[PATCH] ASoC: amd: acp: Add DMI quirk for Lenovo Legion 7 15ASH11

From: Jackie Dong

Date: Mon Jul 27 2026 - 00:19:03 EST


Lenovo Legion 7 15ASH11 with AMD RYZEN AI MAX+ 392 (Strix Halo, ACP
7.0) uses Realtek ALC287 series codec and no any DMIC connected by ACP.
All DMICs directly connet with ALC codec.

Without this quirk, Input Device of Gnome Sound settings shows Internal
Stereo Microphone and Digital Microphone by default. In fact, Digital
Microphone of ACP doesn't work due to no connecting with ALC287 codec,
the Internal Stereo Microphone as analog device based on snd_hda_intel
driver can work well.

Add a DMI quirk to override the flag to 0, consistent with the existing
entry for the Lenovo Yoga Pro 7 15ASH11.
