Create file /etc/udev/hwdb.d/61-keyboard-local.hwdb with the content

evdev:atkbd:dmi:bvn*:bvr*:bd*:svnAcer*:pnNitroAN515-47:pvr*
 KEYBOARD_KEY_66=micmute                                # Microphone mute button

then run

systemd-hwdb update
udevadm trigger /dev/input/event*

Key should now be recognized as mic key. If not, try rebooting.

¡It does works, thanks! LED is not working though (of course), it’s still turned off when either mic is on or off.

OK, if you feel adventurous, you could submit PR for systemd. It already has definition of scancode 66 for another Acer model, so it is really one-liner (OK, one and a half including comment), no programming skills needed:

Otherwise consider at least opening issue on systemd github.

ls -l /sys/class/leds/

I’ll do it later

It doesn’t seems to find the microphone LED
