Public bug reported:
The HP EliteBook 6 G1a (SSID 103c:8e0d, SKU Number: AD3Q9ET#UUG) uses a Realtek
ALC236 codec.
Without a quirk no fixup is selected and the mic-mute LED stays off.
It needs the same ALC236_FIXUP_HP_MUTE_LED_MICMUTE_VREF quirk as the
already-supported 14" variant (SSID 103c:8dfb).
I've attached patch that enables mic-mute led with my current kernel
(7.0.0-26-generic)
Patch was built on top of
