Sound not working in Windows 10 (MacBook Pro mid 2012)
Hello.
I wanted to do a clean wipe of my MacBook Pro mid 2012 so I reinstalled macOS and upgraded to Mojave then reinstalled Windows.
Now, unfortunately, I had two issues:
First, my laptop was crashing with KERNEL SECURITY CHECK FAILURE. I followed this thread (https://discussions.apple.com/thread/251094222) where I renamed both AppleHFS.sys and AppleMNT.sys to sys.bak, which solved the BSOD problem.
Now, I am stuck on the second issue, which is that the sound is not working.
I tried:
- Resetting NVRAM
- Resetting SMC
- Reinstalling Boot Camp drivers from files downloaded by the BC Assistant in macOS.
None has worked. However, I have noticed that when during the multiple times when I installed the Boot Camp drivers, my speaker icon flashed for a fraction of a second with the levels (three curved lines) indicating that my sound drivers were installed. However, for some reason, it was only a flash and icon went back to a red circle indicating that there are no drivers. Additionally, when I shutdown my Windows, and in the few seconds before the screen goes dark, the speaker icon also flashes with the curved lines indicating that my sound is working. Those are the only two instances where I see my sound working.
I really hope that there could be a solution to this. And I am also quite perplexed as to why my Windows Boot Camp was working just fine on the same version of macOS just a week ago and now after this reinstall everything broke... Was there something with my reinstallation process of macOS that messed things up? Should I choose a different File System (since HFS seemed to have been causing the BSOD problem)? Or is there anything I can do so that I can go back to a regularly functioning Windows Boot Camp partition?
Best Regards.
Windows, Windows 10
