I have installed Windows 10 on my Macbook Pro mid-2012 (MacBookPro9,1) using the EFI method. Note: I am intentionally wanting to use Windows 10 in EFI mode instead of the legacy MBR/BIOS method. I used this guide to install Windows 10 using EFI method: https://fgimian.github.io/blog/2016/03/12/installing-windows-10-on-a-mac-without -bootcamp/
Below are the basic specs of my MacbookPro9,1 model:
15inch display with NO Retina
i7-3720QM 2.6GHz with Intel HD 4000 integrated graphics
Nvidia GeForce GT 650M dedicated graphics
8GB RAM
EFI and SMC firmware are updated to latest by installing macOS Sierra
Sep 04, 2018 Intel HD Graphics 4200, 4400 and 4600; Original Graphics kexts in S/L/E; macOS Sierra 10.12.0 or later; Step 1 BIOS Setting: The very first step is to setup your BIOS. This guide will only include settings for Intel HD users. To access your BIOS/UEFI, press and hold Delete key on your Keyboard. The key maybe different in your case. The graphics drivers are built into the Mac operating system; updating to the latest OS release will install the latest drivers. IntelĀ® HD Graphics 4000.
I was able to successfully install Windows 10 using EFI method. After installing Windows 10, I installed the latest v6 of Bootcamp drivers and support software. Everything works except for audio/sound and Intel HD 4000 integrated graphics.
To get the audio/sound working, I tried running the following two files. However, this still didn't fix the issue:
BootCampDriversCirrusCirrusAudioCS4206x64.exe
BootCampDriversCirrusCirrusAudioCS4208x64.exe
Somewhere in the forums, I read that the audio/sound issue is related to integrated graphics drivers for Intel HD 4000. In the Device Manager, I tried to update the drivers for 'Microsoft Basic Display Adapter' by installing Intel HD 4000 graphics drivers using multiple methods below. In all cases, the drivers are detected but while the drivers are being installed, Windows crashes and automatically reboots.

Intel HD 4000 graphics drivers on Intel's Download center website
It would be great if someone can help me get the sound working.
