With the H618 kernel, the system is very stable but there is no audio output at all.
With the H616 kernel, audio works perfectly, but the system starts showing screen distortions, artifacts, and UI crashes. When I said “image became distorted” and “kernel artifacts”, I meant things like the screen going black, color blocks appearing, and the desktop environment crashing.
I already tried enabling analog-codec, installing alsa-utils, using alsamixer, and testing with mpg123, but the result didn’t change.
I haven’t built my own Armbian image yet, but I’m considering trying an edge kernel with the Armbian build system.
