imforumman and others affected by the issue:

The workaround is now included in official LE10 nightly builds (starting with today's 20220610 build)

https://test.libreelec.tv/10.0/RPi/

Add vc4.force_hotplug=3 to /flash/cmdline.txt to activate the workaround on both HDMI ports.

Also please try with 1 and 2 instead of 3 to activate it only on the first or second HDMI port and report back which values work for you.

so long,

I did try with the LE11 https://www.horus.com/~hias/tmp/libr…608-bbb7ee2.tar.

I first updated in the update storage, removed the vc4.inval_delay=0 vc4.cec_debug=0x100 and added vc4.force_hotplug=3 and it does work for me:

LibreELEC (HiassofT): devel-20220603141608-bbb7ee2 (RPi4.arm)

LibreELEC:~ # cat /proc/cmdline

coherent_pool=1M 8250.nr_uarts=0 snd_bcm2835.enable_compat_alsa=0 snd_bcm2835.enable_hdmi=1 smsc95xx.macaddr=E4:5F:01:6E:EF:84 vc_mem.mem_base=0x3ec00000 vc_mem.mem_size=0x40000000 boot=UUID=0503-3724 disk=UUID=35edecc5-1628-4f09-b69a-bd0498e093cd quiet vc4.force_hotplug=3

As I'm using the left HDMI port of the RPI4,

vc4.force_hotplug=2

did not work but

vc4.force_hotplug=1

is working.

Here with 2000 value, which is working for me:

LibreELEC:~ # cat /proc/cmdline
coherent_pool=1M 8250.nr_uarts=0 snd_bcm2835.enable_compat_alsa=0 snd_bcm2835.enable_hdmi=1  smsc95xx.macaddr=E4:5F:01:6E:EF:84 vc_mem.mem_base=0x3ec00000 vc_mem.mem_size=0x40000000  boot=UUID=0503-3724 disk=UUID=35edecc5-1628-4f09-b69a-bd0498e093cd quiet vc4.inval_delay=2000

And this one with vc4.inval_delay=0 vc4.cec_debug=0x100 which also works:

LibreELEC:~ # cat /proc/cmdline
coherent_pool=1M 8250.nr_uarts=0 snd_bcm2835.enable_compat_alsa=0 snd_bcm2835.enable_hdmi=1  smsc95xx.macaddr=E4:5F:01:6E:EF:84 vc_mem.mem_base=0x3ec00000 vc_mem.mem_size=0x40000000  boot=UUID=0503-3724 disk=UUID=35edecc5-1628-4f09-b69a-bd0498e093cd quiet vc4.inval_delay=0 vc4.cec_debug=0x100

Thanks for your quick reply popcornmix.

It was once again my bad as I put vc4.inval_delay=5000 after a line break and not immediately on the same line after "quiet" on cmdline.txt

And I'm happy to say that it is working with this value!!! It does not turn on after being powered off!! I'm so happy now!

hastebin

grep . /sys/module/vc4/parameters/*
/sys/module/vc4/parameters/cec_debug:0
/sys/module/vc4/parameters/fkms_max_refresh_rate:85
/sys/module/vc4/parameters/inval_delay:5000
/sys/module/vc4/parameters/tv_norm:(null)

LibreELEC:~ # cat /proc/cmdline
coherent_pool=1M 8250.nr_uarts=0 snd_bcm2835.enable_compat_alsa=0 snd_bcm2835.enable_hdmi=1  smsc95xx.macaddr=E4:5F:01:6E:EF:84 vc_mem.mem_base=0x3ec00000 vc_mem.mem_size=0x40000000  boot=UUID=0503-3724 disk=UUID=35edecc5-1628-4f09-b69a-bd0498e093cd quiet vc4.inval_delay=5000

Ok this time I tried with the correct test build and here is my result with vc4.inval_delay=5000:

hastebin

Please note that /sys/module/vc4/parameters/inval_delay value is always 1000 regardless using vc4.inval_delay=5000 or vc4.inval_delay=0 vc4.cec_debug=0x100 at cmdline.txt

And it did not work for me unfortunately.

Ok then It seems that the update did not worked as I do not have the inval_delay value.

I extracted the content of the tar of the test build into ./update but I will just put the tar file into that folder and try again tonight.

Sorry for the mistake.

This is the log with vc4.inval_delay=5000 at the end of cmdline.txt:

hastebin

It did not work either T_T

This is the log with vc4.inval_delay=0 vc4.cec_debug=0x100 which is not working for me as well

hastebin

By the way, how to make sure that the update occured?

Thank you

Hello popcornmix

Thank you for your reply.

I did put the test build by SSH in /storage/.update and reboot.

Unfortunately it did not work for me and the projector turned back on again.

Please find my log here: https://paste.kodi.tv/dudonubezu

I will try vc4.inval_delay=5000 and let you know

Without waiting, please check my log on https://paste.kodi.tv/adijamewoy starting from line 7301 (I think) where I press the power button from my Samsung remote to turn off all the devices, then I press absolutely nothing and all the devices wake up. Then I just press some button to go to the Kodi Logfile Uploader. "Recorder" is actually the Raspberry device. Thank you for your help!!

Hello everyone. I just created this account because I have the same issue and I am super willing to help and test since with very latest release, LE will be an almost perfect player for me since this issue is extremely frustrating.

I did see that developers tried to solve the issue with a test build but so far only Shazb0t replied so I guess I have to do my part.

My setup is RPI4B 4gb with LE10.0.0.2 connected to Sennheiser Ambeo soundbar which is connected by e-Arc to the Samsung LSP9T projector.

After turning off the projector using the projector's remote, it does put the soundbar and the projector in standby and wake up everything a few seconds later. The only way to put everything in standby is to switch to another device (in my case a Fire TV stick 4K Max) and turn off from that. At first I thought it was a normal behavior since the only release I installed was the 10.0.0.1. Before that I was using the Nvidia Shield.

I tried several different settings in the Input CEC and choose to put the RPI in suspend, hibernate but it does not work.

I regularly check this post and try the different build eventually as well as posting the log if needed.
