Public bug reported:
When the microphone is muted the light on the keyboard of my Lenovo yoga
7 14akp10 keyboard does not light up. I checked
`/sys/class/leds/platform::micmute/trigger` and it was set to `audio-
micmute` but it does not sink up. I'm still able to manually turn it on
by doing `echo 1 > /sys/class/leds/platform::micmute/brightness`, but it
doesn't automatically sync up.
