Hey there thanks for that quick answer!

I have to admit that im kind of a newbie and didnt dwell too deep into the topics of a linux operating system. As i understand your post, youre saying that the focus of the libeElec distro is to make the audio output work for hdmi but the underlying system might not be supporting (/having any drivers) for the hardware audio chip/device responsible for the 3.5mm output of my sbc, am i right?

What made me curious was the fact that 'ES3816 Analog Audio' is an option to choose from in the dropdown menu and therefore i thought that those drivers are existing.

Sorry for being kind of a newbie and maybe asking dumb questions, but could explain to me how i can check for that you asked me for? (sorry for my bad english its not my first language) If that would be too time consuming for you, you can also point me to some ressources i could go through to get a better understanding of the topic, thanks in advance!
