From 11bdeb33df051f4c3a8504d78e113e1127f97b63 Mon Sep 17 00:00:00 2001 From: Zhang Heng Date: Sat, 17 Oct 2026 17:54:00 +0800 Subject: [PATCH] ALSA: hda/realtek: Add fixup for Huawei MateBook X Pro 2019 (MACHR-WX9) On the MACHR-WX9 (ALC256, PCI SSID 19e5:3e13) the BIOS pin table disables the main speaker pair (pin 0x14), so only the tweeters on 0x1b play. Reusing the MACH_WX9 (19e5:3204) pin table restores all four speakers. Pin 0x19 (headset mic) has broken presence detect on this board: it reports "plugged" even with the jack empty, so auto-mic routes capture to the empty jack and the internal mic goes silent. Setting NO_PRESENCE on 0x19 (0x04a11140) suppresses the false reading. Chaining to ALC269_FIXUP_HEADSET_MODE then infers headset-mic presence from the headphone jack (pin 0x21), whose detection works correctly. Add ALC256_FIXUP_HUAWEI_MACHR_WX9_PINS with the MACH_WX9 pin table, chained to ALC269_FIXUP_HEADSET_MODE, registered for PCI SSID 19e5:3e13.
