x86 firmware descriptions are terrible, it's just an endless procession of quirks. The model for ACPI is not to describe key information in the kernel and instead on Windows load device specific information from separately supplied tables. On Linux that translates into these endless quirks, on Windows it's platform specific drivers for otherwise generic audio hardware.
I know all of that, but from the many recent regression reports and patches it seems quirks were not needed for a bunch of Lenovo machines before c008323fe361bd ("ASoC: amd: yc: Fix a non-functional mic on Lenovo 82SJ") [v6.5]. That made me wonder if that commit really did the right thing or if there is a underlying bug somewhere that the newly added quirks hide, as I had a few such situations during the past few months. If you or others the experts in this area say that this is not the case here then I'm totally fine with that, it was just a question.
Until someone tests or otherwise provides specific information on a given machine we're just guessing about how it's wired up.
