From d830631a128b394793811d9de61550d4518906cd Mon Sep 17 00:00:00 2001 From: Naser Al-Asbahi Date: Sat, 25 Apr 2026 17:40:14 +0200 Subject: [PATCH] ALSA: hda/realtek: Add micmute LED quirk for Acer Aspire A315-44P The mic-mute LED on the Acer Aspire A315-44P (subsystem ID 0x10251640) does not light up when the microphone is muted. The LED is connected to GPIO3 of the Realtek ALC256 codec. Add a quirk entry using ALC256_FIXUP_ACER_SFG16_MICMUTE_LED, which configures GPIO3 (bitmask 0x04) as the micmute LED, identical to the Acer Swift SFG16. Tested by manually sending HDA verb commands directly to the codec and verifying that GPIO3 drives the LED while GPIO1 and GPIO2 do not.
