[x86-64] CEC broke after updating to LE 12.2.0

Same here!

Lg tv (hdmi2 arc) -- ( hdmi out arc)lg soundbar (hdmi in) -- pulse eight hdmi cec -- intel nuc

the cec config resets it self always, how can we install the old 4.0.7 over the 7.1.1 in libreelec 12.2.1???

Me too. RPi4B and LG C3 OLED 2023. CEC worked for the longest time and then it just stopped working. I've tried everything I found in any thread on the internet (including deleting cec_CEC_Adapter.xml), but no luck at all.
