HDMI audio has been merged into 6.15. Board may need additional device tree nodes to make it work. Analog audio should work already as well bug may also need additional nodes. Collabora sent for Rock5B and 5B+ only upstream. https://gitlab.collabora.com/hardware-enablement/rockchip-3588/notes-for-rockchip-3588/-/blob/main/mainline-status.md

That doesn't work then. The point is to get audio working. We still have a bit of a wait until a proper 6.15 kernel is there.

This should produce an image. That's not needed since it is default anyway.

if NAMESERVER is not set it falls back to default 1.1.1.1 A while ago I made a hack to enforce using whatever hosts nameserver is:https://github.com/armbian/build/blob/e03b1b543cda430fbffcb62c979aecabee42b044/config/templates/config-example.conf.template#L25

hello. Armbian 25.08 for Rockpi 4a executed dtc -O dtb -o rockchip-pwm-gpio.dtbo -b 0 -@ rockchip-pwm-gpio.dts. copied dtbo to /boot/dtb/rockchip/overlays. There is none in /sys/class/pwm/pwmchip1 . /sys/class/pwm/pwmchip0 is available. I can't create the pwmchip1 pwmchip2 folder. Operation not permitted
