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'

2.) BootCamp drivers downloaded and changed as of 10/23/2019. The modifications are MacHaldriver.sys has been completely removed and through this script installs a MacHaldriver.inf instead to avoid Blue Screen Of Death with Windows 10 ver. 1903 or higher because of incompatibility. Untested on Mid 2011 and Late 2011 Macbooks, please provide feedback if there are any issues. This will be automatically executed when using the script.

3.) Legacy Windows essentials programs will be installed to ease user experience transitioning for Windows 7. Ninite will be executed to insure all users are setup with modern day browsers and including the must have tools to maintain this machine. Anti-Virus will be provided and other useful Microsoft programs including Windows Media Center-Port Over from Windows 7.

I have been working on that problem for quite a while with varied results (though none actually getting the thunderbolt bridge to be recognized) -- the strangest attempt was doing a BIOS install of windows and looking at how it mapped the memory (since thunderbolt works with CSM layer of bootcamp) and creating a DSDT based on those memory ranges; strangely, even without a qword entry, the sound worked but now there were different devices that windows could not allocate into memory -> The HD3000 graphics, a couple of system devices etc.....what I am attempting now is to study the lspci output from linux to see how it maps the devices into memory and perhaps create a dsdt to reflect that ---I am hoping someone in the linux community can teach me how to create a dsdt extrapolated from the ouptut of lspci --- in the hackintosh world we often create a SSDT (secondary system description table) to get thunderbolt working -- but I don't believe Windows can use a modified SSDT -- so maybe we can crack the nut - hoping to do so

Cheers,

Glad we got it all working for ya

Hey buddy some of this is going over my head again, you are clearly incredibly intelligent! Does this help at all? https://www.insanelymac.com/forum/topic/240435-dsdt-using-gfxutil-to-find-pci-locations/ I honestly don't know what I'm looking for to assist you. I hope some of this information from the forum can be some help like how you came across the other forum that gave you the idea of the sound fix.

So what I am pointing out is that linux shows you how they are mapping the devices into memory -- in the same way I used a BIOS install of Windows 10 to make a test DSDT that worked with sound without the same qwords (though there were other problems as stated earlier) I want to make a dsdt that reflects the values of how linux and I presume freebsd etc. allocate devices into memory --

PS. Everybody should have a linux install on their MAC -- it is the swiss army knife and has built-in gdisk to remove hybrid partition schemes which appear to be a big problem with people installing Windows on their Macs in pure EFI (Windows is stupid and requires a pure GPT disk)

Also - Andrew -- you can use the driver manager in Linux to install the Broadcom drivers (as you stated) -- but you can do it even without an ethernet connection -- if you make a linux live USB - those drivers exist on that USB -- and to everybody -- rEFIt -> rEFInd are great products - but I encourage people to learn how to use Macs built in bootloader -- I press alt when I turn on my computer and have custom booter partitions that boot all my OS's ---OSX, Windows 10, Linux, FreeBSD, Haiku, Android, I promise to make a video soon -- will make a short one of my bootloader first -- cause that's easy -- love to all-- goodnight

Of course you could run just live versions...why not have a faster resident version on an internal SSD?

Why not learn how linux works and see the parallels between it and OSX?

For me linux forced me to get my terminal skills better which in turn me more comfortable with the terminal in OSX - the place where you really can do 'power lifting'

Linux also illuminated to me the use of the var, usr, tmp folders which are made hidden in OSX but are still there---again, god forbid one wants to understand how something works and peek behind the 'appliance like' veil that Apple creates

And yes, Windows is stupid in the sense of how it takes that dsdt in firmware as god's word and doesn't allocated devices in the larger 64bit address space available (among other things) -- but that doesn't mean Windows doesn't have a lot of good and useful software ----15 years ago for the bootcamp beta released for OSX Tiger I needed Windows XP to run some VST's that were not available for Mac -- So I installed Windows.......I like a lot of the wifi scanning tools for Windows more then Mac -- so I use Windows --- For the theater company I do IT for I needed a TCP to RS232 forwarder --and there were amazing ones written for Windows so.......

Do I have standalone Windows machines? Of course

Is it it nice to be able to run any software for any OS on the same computer? Yes

could you use VMWare? Yes--- do you have to pay for VMWare? Yes ---Does bare-metal perform better then virtualized solutions? Generally yes

All of the 'contortions' are also an interesting dive into understanding how or why something does or doesn't work --

You, Apple and many others said there was no way to enable sound on pre 2013 Macs--- We found a way --

Is this why you seem particularly salty?

You seem to help many people as you are ubiquitous on these Apple forums --so you should be commended --

but why are you sweating this thread like that?

Hahaha tell'em! I hear the sizzlin burn! OMG I'm LMFAO. He is right Linux is needed, **** have you looked at their Disk Utility tool.... Another great tool - Gparted got it beat by a million. Most of the time the Disk Utility is breaking my partitions. So don't be hater 😉 when we Geeks unite. Apple can go burn itself. As long as they keep ripping people off, the more I will support causes such as this.

Reverse engineering is an art, not science.

The specific implementation of CSM-BIOS and EFI 'hides' devices', not that they are inaccessible. The same devices show using preUEFI in macOS.

Is this why you seem particularly salty?

I assume you understand the Security implications of such changes.
