Hdmi-CEC and OSMC

Help and Support
1

Hi,
I had a corrupted SD card so I had to reinstall OSMC to a new card. RaspberryPI2 B with 1G of RAM.

Initially everything was working fine (well, I had to reconfigure everything), but once I just realized that the remote doesn’t work as it used to. And it worked initially with the new system also. But now it stopped working with TV. It’s a Samsung.
On the TV the Anynet+ is enabled, but when I go to find devices it doesn’t find any.

It worked, but now it doesn’t work…

Debug logs can be found here:

Could it be that I have enabled a tty console also (so when mediacenter service is stopped I got a text console on screen, instead of rebooting kodi)?

When kodi is not running the cec-client’s outputs this:

osmc@osmc:~/.kodi/temp$ cec-client

Could someone guide me to the correct direction where to look because now I am clueless…
Thanks,

First thing to try is removing the power to the TV and the osmc device for a few minutes. They need to be off and not in stand by

Running CEC-client will break CEC input in Kodi until you reboot the RPi (not just restarting Kodi) just FYI. If this is a clean install then it should have been enabled by default but just in case you might check settings>system>input>peripherals> to be sure.

This is somekind of black magic.

I did what you suggested: turned off, power removed (pi + TV), 5mins, turned back everything.
Thanks a lot for your help, now it works.

ok, good to know. Anyway, when I executed cec-client, libcec didn’t work before either on Kodi.
And yes, I checked. It is enabled on Kodi, enabled on TV.

The solution was the good-old powercycle (with a little rest between trurning off and on). Is the libcec std designed by Microsoft?? :slight_smile:

br,
S

Not really. TV’s sometimes get messed up with the CEC and a hard boot is the only way to get the TV to start fresh with new CEC assignments. In the same way a downstream device can get stuck using a device identifier on the CEC bus that either conflicts or the TV doesn’t know about and rebooting the device is a way to ensure a new poll gets requested.

If you look into the history it is way worse than if it was written by MSFT. The issue with the cec-client is that only piece of software can be controlling CEC at a time and by starting that you take the control away from Kodi.

Apologies, really the correct thread but someone else might find this useful.

I upgraded to a Pi4 and the latest OSMC build. CEC stopped working.
I’ve been here before so tried swapping cables and powering off…
For some reason CEC worked perfectly when I swapped the micro HDMI to the left port. I had it in the right thinking i wanted space between it and the power.

Anyway, left micro HDMI was a winner.
