If anyone has any objections, please let me know. ------------------ From: Jetha Chan [ Upstream commit e782d687d2f5bf8b8113dc48ba22cca4b472c252 ] The Alienware m15 R7 AMD exposes an ACP6x DMIC path, but its DMI product name is not present in the Yellow Carp ACP quirk table. As a result, the ACP machine driver does not enable the DMIC card on this system. Add the DMI product name for this machine. With this quirk applied, the kernel reports: acp_yc_mach acp_yc_mach.0: Enabling ACP DMIC support via DMI and ALSA exposes the ACP DMIC capture device: card 3: acp6x device 0: DMIC capture dmic-hifi-0 Tested on an Alienware m15 R7 AMD with product SKU 0B59.
