5051890317377 english E-AC3 with Atmos plays flawless all other HD audio tracks with dropouts (2x DTS-HD, 1x TrueHD/Atmos)

    I tested by seeing at leats 10min (if no dropouts) to be sure. Mostly in less then 5min i did get a droptout. Switched devices and setting many times. At the moment that looks like a N100 problem.
    Now i tested my NUC12WSKv7 and it has the same dropouts.

    NUC12WSKv7
    - created a USB disk with a new clean installation of LE11 and local data to play
    - so far the same problems as the PN42
    - 2x movies both 2 errors https://sky42.libreelec.tv/testing/adl/ko…C12WSKv7.log.gz


    I will formalize the test and create some clean logs.

  • Time to upgrade my NUC. What's hot today?

    smp do you know how to build a version with pipewire? I dont. To put on some more versions to boot is not problem, there are alraedy 5 different LE version on there that i can boot with a grub2 menu (with the remote :)

    infoalter i agree to have N100 working would be nice. The N6000 has no hardware AV1 decoding, the N100 does because of the Gen12 GPU and is around 20% fater.

    I have still a 2nd N100 here and will test that today. A fanless HUNSN BM34 for less then 200 Euro as barebone, BUT no USB wakeup or CIR. WOL is working and power consumtion in S3 standby is very low and USB wakeup from S3 works. No USB on the back side, that is a bit impractical. It is fanless and not a bad chassis. They even give me a PXE capable BIOS (was not on there) after asking. The preassembled one i have has a DDR4 2666 not 3200 and it is a really cheap M2 SATA SSD. It is a very nice box.

    Now i will free my Desktop to test NUC12i7.

    yamcenutzer no CIR options in the BIOS but HDMI-CEC

  • Time to upgrade my NUC. What's hot today?

    oh boy ... i did a bit more of a playback test on LE11
    - Video all fine from Mpeg2, H264, HEVC up to 4k with HDR (on my LE BT2020 version)
    - did not yet test AV1 and LE12

    - HD Audio is not fine on LE11
    So i need to warn everybody of audio dropout for ALL HD Audio passthrough on my ASUS PN42. 1st check on a i3-8100 HDMI 1.4 i could not reproduce. Dropouts in the latest after around 5min. Sometimes every 15sec 2x-3x times.
    Used 6 different remux from BD made my self. DTS-HD 5.1/7.1, TrueHD with/without Atmos 2.1 Mbit - 6 Mbit have all dropouts. DDP 7.1 with Atmos is fine 1.5 Mbit.

    Will test more and come back
    - Denon X6700H and LG 55E6D only HDMI connections, no ARC, no CEC
    - ASUS PN42 HDMI 2.0 a or b (not sure)
    - Asrock B360 ITX/ac HDMI 1.4 (so far could not reproduce) with i3-8100
    - NUC8i7BEH HDMI 2.0a (need to free it 1st)
    - maybe NUC12WSKv7 (but that is even more work because it is my desktop)
    - maybe RPi4 too
    - maybe Vero 4k+ with OSMC too

    Anybody has a full fledged test plan and samples.
    I will manage to create one my self, just asking to save time.

    1.
    - only HDMI
    - no ARC
    - no CEC
    - PN42 -> Denon -> LG TV
    - only passthrough except e.g. AAC that can not be passthrough

    2.
    - from SD to 4k HDR (with my BT2020 community build)
    - Mpeg2, H264, HEVC
    - no AV1 test so far

    3.
    - nearly all HD Audio has very short audio dropouts for like half a second from 1 up to 10 times in 5min, but at least one TrueHD did not dropout in the 1st 5min
    - all audio works with passthrough (not yet DTS:X tested, have only 1 remux)
    - now i will investigate the HD Audio dropouts, but that will mayby take some days to test

    4.
    - remux of DVD, BD, 4k BD
    - H264 720p50 Live Streaming ARD/ZDF
    - 720p AVC / 1080p HEVC streaming files
    - i do have live TV with tvheadend and VU+ plugin but do not use it

    adam.h. no not that one, the barebone N100 version and i put a 8GB DDR4 3200 and Samsung NVMe SSD in there

  • Time to upgrade my NUC. What's hot today?

    I have a ASUS PN42 with Intel N100 for a week or 2

    - fanless !!!

    - CIR RC6 works and wakeup from S5 too

    - HDMI CEC with extensiv BIOS config (not tested but saw the settings)

    - works.geat (for me) with LE11

    - wakeup from S5 with USB or IR

    -power consumption is like a RPi4 with USB3 SSD

    - BT and WiFi ofc

    - as fast as my i3-8100 HTPC but less then a 1/3 of the power consumption

    - decodes AV1 in hardware (my i3-8100 not)


    Even StandBy and WakeUp works. Most of the time the bios I can see too on my LG with a Denon AVR.

    This Hardware is great. The power button is a bit bright. I did get it for 220 Euro "used" at Amazon.

  • LE 11.0 added lvm2, luks (dm-crypt, veracrypt), mdraid, ext4 encryption

    Sorry LE and WLAN we are not friends. I always use wired.

    The .kodi mount in a extra partition I did too for testing. You even can do that with ext4 FS encryption without extra partition. But the ext4 in FS encryptuon is kind of bad documented.

    My goal was/is the same: take out one fully encrypted system and all the rest is gone no cache or metadata left.

    NBDE with tang and clevis is very cool for that. I do that all the time with any RHEL and clones. At work with hundreds of servers.

  • LE 11.0 added lvm2, luks (dm-crypt, veracrypt), mdraid, ext4 encryption

    le3b nice to see somebody else to be interessted to encrypt user data

    here is the place you can use
    https://github.com/sky42src/Libre…ripts/init#L604
    last line in your "mount-storage.sh" should be
    mount_part "$disk" "/storage" "rw,noatime"
    or something else that does the job

    for fast testing i use kernel command line and nfs backend (that is encrypted)
    add to your kernel command line "ip=dhcp disk=NFS=server:/kodi/21/client,vers=4 ipv6.disable=1" normally in /flash/syslinux.cfg
    that works with the official image too

    And i already build LE12 Generic, but did not upload it or opened a new thread for it. Testing it for 4 days now with my new Intel N100 box (not yet checked out the part encrypotion).
