Bug Description
The HP ProBook 430 G8 has LED indicators built into the F6 key and F8 key to indicate that the Speakers (F6) and Microphone (F8) are muted. Pressing F6 correctly toggles the output of sound off and on, but the indicator LED never illuminates. Pressing F8 correctly toggles the Microphone input on and off, but again the indicator LED never illuminates.
The expected operation would be that each of the LEDs would be illuminated when their respective mutes are in effect.

Kernel driver in use: sof-audio-
Kernel modules: snd_hda_intel, snd_sof_
Using:
sudo hda-verb <device> 0x01 SET_GPIO_MASK <bitposition>
sudo hda-verb <device> 0x01 SET_GPIO_DIRECTION <bitposition>
sudo hda-verb <device> 0x01 SET_GPIO_DATA <bitposition>
... with /dev/snd/hwC0D0 as the <device> and <bitposition> set to 0x01, 0x02 in turn it is possible to see that the F8 (Mic Mute) LED is connected to the GPIO associated with <bitposition> = 0x01, and the F6 (Speaker Mute) LED is connected to the GPIO associated with <bitposition> = 0x02.
Code appears to exist to drive these LEDs (and is used by other HP ProBook models) but it needs to be enabled when this specific Audio Controller [103c:87df] is detected.
