From d041e5e748f926398ad96436a86667dea8b591e0 Mon Sep 17 00:00:00 2001 From: Ilyas Gasanov Date: Wed, 26 Nov 2025 03:54:41 +0400 Subject: [PATCH] ALSA: hda/realtek: Add quirk for HP ProBook 450 G8 My laptop, HP ProBook 450 G8 (32M40EA), has Realtek ALC236 codec on its integrated sound card, and uses GPIO pins 0x2 and 0x1 for speaker mute and mic mute LEDs correspondingly, as found out by me through hda-verb invocations. This matches the GPIO masks used by the alc236_fixup_hp_gpio_led() function. PCI subsystem vendor and device IDs happen to be 0x103c and 0x8a75, which has not been covered in the ALC2xx driver code yet.
