Subject: [PATCH] ALSA: hda/realtek: Add headset jack quirk for Thinkpad X390
Date: Sat, 7 Mar 2026 06:29:06 +0500 [thread overview]
Message-ID: <20260307012906.20093-1-contact@uzair.is-a.dev> (raw)
The Lenovo ThinkPad X390 (ALC257 codec, subsystem ID 0x17aa2288)
does not report headset button press events. Headphone insertion is
detected (SW_HEADPHONE_INSERT), but pressing the inline microphone
button on a headset produces no input events.
Add a SND_PCI_QUIRK entry that maps this subsystem ID to
ALC285_FIXUP_THINKPAD_NO_BASS_SPK_HEADSET_JACK, which enables
headset jack button detection through alc_fixup_headset_jack()
and ThinkPad ACPI integration. This is the same fixup used by
similar ThinkPad models (P1 Gen 3, X1 Extreme Gen 3).
