HDMI CEC - RPI4 constantly waking TV

HaCo2013 · January 19, 2024 at 11:26 AM

I stopped using my bluetooth connection and changed to HDMI CEC control.

Everything works fine, except after turning off the TV, 20-30 seconds later, my RPI4 is waking up my TV. I deactivated every setting for turning devices on or off. I only want to control the interface with my remote.

I tried adding some commands to the /flash/cmdline.txt file, but without any changes.
vc4.inval_delay=xxxx (2000-5000) or
vc4.inval_delay=0 vc4.cec_debug=0x100

Rasbperry Pi 4, LE 11.0.3, Samsung TV (2019)

Does someone have any ideas?

Thanks!

I think you need to tell the tv to ignore the pi. I had the same issue and dug around on the tv's setting to stop that. I dont recall off hand where it was in the tv's setting exactly.

Try vc4.force_hotplug=1 in cmdline.txt (on existing line).
