Title:
Speaker Mute and Microphone Mute LED indicators not working on HP
Probook 430 G8
Status in linux package in Ubuntu:
Confirmed
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.

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.
