[PATCH 1/4] ALSA: hda/realtek: Add quirk for Acer Nitro ANV16-42 headset mic

[Zhang Heng]

The Acer Nitro ANV16-42 (subsystem 0x1025:0x1909, Realtek ALC245)
does not detect the headset microphone jack. Adding the
ALC2XX_FIXUP_HEADSET_MIC quirk resolves the issue and restores
proper headset mic functionality.

[PATCH 2/4] ALSA: hda/realtek: Add quirk for Acer Gadget E10 ETBook left speaker

[Zhang Heng]

The Acer Gadget E10 ETBook (subsystem 0x1e50:0x7036, Realtek ALC233)
has a left speaker that does not work by default. The BIOS fails to
properly configure pin 0x1b, leaving it unconnected.

Using hdajackretask to override pin 0x1b as "Internal Speaker"
restores left speaker functionality. Add a quirk to apply this pin
configuration automatically at probe time.

[PATCH 3/4] ALSA: hda/realtek: Fix headset mic on ASUS Vivobook S14 S5406SA

[Zhang Heng]

On the ASUS Vivobook S14 S5406SA (subsystem 0x104310c4, Lunar Lake
platform) with an ALC294 codec, the headset microphone (3.5mm jack)
fails to capture any audio. Adding the ALC2XX_FIXUP_HEADSET_MIC
quirk resolves the issue and restores proper headset mic recording.

[PATCH 4/4] ALSA: hda/conexant: Add pin config quirk for Huawei Matebook

[Zhang Heng]

The headphone jack is not detected on this Huawei Matebook (Conexant
SN6140 codec). The BIOS incorrectly marks Pin 0x18 as [N/A], causing
the driver to report hp_outs=0 and no "Headphones" output appears.

Override the pin configuration for NID 0x18 to set it as a headphone
jack, which restores proper detection and audio routing.
