CEC PI4 not off

1st Official Post

    Hi guy, when i switch off my TV the PI4 not shut down.

    I have the lastest distribution off librelec and, kodi 18.8 a Argon One for PI4 case.

    Before i had a xbian distribution (with no case) on a PI3, kodi 18.4 and when i shutdowns TV, the PI3 shut down too (CEC command i think ...)

    Some of your have some informations ? Do i have to adjust CEC comportement somewhere in librelec (i search everywhere but i don't find)..

    Thanks you for advice
