The two most common issues with USB drives are power consumption and dodgy USB controllers/bridges in the USB drive.

First make sure the drive is powered properly (RPi can only supply a very limited amount of power). If you are using a drive with it's own power supply then you should be fine. If you are using a bus-powered drive and connect it to a powered USB hub.

If your drive has some dodgy USB controller then first try with the current LE11 nightly build. It comes with a lot newer linux kernel and might already have workarounds for the dodgy controller in place.

If this doesn't help and/or you want to run LE10 then first try booting from a SD card (or your USB key), plug in the drive and post a full log (run "pastekodi" via ssh or use the log upload function) - this will give us some information about your drive.

You can also check dmesg/journal or lsusb output yourself.

The info you/we need are the manufacturer and model of the drive and the USB vendor and product id.

Searching for that eg on the RPi forum https://forums.raspberrypi.com/ might already give you the info you need - usually some usb quirks that you need to add to cmdline.txt.

The most common issue is broken UAS support in the drive, in that case you need to add something like usb_storage.quirks=1234:5678:u to /flash/cmdline.txt (where 1234:5678 need to be changed to the USB vendor/product ID of your drive).

You could try installing permanent EDIDs with "getedid create" (run that when the AVR showed up in audio settings) and/or add "vc4.force_hotplug=3" to /flash/cmdline.txt

Depending on the actual issue one of those options might be sufficient or you might even need both.

BTW: To remove the permanent EDID run "getedid delete" and reboot - you also need to do that if you want "getedid create" to read new EDIDs from TV/AVR (eg when switching TV/AVR or HDMI ports).

I'd really stay away from 1GB.

Kodi has rather long standing and yet unresolved issues with image handling (eg with pictures but also movie etc artwork) and is consuming too much (graphics) memory - which often leads to out-of-memory crashes.

We regularly see these issues on RPi2/3, which have 1GB.

It depends.

I usually whitelist 720p, too, so my TV (LG 55C8) does the upscaling.

But whitelisting SD has several drawbacks:

First of all GUI overlays, subtitles etc will then be rendered at a low resolution and look very ugly.

For SD material there's also the anamorphic problem, where pixels aren't square and kodi doesn't handle that too well and kodi doesn't signal 4:3/anamorphic 16:9 to the TV.

Lastly my TV has the annoying behavior of always cutting off overscan in SD resolution so parts of the GUI are missing.

If you can live with the limitations you are free to enable SD output but it's a lot more hassle free to just let kodi upscale SD to HD.

Stay away from the 1GB model, that's not enough for LE/kodi and IMO 8GB is overkill for LE.

So that leaves the 2 and 4GB models.

I usually chose the 4GB models (but that was before the chip and availability crisis and price difference between 2 and 4GB was small) but LE will run just fine with 2GB so pick whatever you can get.

uncomment means you have to remove the "#" at the beginning of the following two lines. That part of config.txt should then look like this:

# uncomment to enable analog audio output
dtparam=audio=on
audio_pwm_mode=1

Quote from PiMONSTER

Just updated by selecting 10.0.3 under channel. Seems OK.

BUT ...... the firmware update refuses to update.

selected and rebooted twice to no avail.

Still offers update from the installed January edition.

On reboot a screen does indicate update available and then rapidly disappears.

Remind me what are the commands to update via the terminal ?

I assume you are using an RPi4 and try to update bootloader firmware (which doesn't work with USB boot yet). In this case run

rpi-eeprom-update -a

and then reboot.

The kernel update https://github.com/LibreELEC/LibreELEC.tv/pull/7087 has been merged, the next nightly build should contain the fix.

Please run the following command while connected to your Grundig TV and post the URL you got:

modetest | pastebinit

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

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.
