Deri could you please test with this build:

https://www.horus.com/~hias/tmp/libreelec/LibreELEC-RPi4.arm-11.0-devel-20221102193102-92f9d97.tar

It includes the latest 6.0.6 kernel with the fix from 6.1

so long,

Ah, and our config.txt might also play an important role. The LE specific settings are in distroconfig.txt (which is included in config.txt)

Most important bit for RPi4 is using 512MB of CMA memory - otherwise several 4k HDR files lead to a crash (the default of 256MB CMA is not enough).

We are using pretty stock RPi kernels, from https://github.com/raspberrypi/linux (rpi-5.10.y branch for LE10, currently rpi-6.0.y for LE11, we'll switch to the LTS kernel, probably 6.1, when it's out as RPi folks use LTS kernels as a base, too).

We only apply a few patches on top, you can find them in the packages/linux/patches/raspberrypi directory, eg here for LE10:

The only somewhat important patch is

linux-020-eld-constraints-for-compressed-formats.patch - it's a bit hacky but helps getting TrueHD/DTS HD passthrough with some TVs/AVRs (most TVs/AVRs are fine without it).

MatteN for the last time: please provide logs. No one knows if your issues are related to that, USB, your devices or whatever.

Deri can you please test with the latest nightly build (2022-10-30)? It includes an RPi kernel update with the change mentioned by popcornmix

You could have a look at the HDFury Acrana https://hdfury.com/product/4k-arcana-18gbps/ (or Vertex2 https://hdfury.com/product/4k-vertex2-18gbps/ if you need eARC from two instead of 1 HDMI inputs)

I don't own one of these myself but the HDFury products have excellent reputation. The price point isn't exactly low so depending on which TV you have swapping that out could be an alternative, too

It's definitely needed as otherwise the maximum will be 4kp30 at RGB 4:4:4 8bit - usually the TV also advertise the HDMI 1.4-compatible "fake" 4kp60 YCC 4:2:0 mode but the RPi doesn't support it (only 4:4:4 and 4:2:2).

No idea about that Asus thing though.

How did you set up your whitelist, did you follow the recommendations in the wiki or did you also include SD modes? If you did the latter: don't do it.

Anamorphic videos (like on DVDs) are a bit problematic and ISTR LE 9.x had some issues with those. Please test with LE 10.0.3 (which, BTW still has Estuary as default skin so that should not hold you up).

Playing DVD or BluRay images over the network, whether extracted or not, is often problematic. As you can see in your log kodi has to open dozens of files per second during playback as the video is split into thousands of tiny pieces. The better solution is to rip the main movie to mkv, those are far less problematic than dvd/bluray images.

The stutter-every-second issue sounds like the screen is running at 25 or 50Hz but you play a 23.97 or 24fps movie - the log you provided though shows the mode had been switched to 23.97. You could try changing the adjust refresh rate setting to "always", maybe that helps.

We really should change that text about RPi (esp RPi4), lots of things have been fixed and improved in the last year

In several aspects, esp HDR video and HBR audio it's now ahead of other devices.

There's nothing obvious in the logs except you are running a rather old LE version, 9.2.8, which is EOL now (latest release is 10.0.3) and you are playing a bluray image over nfs (which may or may not be problematic - never tried that myself).

Another thing worth looking into is your TV settings. Best to turn off all picture/video "enhancement" stuff, they usually just make things worse (especially Samsung TVs still seem to come with terrible defaults). Search eg on rtings.com for your TV model to find some info about recommended TV settings.

so long,

Hias

If you haven't setup whitelist and enabled refresh rate switching then the GUI mode will be used for playback - and if you try playing eg an SD or HD 50fps file at 4kp30 things will go south.

If it still doesn't work then post a debug log.

so long,

Hias

Most likely you are running at 4kp30.

Configure kodi as described in the wiki https://wiki.libreelec.tv/configuration/4k-hdr and optionally add hdmi_enable_4kp60=1 to config.txt to get 4kp50/60 modes as well.

Yes, the "Power" seems to ignore the disable setting!

The safest way to turn off the PWR LED on all Pis with either old or new firmware is to use the default-on method but declare the output as being active-high:

Code

dtparam=pwr_led_trigger=default-on # The default
dtparam=pwr_led_activelow=off

RPi0-3 don't have H265 hardware decoders but older LE (more specifically: ffmpeg) versions contained some clever code to offload some of the heavy lifting to the GPU. So H265 up to HD, with not too high bitrate, was playable on RPi 3.

Unfortunately this code could only work with the legacy proprietary graphics drivers so it's no longer available since LE10 (and has now been removed in latest ffmpeg versions).

Just use the RPi imager on a PC to create an eeprom/bootloader recovery SD card and then put it into your RPi

I think you may be out of luck, the soundbar only seems to have an HDMI eARC input and no standard HDMI inputs where you could connect the RPi to.

You have to connect the soundbar's eARC input to an (e)ARC output of your TV.

It might be worth to contact suntdek support and ask for open source drivers with source code - with their closed source binary drivers it's impossible to debug any issue.

In the (likely) case they won't do that it's up to sundtek to debug the issue - so again, ask sundtek support about that.

You have to name the keymap custom_remote.toml if you use the new toml format - keymaps without the .toml extensions are considered to be in the legacy format.
