RP5 with 12.0.2 has no signal on 4k Samsung TV but works on a monitor

    I am very new to LibreELEC and read about edid here: https://wiki.libreelec.tv/configuration/edid

    I also saw a similar issue here:

    [RPi5] No HDMI Signal on AVR/TV

    Hi,

    I have a Ri5 with Libreelec (latest stable build) installed and when connecting to to my TV via the AVR, I get a no signal on the display.

    I have tried the steps for using getedid and that did not resolve the issue. I then tried the advice on setting the GUI to 1080p@60 refresh rate and whitelisted the displays modes, however, that still did not fix the issue.

    It works 100% fine when connected to a monitor, just not the TV/AVR setup.

    My logs from pastekodi can be found here …

    I did some tries to connect the TV in different HDMI IN and also combined with trying both HDMI ports on the RP5 with no success. About create edid command, should I run it when I have it working in a regular monitor then try on TV? I am a complete newbie so I would appreciate if you treat me like a child explaining :S

    Append video=HDMI-A-1:1920x1080M@60 to boot params in cmdline.txt and see if that resolves things? If not, ensure you are using a 4K certified micro-HDMI to HDMI cable and not micro-HDMI to HDMI adapters (which often cause issues), or if using an Argon case; remove the board from the case and connect direct to the TV to prove that the adapters in the case are causing the issue.

    If none of that works, power off, remove the SD card, power on to the firmware screen and check it reports 'EDID' on the active HDMI connection (use the port nearest the power connector). Report back.

    chewitt thanks a lot for your answer. After searching more I found a way to SSH into LibreELEC and use the ``getedid create command. After that, the Pi started working full HD on the TV (which for me right now is not bad). It also worked out-of-the box with the remote control of the TV. The big problem now is that, no matter what I do, there is no volume at all from videos and music (even when I put the volume on maximum). I see I can control volume from the remote control also but does not seem to work.

    The monitor that you captured EDID data from has no speakers, hence Kodi detects no audio capabiities. EDID capture is not the solution to your problem.

    Your setup is not receiving correct EDID and thus the picture is not being interpreted correctly. This is normally caused by bad cables or adapters and the correct solution is having EDID correctly exposed "normally" .. the get edid script should only be used for faking presence of the TV/AVR to workaround boot order problems.

    chewitt thanks again, I did some more hours of tests. I am using 0 adapters, and a certified 4k@60Hz cable by Amazon basics:

    I finally was able to SSH into LibreELEC while connected to the TV, then I did getedid delete and getedid create, this changed my cmdline.txt to:

    Code
    boot=UUID=2001-4441 disk=UUID=30f5d869-400e-4a82-8b7b-a5173e9001ba quiet console=ttyAMA10,115200 console=tty0 drm.edid_firmware=HDMI-A-1:edid/edid-HDMI-A-1.bin,HDMI-A-2:edid/edid-HDMI-A-2.bin video=HDMI-A-1:D video=HDMI-A-2:D

    with the monitor it was:

    Code
    boot=UUID=2001-4441 disk=UUID=30f5d869-400e-4a82-8b7b-a5173e9001ba quiet console=ttyAMA10,115200 console=tty0 drm.edid_firmware=HDMI-A-2:edid/edid-HDMI-A-2.bin video=HDMI-A-2:D

    and after getedid delete it was just:

    Code
    boot=UUID=2001-4441 disk=UUID=30f5d869-400e-4a82-8b7b-a5173e9001ba quiet console=ttyAMA10,115200 console=tty0

    The problem is that in none of them I was able to hear audio! Do you have any idea why should be then?

    Pastebin a Kodi log (SSH in, run "pastekodi") so that we can see what config is being used. I'll say again (third and final time) that forcing EDID is not the solution to your problem. Also use the HDMI port nearest the power connector.
