No video out when I first start my RPI4 and afterwards start my tv

Edit: it is fixed:

I followed this https://wiki.libreelec.tv/configuration/edid#intel and follwed the intel steps, but the extlinux.conf or syslinux.cfg didn't exist, so instead I added

drm.edid_firmware=HDMI-A-1:edid/edid-HDMI-A-1.bin video=HDMI-A-1:1920x1080M@60D

To /flash/cmdline.txt

Orifinal problem:

I made a git bug report, but I wanted to know if someone else has the same problem?

Describe the bug

When I boot my raspberry pi an afterwards start my tv, I don't get video out. Even when I unplug and plug in the hdmi after they both are started.

But when I first start my tv, and then boot my rpi it works fine

To Reproduce

Steps to reproduce the behavior:

1. Install 9.95.5
2. start RPi4
3. Start soundbar (HEOS) and tv

Informations

• LE Version: 9.95.5
• Hardware Platform: RPI4

Log file

Log from when the problem exists: http://ix.io/3rP7

Log from when I first start the tv: http://ix.io/3rPa

Additional context

It worked fine when using LE 9.2.X

I have my rpi4 connected to my soundbar, and the soundbar to the tv

Yeah, but someone on github commented this:

Quote

I'm closing the ticket because this is not a bug, it's the expected behaviour now RPi devices in LE10 no longer use legacy vendor drivers (behaviour is now consistent with other LE devices since ~2012).

Follow the section on Intel GPUs https://wiki.libreelec.tv/configuration/edid and repeat for your RPi4. If you need further support please start a thread in the forums.

So I'm looking at that now.

I fixed it, see edit
