[PATCH] ALSA: hda/realtek: Fix headset mic on ASUS Zenbook 14 UX3402VA

From: George Christidis via B4 Relay

Date: Sun Oct 18 2026 - 12:56:42 EST


From: George Christidis <gxristidis@xxxxxxxxx>

The UX3402VA (1043:16a3) BIOS leaves pin 0x19 unconfigured, so the
headset mic does not work. Use ALC294_FIXUP_ASUS_SPI_HEADSET_MIC like
the UX3405MA, it sets up the mic and keeps the CS35L41 speaker fixup.

Tested on a UX3402VA: headset mic, internal mic and speakers work.
