HDMI-CEC work on PINE RockPRO64 until TV goes off and on cycle

Hi,

just tested 10RC1 (9.97.1) without luck.

knaerzche any chance to have time to continue on this issue?

Hi!

This is still very real problem with released LE 10.0.0. Basically makes LE10 unusable, had to revert back to LE9.2.

maddoxik · September 6, 2021 at 1:09 PM

munninen Absolutely agree!

Nevertheless, I checked the issue again and found that just restarting Kodi systemctl restart kodi.service solve the issue. Which points me to suspection that the issue is not in the hdmi-cec driver itself but somewhere in the Kodi, or maybe specificaly in libCEC library/addon.

This is actually very helpful, thanks for reporting.

Have you tried playing with any of those CEC-settings in System->Inputs->Peripherals->CEC Adapter - espacially those for "When TV is switched off" or "Action when switching to another source"? Sorry that I can do only guesswork here again: Since I can't reproduce this issue here, I can only guess what eventually needs to be changed.

(Not sure it is required, but better restart kodi after changing any of these settings)

I tested a lot of combination in CEC Adapter setting but none works. Usually it is same or worse (RC doesn't work even kodi service restart).

Nevertheless I found two maybe interesting things:

1) I turned on Kodi debug logs for libCEC. Kodi is trying to change physical address to "FFFF" but there is no such value in CEC Adapter

TV is on and I put it into standby mode:

2021-09-07 19:04:21.604 T:2770 DEBUG <general>: PushCecKeypress - received key a8 duration 73

2021-09-07 19:04:27.169 T:2770 DEBUG <general>: CecLogMessage - >> 0f:36

TV is in standby mode and I turn it on via RC:

2021-09-07 19:04:40.867 T:2770 DEBUG <general>: CecLogMessage - CLinuxCECAdapterCommunication::Process - CEC_DQEVENT - CEC_EVENT_STATE_CHANGE - log_addr_mask=0000 phys_addr=ffff

2021-09-07 19:04:42.879 T:2770 DEBUG <general>: SetConfigurationFromLibCEC - settings updated by libCEC

I tried to change physical address in the CEC Adapter settings without any effect.

2) When I run cli command cec-ctl --tv -S while TV is on, Kodi up and RC works properly, immediately after execution RC stops working. I have to restart Kodi service to have RC working again.

I've just upgraded to the test img from the day before yesterday and still nothing new on this problem.

It's really frustrating have to keep restarting the Kodi process each time the tv is turn off and I turn it on to watch something.

Everybody having this issue on Rock64 (I didn't bother to build images for other boards yet) please see: https://github.com/LibreELEC/Libr…mment-944993387

Thanks for the promising news!! Unfortunately I can't test the img. My box is a RockPro64 (RK3399), not a Rock64 (RK3328).

This fix has been merged last couple of days and it's included in RK nightlies available at https://test.libreelec.tv/.

I guess (hope) it was the same issue for all of you. Note that CEC is not available immediately after TV is swithed back on, you'll have to wait some secs (depends on TV) ... for debugging: https://github.com/LibreELEC/Libr…mment-944993387

I just tested the RK nightly for RockPro64 (20211028) and remote controller works again after TV goes back from standby!

knaerzche thanks for your time and help

Thanks for reporting back.

The fix will also be included in LE 10.0.1 bugfix release (which I suggest to use) - it's expected to be released soon-ish.

knaerzche Sorry for the delay and thank you very much!!

I can attest that it works perfectly after your patches.
