Title:
HP Probook 450 G8 model T87 support in kernel
Status in linux package in Ubuntu:
Incomplete
Bug description:
[Impact]
The mic mute/audio mute LEDS are not work on HP Probook 450 G8 model T87
[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]
Hewlett-Packard released this year new submodels for some G8 models of
laptops and changed subsystem PCI ID for these new submodels.
HP published special information about this in the next document:
https://support.hp.com/us-en/document/ish_5789324-5789376-16
For example, even HP Probook 450 G8 model listed in
sound/pci/hda/patch_realtek.c, in the laptop with recent T87 submodel audio/mic
mute LEDs not working because of changed subsystem PCI ID.
