No, jak jsem pátral, tak jsem zvuk na jacku do sluchátek rozchodil.
Ale nejde dual - čili jack a HDMI do TV současně.
Což dřív šlo.

Viz třeba:

To enable the audio jack on RPi 4B in LibreELEC 10.x you need to:
- edit the /flash/config.txt file ( see https://wiki.libreelec.tv/configuration/config_txt ), use Putty terminal to connect LibreELEC SSH console ( https://www.hostinger.com/tutorials/how-...-putty-ssh ).
- add this line to config.txt: dtparam=audio=on
- reboot LibreELEC
- in Kodi GUI set the Audio output device in Settings - System - Audio menu to ALSA:bcm2835 Headphones, bcm2835 Headphones
