As a result snd_pci_ps returns early and the SoundWire links are never scanned, while the legacy snd_acp_pci driver probes the device, finds no matching machine driver ("No matching ASoC machine driver found") and no internal sound card is created. The CS42L45 headset codec on link 0 and the two CS35L63 speaker amplifiers on link 1 never enumerate. Add a DMI entry for the model to the ACP70 ACPI flag override table so the firmware-provided flag is overridden and snd_pci_ps probes instead. Match on the product name rather than the board name, as the same symptom has been reported on several boards of this model (09PVND, 0M0J65, 0C7F12). Tested on a DS14265 (board 09PVND, BIOS 1.5.3) with Debian's 7.2.6 kernel, with and without this entry. With it, snd_pci_ps binds, both SoundWire links come up, the CS42L45 and both CS35L63 enumerate, the existing CS42L45 + 2x CS35L63 machine entry matches, the amplifiers load their firmware and calibration, and the amd-soundwire card plays through both the internal speakers and the headphone jack. Also build-tested on asoc-next with W=1. Developed with AI assistance. Claude read the ACP driver source, identified the BIOS flag as the cause and the override table as the fix, wrote the DMI entry and the out-of-tree test module, and drafted this changelog. All hardware testing was done by the submitter, who has reviewed the change, understands it and takes responsibility for it.
