MBP UEFI WINDOWS SOUND FIXED!!!!

If anyone is still interested I have found the solution for audio on MBP 2011 Windows 10 UEFI installs - it has taken me 4 years to figure out. I was given the answer from a tutorial only adjacently related -here:

https://egpu.io/forums/pc-setup/fix-dsdt-override-to-correct-error-12/

essentially what we knew was that windows didn't 'see' the correct audio devices when booted in pure efi-

The part that was frustrating to me was that many users like myself have lots of UEFI installs on their 2011 MBP and those OS's have no problem 'seeing' the HD audio controller -

So what was windows doing different?

I had messed around with mm commands in a UEFI shell (The shell provided in the rEFIt package) to no avail*

I had tried to pass SETPCI commands from grub into Windows 10- no luck*

A quote from the link above got my brain spinning

"A Windows system's DSDT table root bridge definition (ACPI PNP0A08 or PNP0A03) is usually confined to a reserved 32-bit space (under 4GB) budgeted to be large enough to host the notebook's PCIe devices. A watermark TOLUD value is then set and locked in the system firmware. Windows OS honors the root bridge definition and will allocate PCIe devices within it. macOS ignores the root bridge constraints as too does Linux when booted with the 'pci=noCRS' parameter. Neither of those OS require a DSDT override and can allocate freely in the huge 64-bit PCIe address space"

So Windows 'honors' the root bridge and OSX and linux disregard it --hmmm interesting.

As someone who also deals in hackintoshes I am very aware of DSDT's and how editing them can help get OSX running on home brew PC hardware- I had played around with installing Clover (the UEFI bootloader almost synonymous with Hackintoshes) on USB thumb drives and putting the DSDT from my MBP 2011 in the /Clover/ACPI/Windows folder - still nothing-- I thought that pointing windows to a DSDT would be enough.......

A side note is that there are people who have 'bricked' their real Macs when using clover, I have never had that issue personally (a sub-link in the link above describes such a situation)*

If you follow the guide and make a modified DSDT (one that add 'qwords' to the dwords section) you can test it in two ways-

I used Maciasl to extract and edit my DSDT to add a 'Qword' section - I placed the DSDT in two locations /EFI/Clover/ACPI/Patched [not sure if that one matters] & /EFI/Clover/ACPI/Windows

holding ALT/option during bootup I selected "EFI Boot" from the USB clover and booted into Clover

for the exact Clover configuration send me a message

After booting into windows the sound card was immediately working (this was because I had installed the cirrus logic drivers from bootcamp 4) - the display audio driver in device manager had an exclamation point but I was able to install the display audio driver from intel's driver support for the i7 2470m CPU in this machine-

I also looked at device manager via 'by resources' and saw that a new entry 'Large memory with an address range appeared

And low and behold the address range for the 'large memory section' contained the range for the hd audio controller

I then wanted to see if the method described in the initial link posted above where you force that memory map into the registry and turn on 'test signing' worked --

it did, which allowed me to boot directly into windows without the help of clover --

*NOTE: when I tested the registry method I skipped the first few steps since I already had a modified DSDT- I did need to create the 'C:\dsdt folder and extract the windows binaries to that folder - but I did not use their acpi dump nor compiler (I check for errors and compiled my dsdt in Maciasl in OSX)

I would gladly go more in depth but I doubt there are many more who need this information- just glad to have figured it out without the BIOS emulation of bootcamp- going to test this method on other 'pre 2013' Macs with non complient UEFI bios'

Hi, wouldn't it make more sense to disable the Intel HD3000 GPU in EFI if this is possible? instead of the AMD . Because the AMD GPU is not broken and has the better performance I guess. But I just found articles about disabling the AMD GPU instead of the intel GPU. Everyone is disabling the ADM GPU, I guess because of the issue that it breaks at some time.

BTW to disable the Intel HD3000 GPU in device Manager prevent the system to get the Bluescreens. But I still couldn't install the AMD Driver correctly. So it seems without the working AMD or Intel Driver the Graphic is working but not in the full acceleration. Videos don't play smooth.

@xAndrewH1993x in Valor light I found a small issue.

In the File: "Valor (DOUBLE-CLICK-TO-START)" and iaStorA_Installer.bat (Valor_Lite-(Dont-Delete-Backup)\Resources\Drivers\Pre_Downloaded\BootCamp\Drivers\Apple\iaStorA)

@echo iaStorA (IDE ATA ATAPI Drivers Update (BSOD FIX) Installer

chdir %SYSTEMDRIVE%\Users\%USERNAME%\Downloads\Valor-(Dont-Delete-Backup)\Resources\Drivers\Pre_Downloaded\BootCamp\Drivers\Apple\iaStorA

start README2.txt

call iaStorA_Installer.bat



@echo iaStorA Installer

start "" "%SYSTEMDRIVE%\Users\%USERNAME%\Downloads\Valor-(Dont-Delete-Backup)\Resources\Drivers\Pre_Downloaded\BootCamp\Drivers\Apple\iaStorA\dpinst.exe" /a /path %SYSTEMDRIVE%\Users\%USERNAME%\Downloads\Valor-(Dont-Delete-Backup)\Resources\Drivers\Pre_Downloaded\BootCamp\Drivers\Apple\iaStorA\

Pause:

should be: Valor_Lite-(Dont-Delete-Backup) instead of Valor-(Dont-Delete-Backup)

Thank you I'll fix it first thing in the morning and re-upload. Hope you have a good night! I apologize for the reason to support 2012 models. It is because I'm limited to early 2011 hardware and don't have 2012 models to build Valor on.

