Audio driver not working

Hello,

After installing Windows 10 20H2 on my Mid-2012 15" MacBook Pro, I still can't get the audio (speakers and microphone) working, even after trying to install the version 6.1 and 6.2 support software. Everything else, such as the camera, seems to work fine (except for an issue where I get a BSOD when updating the graphics drivers through Windows Update, but for now I disabled updates).

This is a fresh install (the second time) and my MacOS version is 10.15.7 Catalina.

I tried manually installing the drivers from the Cirrus folder, but no luck... I simply get the error that the "best driver (the default Microsoft one) is already installed." Neither .inf files I extracted from the Cirrus installers seemed to work when manually "updating" the drivers.

I suspect this is because the Cirrus driver I'm trying to install comes is from circa 2015-2016, but the default Microsoft driver is from 2019, but my MacBook Air, for example (same version of Windows), is doing fine with audio.

I tried removing all files associated with the default Microsoft audio driver, but when I remove the "High-Definition Audio" device(s) from device manager (as I've already tried several times), after restarting or refreshing devices, they just come back, still trying to use the Microsoft driver.

Any tips on how I can get the audio working, like for example, force-installing the driver? I honestly don't care whichever driver may end up working, but it seems like the Microsoft one is not working at all (failed to start service, if I remember the error from Device Manager correctly).

Neither Apple or Microsoft were able to figure any kind of solution out, so those are not options.

Thanks!
