There is /sys/class/leds/platform::micmute from asus-nb-wmi, but snd_ctl_led isn't loaded.
Microphone isn't connected to acp, so snd_rn_pci_acp3x isn't getting loaded.
I can get led switching working if I attach 'Capture Switch'
modprobe snd_ctl_led
echo 'Capture Switch' > /sys/class/sound/ctl-led/mic/card1/attach

For standard HDA hardware, audio LED triggers are activated only for specific models using quirks. It's not a job for UCM at the moment. You may discuss this in linux-sound@vger.kernel.org mailing list.