My response was pointed to a poster who had a broken AMD gpu - which clearly seems to be a pretty common issue with these macbook's. I am sure there is a way to also do it for the HD3000 but as you found there isn't much documentation on it -- It needs to be done on either the EFI firmware level or perhaps I need to look at my original DSDT edits and see if I can make the device invisible via the DSDT -

I appreciate the work you guys did to figure this out.

I sskimmed the thread, I saw a lot of mention of 2011 mbp and 2012 mbp, I have 2012 macbook air, any advice on that? If there's any chance of brick no way though, I already have a windows laptop but I prefer the small form factor of this macbook.

What I did, was use aomei backupper to clone a system drive of a windows 10 version 1909 pro laptop with all my stuff. to an external ssd, option key boat, I load efi, it works, all my apps, it's exact clone, then I installed bootcamp drivers.

but no sound (High Definition Audio Controller, error 10), can't install Intel HD Graphics 4000 (I had to block it) or it will crash my drive, my device manager shows Microsoft Basic Display Adapter, it works and looks ok, but I can't adjust brightness.

Is there an easy fix, with valor or some other means? I can email with someone if they are nice enough to help me through some quick steps.

I have a macbook air 2012, going to try itayemi's method, but even if my audio is fixed, my intel graphics driver won't be able to be loaded without crashing, and I won't adjust brightness, will valor allow this to be done on 2004?

thanks for reply, I downloaded them all, took a long time, my windows is 1909 still, going to update to 2004 first (should I?) as well, my windows is run off an external cloned ssd drive, no connection to bootcamp really other than I installed the drivers, no bootcamp partition, will valor aio or itayemi apply to a setup like mine?

hey I'm done with all this efi broken windows stuff, I just want to be sure, can I install legacy bios windows from bootcamp assistant running gpt guid apfs catalina 10.5.7, doing it all from the same internal drive? Is there a risk of messing up my mac partition? 2012 macbook air.

TGIK this is xAndrewH1993x, I changed my Apple ID and information over. Now my biggest question to you @TGIK if you can join this community: https://discord.gg/XbbWAsE and see if we can work together to finding a solution for Macs that is not Metal to work with OpenGL. Is that something that you are willing to do? Big Sur is dirt slow on my Macbook Pro 8,1. They created patches and keep up to date with development for unsupported macs. I had emailed you earlier about this but never got a response so I assumed that you were busy and missed my email. I think most of us are not ready to upgrade our Macs to newer Macs that are not upgradable. I hit up ASentientBot to try to find a solution to this issue, but he has not been able to find a solution and this like he did with Catalina and Mojave. He is needing some help.

Hey man, the ask for the info. I’m really quite useless with all of this, I need windows on my mid 2012 MBP. I managed to install etc only to be met with no sound (surprise surprise). Anyway I don’t have a clue about the files and binaries etc I tried to understand from your post, it’s my lack of knowledge not your explanation. Haha, but please, for dummies, how can I get sound through my windows 10 on my MBP? It’s to run a copy of some music production software as the one I have for Mac doesn’t work.

thanks man,

E.

Thanks Howeitworks! Thats has been the most helpful thread I have encountered in regards to dual booting my MBP 2012. I joined your discord server as well!! Glad to find community amongst the neo modern drab of the Apple Support forum!

I'm going to backup my OS's and test the patches sometime this weekend. I'll keep you posted!

Nice, sounds good if you need anything hmu on Discord or on here in case I don't get back to you on Discord. Good luck! I'm going to be reformatting here soon too, I'm planning on getting a 2TB SSD for $189 bucks from BestBuy, also since you have a 2012 Mac, your Mac could potentially work with Hardware Acceleration for Big Sur. If you need a guide on how to create a usb installer for Big Sur with the patches on Windows, please let me know as I have a video on that with the available download link for MacOS Big Sur through a bootable bin file. Bensova and BarryKN are active a great help as well!

I already have a fully working Windows 10 install in Legacy Mode on a MacBook Pro mid 2012 (non-retina). I haven't really encountered any problems in using an hybrid MBR along the years, but I'd like to change my install to an UEFI one mainly because I want Windows to be able to see more than the first four primary partitions of the disk. (MBR limitation)

Sound was an issue, but now I see this is an easy fix with the method described here, thank you all!

it appears that at least on the 2012 models thunderbolt appears to work -- seeing if one on ebay falls in price to be my test dummy

Can someone confirm that? If I can't use thunderbolt I will stay in Legacy Mode because this is a must for me. Other than that, are there any other downfalls of using UEFI (knowing that it is technically unsupported) instead of Legacy Mode on pre-UEFI macs?

Thank you again!
