[PATCH 0/1] ALSA: hda/conexant: fix FEVM FA880 PRO internal mic mux

From: Ocean Zhou

Date: Sat Feb 14 2026 - 23:46:38 EST


This is a 1-patch series.

On FEVM FA880 PRO with Conexant CX20632, the capture ADC mux on NID 0x14
comes up with conn index 1 (NID 0x1b), which leaves the built-in microphone
muted on cold boot, and it falls back to the same wrong index again after
suspend/resume.

The fix adds an SSID-exact quirk for 2014:8004 and forces
AC_VERB_SET_CONNECT_SEL = 0x03 on NID 0x14 at HDA_FIXUP_ACT_INIT, so the
internal mic path (NID 0x1e) is selected on both boot-time init and resume
re-init.

Tested on real hardware.
