Mic mute LED only follows internal rather than selected

alsa-project/alsa-ucm-conf issue #440 was opened from JL2210:

I have a laptop keyboard with a key to mute the microphone. Using this key mutes whichever mic is selected as default. However, the light on the key only changes with the internal microphone rather than the active mic.

Pressing the key when a headset is plugged in doesn't change the LED, but pressing it without a headset does.
