HDMI CEC stopped working after Matrix update on the RasPi 3 B

Help and Support

I’ve been running OSMC on my Raspberry Pi 3 model B rev 1.2 for over a year now.
HDMI CEC always worked out of the box on the two LG TVs I’ve ever had.

Now, after the update to Kodi 19 Matrix, CEC stopped working right away. Any idea what should I do?

Here is the output of cat ~/.kodi/userdata/guisettings.xml ~/.kodi/userdata/peripheral_data/rpi*.xml

Side note: dispmanx_vncserver stopped working as well even after full uninstall and reinstall, but I understand I shall ask about it on the existing VNC topic, or create a new one…

With cec problems the first thing to try is completely powering down the tv and the pi for a minute or so and retry

VNC would only work with the fkms driver which is not recommended to be used.

OMFG I’ve done it separately a few times since I’ve updated last week, and no difference. But now, I’ve removed the Pi, the TV AND all other peripherals connected to them from the power grid, and voila!

Thank you for the insight!

Hmmmm

Then CEC stops working again :sweat_smile: :cry:

And shutting everything down doesn’t fix it this time… Guess VNC is a no go from now on (or at least until someone finds another way)

CEC is a 1 wire bus.

Another device connected to the TV may be causing this issue.
