snd-rn-pci-acp3x - auto dmic detection unreliable
Hi,
it seems that the ACPI auto-detection of the presence the digital microphone connected to AMD Renoir audio bridge is unreliable. It may be that hardware vendors do not provide the correct ACPI tables. Could you clarify the usage of _WOV integer value? It seems that this value is set on those plaforms which do not have the digital microphone (the microphone is connected to the HDA codec):
Lenovo IdeaPad 5 (15ARE05) Lenovo Thinkpad X395
In any case, we should probably improve the auto-detection using DMI or other platform info.

_WOV integer value should be set only when DMIC is connected to APU. When DMIC is not available, _WOV integer value should be set to zero by BIOS.

We are already provided reply on 18th Nov.
_WOV integer value should be set only when DMIC is connected to APU. When DMIC is not connected to APU, _WOV integer value should be set to zero by BIOS.
DMIC doesn't had auto presence detect logic on AMD platforms and DMIC connection to AMD platform is simple wiring. Whether DMIC connected to APU or HDAUDIO codec can be decided by ODMs.
ODM BIOS has update the _WOV method value based on DMIC connected to APU or not.

Thank you. Please, format correctly your e-mail messages, do not write your answers inside the old text without '>' markers:

I just overlooked your lines inside my forwarded message.
So the problem is that the hardware vendors do not do the right job in this case.
Thank you again, Jaroslav

Sorry it's my bad. Due to limited access to my linux machine, Last time I have replied from Outlook server instead of thunder bird mail client which resulted format related issues.
