If anyone has any objections, please let me know. ------------------ From: Sehat Mahde [ Upstream commit 4d6642d64cd00f276549ec2c0b0278aea2f8c1aa ] The BIOS on the HP OmniBook X Flip 16-cc0xxx (board 8EA2) reports acp-audio-config-flag = FLAG_AMD_LEGACY_ONLY_DMIC. This binds the legacy ACP driver and registers a PDM-only card, so the SoundWire links are never scanned and the two TAS2783 speaker amplifiers and RT712-VB codec do not enumerate. Add a DMI entry for board 8EA2 to the ACP70 ACPI flag override table so the firmware-provided flag is overridden and snd_pci_ps probes instead. On the affected system, an otherwise identical upstream kernel without this entry binds snd_acp_pci, enumerates no SoundWire slave devices and exposes no internal speaker PCM. With the entry added, snd_pci_ps binds, both TAS2783 amplifiers and the RT712-VB enumerate over SoundWire, and the amd-soundwire card exposes the internal speaker playback PCM. Developed with AI assistance. ChatGPT helped analyze the ACP and SoundWire behavior, structure the controlled A/B testing, and draft the patch changelog. All hardware measurements, kernel builds, reboots and playback tests were performed by the submitter. The submitter has reviewed the change, understands it and takes responsibility for it.

Preserve the HP match unchanged so the subsequent Dell quirk has its expected insertion context.
