Subject: [PATCH] ASoC: amd: yc: Add DMI quirk for HP Laptop 15-fc0251la
Date: Wed, 04 Mar 2026 15:44:50 -0300 [thread overview]
Message-ID: <2635256.2bixRq88gB@goku> (raw)
The HP Laptop 15-fc0251la (B9TP2LA) has an internal DMIC that
is not detected without a DMI quirk entry, as the last BIOS
(ver F.21) does not set the AcpDmicConnected ACPI _DSD property.
Adding the DMI entry enables the ACP6x DMIC machine driver to probe
successfully.
