    OK, I would say most likely another RPi 4B will behave same with your TV.

    I suppose your TV has more HDMi ports - try all of them (always reboot RPi), check if there are some settings related to HDMi input(s) in your TV and modify if so (overscan settings - turn off, set PC mode etc... ). Try to set another display mode(s) on RPi (on Raspberry PI OS) - lower resolution / FPS rate in accordance what you see in EDID file that your TV supports. Try to set the same display mode as your tablet is using (including FPS rate).

    Also you could even try another Linux distribution (Ubuntu is supported on RPi 4B as well) to check if there's same behavior with your TV or not...

    BTW. I am using 3m long 4K micro HDMI / HDMI cable (PremiumCord, bought locally from trusted distributor), even cheaper than yours but it looks more thick & robust (UL20276) and works perfectly with my RPi 4B & several HDMi displays / TVs at all supported resolutions.

    Sorry I feel lost because I don't understand anymore what exactly works and what does not.

    The cable specification looks OK but you should be able to test and confirm if it's really working properly or not. So at first, I would test with latest official Raspberry PI OS which should work with both your HDMI devices (and even at the same time if you already have 2 HDMI cables).

    Then you should be able to say if the HDMI cable(s) are OK, if they work properly and reliable at maximum resolution etc.

    Then I would play with LE, default config without any overlays added. As we know LE does not support more than one display, only HDMI0 port (next to the power connector) needs to be used for video, HDMI1 can be used for audio output (with 2 HDMI cables this is also the good test option, to see if you are able to make at least audio working on your TV when video does not work). So if you know what are you doing, you can identify what the issue reason could be. Of course it needs some (huge) time to try several options...

    I would try to add the non-default overlays to already fully working LE only. Unfortunately I have no experiences with the mentioned overlays as I don't use them. But I suppose they may need to configure some other parameters as well.

    I think I'm going to roll back to version 9.2.6 because I'm tired of testing lots of things but kodi doesn't boot.


    Which eeprom version do you recommend for booting 9.2.6 ?

    I wouldn't go back to earlier LE versions but I don't think that latest bootloader should prevent LE 9.2.6 from boot. If so, you need to describe what exactly happens at boot, when it hangs, if you see something on screen, what LEDs are doing etc...

    If it boots in fact but Kodi does not start (as you say), then you can login through SSH and you may check the logs.

    What's your current bootloader configuration (rpi-eeprom-config)?

  • Restart audio after waking from suspend

    Yes, try to edit the script to this form:

    Bash
    #!/bin/sh
case "$1" in
   post)
     sleep 5
     xrandr -display :0 --output HDMI1 --mode 1920x1080 --rate 59.94
     sleep 5
     xrandr -display :0 --output HDMI1 --mode 1920x1080 --rate 60
     ;;
esac

    It's also possible to run the script by Remote Control but it needs some more configuration.

    At first, try to run the irw command in SSH console, then push your favorite button(s) on Remote Control and put a response(s) here (if any).

    Exit from irw by pushing CTRL+C.

    In case there were no responses, the preferred key needs to be mapped first so it would need even more tasks to do... Then try to run this command and put a response here: cat /storage/.config/rc_maps.cfg

    Let me know results and then I could tell you more.

  • Restart audio after waking from suspend

    Perhaps you could try this from SSH console:

    1) make sure your current script is executable:

    Code
    chmod +x /storage/.config/sleep.d/99-toggle_rate.power

    2) test after resume from suspend if your script works:

    Code
    /storage/.config/sleep.d/99-toggle_rate.power post

    3) if it works as expected, create the service which should run your script after resume from suspend:

    4) enable the service and test if it works:

    Code
    cd /storage/.config/system.d/
systemctl enable kodiresume.service

    I am not sure if it's error free but can't test it in my (different) environment completely. So it's up to you.

  • Restart audio after waking from suspend

    OK, use nano editor:

    nano /storage/.config/sleep.d/99-toggle_rate.power

    use cursor keys to navigate to both HDMI1 words and insert - character to change them to HDMI-1

    Then press CTRL+X and confirm by Y to save the file.

    I recommend using putty as SSH client.

    If LE is refusing the connection, restart the SSH service through Kodi menu Settings - LibreELEC - Services - SSH (disable and re-enable),

    then connect through putty again.

    OK, so the better steps should be:

    - connect the PC monitor to RPi (use HDMI0 port which is next to power connector)

    - reboot RPi

    - login to SSH console and run getedid create

    - run edid-decode /storage/.config/firmware/edid/edid-HDMI-A-1.bin

    - save the text output and share it here as link (use pastebin.com)

    - connect the TV to RPi (use HDMI0 port which is next to power connector)

    - reboot RPi

    - login to SSH console and run getedid create

    - run edid-decode /storage/.config/firmware/edid/edid-HDMI-A-1.bin

    - save the text output and share it here as link (use pastebin.com)

    Maybe there is a compatibility between the firmware and the version I try to use

    This won't be the case otherwise it wouldn't work with your PC monitor as well. And I am running two RPi 4B with latest firmwares & latest LE 10 Nightly builds without any video issue.

    It's hard to say what's wrong at your configuration but I would start again with defaults. Also I would decode the EDID files of your PC monitor & TV and compare them ( edid-decode /sys/devices/platform/gpu/drm/card0/card0-HDMI-A-1/edid ).
