MBP UEFI WINDOWS SOUND FIXED!!!!

Hiya

I've successfully done this mod to get audio on my mid 2011 iMac. I would be interested in a automated process script or a video if one is available though. Didnt mind going through the process to do the mod, but i've created a backup of my windows installation so I don't have to in future. But would still be handy to have a script for all or part of the process. Many thanks.

Hey Markgreatrex,

The best news at the moment is that script is almost done! The script is geared to to early 2011 MacBook Pros, I have no way of testing the script without being other models. Currently I'm stuck to where I can't get past two command lines to fully finish the project. Bcdedit /set testsigning on and asl.exe /loadtable dsdt.aml will not run correctly in .cmds or .bats, without opening cmd as admin and put it these commands to work.

So far so good, now I'm trying to get past being stuck only on the asl.exe /loadtable DSDT.aml - The command works manually but trying to automate this has been a challenge. I'm trying to make a .bat file or .cmd file to run this correctly but no luck. I'm literally 99.9% percent done. Once I can get past this, this will be uploaded on github, alternative.to, howeitworks.com, and google drive. I'll post all links once done. ANY HELP IS APPRECIATED!

I wish I could help out, but it's beyond my skillset. If there's anything else I might be able to help with it even to give a second opinion, my emai is markheiron@yahoo.co.uk. I'm currently trying to write up the documentation for setting up my mac, there were a few things I had to fix at installation and it's hard to remember it all. I'm just really glad to have got the sound working on my mac without having to run through bootcamp. Wish I had done it years ago. I will keep an eye out for the links though. Thanks again for your work!

Its all good, I figured it out, I'm going to be in testing stage tonight, Trying different version of Windows, different usernames to make sure Valor (The Script's Name) holds up. I've added BSOD fix, free cloud anti-virus that doesn't run in the background, other IT tools to keep track of the Mac's health. I've added some personal touches to express why this project is made and I've merged the old drivers and the new drivers together to make the bootcamp software work. This is going to be live hopefully in the next day or two.

We all should be saying thank you to you! You are awesome and without your methods there would be no patch! There would be no script and most of all there would be no community to aid your cause. So THANK YOU sincerely for your efforts and sticking with this before any of us came along. I had given up back in 2017 on the UEFI audio issues until I accidentally stumbled across your forum. Happy thanksgiving or happy holiday to you my friend, please let me know if there is anything else I can do to help. You have my email hmu anytime.

Hello AMcomputers I see that you are having an issue, good news I have a script called Valor that can automatically patch your audio issues and get your drivers working. Please check out http://www.howeitworks.com/valor and its tutorial videos to learn how to install and deploy the script. If you get stuck please let me know, I just released an update on Thanksgiving. Remember Valor Lite is pretty much the script so use this if you want just the patch, if you want more exclusive content use Valor AIO. I apologize for the late response I've been sick as a dog, I'll get back to you as soon as I can, I start back to work tomorrow working 11 hour shifts until this coming Monday.

Hello KyuR_pt, please look at www.howeitworks.com/valor to see methods and videos both from TGIK and itayemi. Download Valor Lite to access content if not Valor AIO use zip or iso downloads. Tutorial videos, written text files for breakdown is in archives of Valor. Tutorial videos for Valor are on my website.

Yes actually use the .iso instead so that windows will mount it and then click on Valor_Lite_Start and it will copy over the directories exactly the way it needs to be. If the folder and sub folders are not setup right the script won't work. So use the iso file and double click to mount it and then you will see it under "This PC" until ejected or when you reboot your computer.

I'm on a 2012 MBP and already have an external drive UEFI Windows 10 boot largely working, except for built in sound over headphones and speakers. (External sound over HDMI works great with the NVIDIA drivers.) I'm not sure how I originally set this up (it's been a while) but I'm pretty sure I didn't use Clover. I've got a partition with an EFI folder on it, and I'll try the registry mod method, but it sounds like there are potential performance issues. In reading through the linked guides, I've come across the automate-eGPU EFI method, but can't find a standalone installer whose version matches that in the article. The old one (1.0.4) fails on install asking me to upgrade to High Sierra...but I'm on Mojave. The terminal string provided in the 1.0.5 instructions doesn't work. I tried manually copying the EFI folder onto my EFI volume and I get to a bootloader, but it doesn't seem to actually work to boot Windows. Any guidance you can provide is greatly appreciated (and not in the slightest bit time critical, this is a hobby machine.)

This is what I use, it works for Windows EFI and Windows Legacy.... Hopefully this works for ya. I want to do a stand alone video but I need hardware to pull it off and I just don't have the resources to do so.... I'm sorry for the late response, I work for Amazon currently and OMG 10-12 hour shifts with Mandatory Over Time has been kicking my rear end. https://www.rodsbooks.com/refind/installing.html if need more info let me know I'll try to get back to you as soon as I can!

Hey my pleasure I'm glad it worked out! The big thanks goes to TGIK and itayemi because the project would have never happened if they never came out with there methods, all I did was script it together and did some mods. I appreciate it though! Happy New Years!

We're now in 2020 and I still need help with this. (~_*). Happy New Year guys.

I would have downloaded xAndrewH1993x's patch, but he constantly reminds us that his patch is for MBP 2011 and I fear "bricking" my machine.

My machine is a Mid 2012 MBP. I have installed EFI windows and I have been without sound. I was reading till the end of the thread to see if TGIK's video was linked somewhere. Seems he dumped it eventually once xAndrewH1993x finalized his process. I also tried itayemi's link but the link is now broken.

I'll appreciate any help I can get. I'm a noob at this but surely love to experiment. I'm open to a zoom walkthrough or to an upgrade in xAndrewH1993x's patch that will accommodate Mid 2012 MBP, or to a step by step from any of your geniuses in the house.

Thanks in advance.

Hey Spirit hope you're doing well so I just so happened to see your post in my email and I'm going to clear some things up. See everything is in Valor so itayemi methods is literally copied and pasted into a text file that is located within the patch so you just have to look for it in the file once you download Valor. Next thing I want to make it clear to everyone that there is no way to possiblely brick your MacBook using Valor. The only way you're going to break/brick your MacBook is if you're installing and manipulating the bootloader itself and even then that's pretty much like heavy stuff. All you need to do is just run Valor and if it doesn't work then reinstall Windows. This is supporting the latest Windows 10 ISO release from Microsoft. Please if you have any other questions fill free to reach out to me directly if you have questions about valor's compatibility. I have made it clear that if somebody is using Valor on Windows that is not meant for the 2011 MacBook pro they can risk breaking Windows itself causing you to have a blue screen so make sure you do a system restore point and try it and if it fails... restore from the last system restore point through windows recovery and if that doesn't reinstall Windows 10. Restore point help link: https://www.windowscentral.com/how-use-system-restore-windows-10 I put a disclaimer on my website and on forums to protect myself. However after multi users testing I've seen compatibility on 2012s.
