It looks like acpiasus only matches the older ASUS hotkey IDs such as
ATK0100 and ATK0101, and does not attach to ATK3001. acpiwmi does not
attach to the PNP0C14 WMI mapper devices on this
machine. The result is that no driver is delivering the brightness and
volume hotkey notifications to the kernel.
Backlight control itself works fine through wsconsctl
display.brightness, and audio works through sndioctl, so the hardware
is fully controllable. The only thing missing is the hotkey
delivery.
I would like to ask whether there is any planned or in-progress support
for ATK3001 or the newer ASUS WMI hotkey interface, or whether there is
a way to attach these devices so the keys
generate events. I am happy to test patches and to provide any
additional ACPI dumps, such as acpidump or the DSDT, on request.
I have exactly the same laptop model. If I remember correctly acpiwmi is
not enabled for GENERIC kernel. If I compile a kernel with it I can
control volume keys and keyboard backlight keys.
For me a bigger problem is GPU not initializing correctly from time to
time. I see in your dmesg you have the same problem.
