There is only one librelec image with kodi 18.3
LibreELEC (Leia) 9.1.002 ALPHA – LibreELEC
You can get it for rpi4 here in archive:

Hi,
It looks like Asus has ported some raspberry Pi audio hats to his own tinkerOS
debian_kernel/sound/soc/rockchip at develop · TinkerBoard/debian_kernel · GitHub
But libreelec is using generic rockchip kernel,which is lacking those modules.
kernel/sound/soc/rockchip at develop-4.4 · rockchip-linux/kernel · GitHub
So... Using libreelec with tinkerboard + hifiberry dac is not impossible, but won't be easy.
Maybe try tinkerOS first, it should allow you to install kodi.

Connect with ssh, then use this command:
bcmstat.sh
or, for more informations
bcmstat.sh xype
(Ctrl+c to exit)

You have a lot of errors about thoradia addons.
Try to remove them.

Well, pi4 will not have enough cpu power to software decode anything higher than 1080p.
So your only option is to use HEVC files (sometimes named h265, or even x265)
Maybe you can use handbrake to convert your vp9 files to hevc.
HandBrake Documentation — Official presets
Or with ffmpeg
Convert YouTube HDR (vp9.2) video to HEVC HDR with ffmpeg - Super User
But the process will probably be very (very) slow

It looks like it is trying to change the framerate on the fly.
Can you try with "adjust display refresh rate" set to "on start / stop"?

Could you state what codecs your files are?
RPi4 has hardware decoding up to 1080p with h264 codec and up to 2160p with HEVC.

I also get the infamous "drop frames before first appearance of srt subtitles" in a lot of files. This happens every time a new block of subtitles appears after some time without dialog.
Are that known issues?
About that issue, I have good results by disabling the "dirty regions" functionality.
Add a file /storage/.kodi/userdata/advancedsettings.xml
Containing:
<advancedsettings>
<gui>
<algorithmdirtyregions>0</algorithmdirtyregions>
</gui>
</advancedsettings>
Got the idea from this thread:
Kodi's Dirty Regions - ARM GPU Tech - improving Kodi rendering performance

If you remove
dtparam=audio=on
And add
dtoverlay=hifiberry-digi
Is it working better?

Using the same addon/plugin as grael, it is working at 1080p, no overclocking with passive cooling only.
Yes, most of the time, 1080p works without overclocking.
But some heavy scenes may stutter sometimes.
For instance the opening scene of Black Mirror (5x01) Striking vipers.
By the way, I've had an update notification for widevine this morning, but the new version is performing far worse than previous version...
Good one:
LibreELECPi4ssd:~ # md5sum /storage/.kodi/userdata/addon_data/script.module.inputstreamhelper/cdm/libwidevinecdm.so

Bad one:

I have it working fine on my Rpi4.
GitHub - CastagnaIT/plugin.video.netflix: Inputstream based Netflix plugin for Kodi
With proper cooling, power supply and overclocking (2 GHz here) it's even working smooth with 1080p

Not yet. Maybe in a few months (no guarantee)
-
Make sure to use the hdmi connector 0 (close to usb-c power socket)

You need to read the first page of the "LibreELEC (Leia) 9.2 ALPHA1 with Raspberry Pi 4B Support" thread

Hello,
Crackling sound here too on a raspberry 3B+.
I2s output.
audio_pwm_mode=2 didn't fix.
Reducing audio level in kodi by 2 steps make it disappear but a better fix is welcome
Edit : still slight clipping distorsion with 2 steps reduction. 3 steps is safer with loud tracks
audio clipping distortion on i2s output is fixed with this firmware
Thanks guys!
