All audio endpoints are SoundWire peripherals declared under the ACP SoundWire controller: link 0: RT713 (UAJ + SmartMic functions), _ADR 0x000030025D071301 link 1: RT1320 (SmartAmp function), _ADR 0x000131025D132001 With the flag honoured, snd_pci_ps bails out with -ENODEV, the legacy snd_acp_pci driver binds instead and fails with: platform acp_asoc_acp70.0: warning: No matching ASoC machine driver found so no sound card is created at all. Add the machine to acp70_acpi_flag_override_table so that the SoundWire path is used. Tested on LG gram 16Z95U-GS59K (PCI SSID 1854:056c): with this change snd_pci_ps binds and both peripherals enumerate (sdw:0:0:025d:0713:01, sdw:0:1:025d:1320:01).
