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

From: Zhang Heng

Date: Fri Aug 07 2026 - 08:59:59 EST


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.
