From d395e1b62d9694f2e4add9122f8d473eacd374aa Mon Sep 17 00:00:00 2001 From: Daniel Ortiz Date: Sat, 19 Sep 2026 20:19:20 -0500 Subject: [PATCH] ASoC: amd: yc: Add DMI quirk for Lenovo V15 G6 ARP The Lenovo V15 G6 ARP (product name 83UU) uses the ACP6x PDM interface for its internal digital microphone array. Its firmware exposes neither the AcpDmicConnected _DSD property nor the _WOV method, so acp6x_probe() falls through to the DMI check and returns -ENODEV, leaving acp_yc_mach.0 unbound and no capture device registered. Add a DMI quirk entry for this model. With it, the machine driver binds and the DMIC capture device is created: acp_yc_mach acp_yc_mach.0: Enabling ACP DMIC support via DMI card 2: acp6x [acp6x], device 0: DMIC capture dmic-hifi-0 Capture was verified working with arecord and PipeWire.
