On my NanoPi R6C I downloaded the Armbian 23.11 Bookworm CLI and booted the machine from the SD card. Then I installed gnome and firefox. Most things works so far, but I get no sound over hdmi (there is no headphone jack). The gnome - settings - sound shows only the dummy device. Youtube videos play ok, but somewhat laggy and with very high processor load (all cores close to 100% on the gnome system monitor).

I bet you saw a big warning when you boot this image for the first time? Warning is there, because its impossible to help.

 

Use kernel 5.10.y for better hardware support. Many functions on mainline are not even developed yet.

Ok, so I downloaded the Armbian Jammy-amazingfated with Kernel 5.10, where everything works out of the box. Youtube Videos require processor loads < 40%.
