Title:
Mute/mic LEDs no function on some HP platfroms
Status in OEM Priority Project:
Confirmed
Status in linux package in Ubuntu:
Incomplete
Bug description:
[Impact]
The mic mute/audio mute LEDS are not work on
1) HP ProBook 440 G9 Notebook PC
2) HP ProBook 450 G9 Notebook PC
3) HP EliteBook 640 G9 Notebook PC
4) HP EliteBook 650 G9 Notebook PC
[Fix]
It needs the specific quirk for the hardware layout.
Thus, add the quirks to make it works.
[Test]
After applying the quirk, the audio/mic mute LEDs are working good.
[Where problems could occur]
If HP ships the different system boards design with the same subsystem ID of
audio codec which is using different GPIO pins (different layout), then the
quirk will not work (LEDs will not work when muting audio-output or microphone).
