No Audio ( Bootcamp )

Good night, I performed the entire procedure described in the order, however, has some observations.

1 - I did not need to make the TM , as the HD I have in the MAC , is just to use Mac and Win. then I had nothing to back up .

2 - to make the recovery using the internet , it downloads the Lion Recovery , so far so good , time to start installing the system , it asks for my login and password of apple , typing correctly, a warning appears that tells the Lion is not available at this time. I can not install the system .

3 - I'm trying to download the yousemite , create a bootable disk and try for it. however, you will not be using mo recovery mode the internet.

I'll try a few more times , and answer so get news .

Thanks!

Boa noite, executei todo o procedimento na ordem descrita, porem, tem umas observações.

1 - não precisei efetuar o TM, já que o HD que tenho no MAC, é justamente para usar MAC e Win. então não tinha nada para se fazer backup.

2 - ao fazer o recovery usando a internet, ele faz o download do Lion Recovery, até ai tudo bem, na hora de começar a instalação do sistema, ele pede meu login e senha da apple, ao digitar corretamente, aparece um aviso que informa que o Lion não está disponivel no momento. Não consigo instalar o sistema.

3 - Estou tentando baixar o yousemite, criar um disco bootavel e tentar por ele. porem, não vai ser usando mo modo recovery da internet.

Vou tentar mais algumas vezes, e respondo assim que obtiver noticias.

Muito obrigado!

If you have purchased Yosemite from the Apple App Store, you can download the Yosemite installer again directly and install it, instead of running Lion via Internet Recovery. The Yosemite Installer is also a bootable application.

I made the whole procedure , downloaded Yosemite apple store , I created a USB 2.0 boot disk , did the installation , did reset SMC , NVRAM , and after all procedures , sent to all updates of Yosemite version , updated everything right . restarted ... I tried to do the bootcamp , it partitions , restart the machine and all black again. It's like he just caught and nothing happens! : /

I do not know what to do! I appreciate your help, most believe it has no solution! Should be some firmware update or something else that Apple should have done, and my machine just this unable to install windows .

PT_BR:

Fiz todo o procedimento, baixei o yosemite da apple store, criei um disco de boot USB 2.0, fiz a instalaçao, fiz o reset SMC, NVRAM, e apos todos os procedimentos, mandei fazer todas as atualizações da versao yosemite, atualizou tudo certinho. reiniciei... Tentei fazer o bootcamp, ele particiona, reinicia a maquina e tudo preto novamente. É como se ele travasse e simplesmente mais nada acontece! :/

Não sei mais o que fazer! Agradeço muito a sua ajuda, mais acredito que nao tem solução! Deve ser alguma atualização de firmware ou alguma outra coisa que a Apple deve ter feito, e a minha maquina simplesmente esta impossibilitada de instalar o windows.

Do you have access to a W7 DVD? It would be a good test to see if W7 has the correct drivers for the Intel HD3K GPU on your Mac. W8 should also have them. I have installed W8 on a 2012 13 in model using non-EFI boot which has an Intel HD4K GPU without any issues.

Can you tell what it is the driver exactly my MBP and I can put the driver in the windows installation?

I tried with Windows 8 and 8.1 and all versions is black screen !

Only I managed to install the W8 and W8.1 using EFI mode. however, the audio does not work!

I thought to do this, add the DVD W7 , W8 or W8.1 video drivers necessary for it to work , but I'm hopeless that works.

PT_BR:

Você sabe dizer, qual que é o driver exatamente do meu MBP e se eu posso inserir o driver na instalação do windows?

Tentei com o windows 8 e o 8.1 e em todas as versões fica tela preta!

Só consegui instalar o W8 e o W8.1 usando o modo EFI. porem, o áudio não funciona!

Pensei em fazer isso, adicionar ao DVD W7, W8 ou W8.1 os Drivers de vídeo necessário para que ele funcionasse, mas estou sem esperanças que funcione.

Loner T! You may be able to help, after hours of research and reading a lot of your replies to many of the people on here, I am also having issues with getting my audio to work in bootcamp.

My setup:

I have a MBP Early 2011, I have removed he original hard drive and installed a SSD in its place, I also purchased a caddy and removed the optical cd drive and installed the original hard drive in its place.

Now I have installed windows 8.1 pro and it's up and running ( this took hours and hours for me to do, due to from what I can tell what you mentioned around the issues you describe with EFI boot on preUEFI Macs ( which is how I was able to install my windows copy).

The only way I could get it to work was by using Bootcamp assistant, I did have to remove the "pre" in the info.plst file to allow BCA I guess to let me create a USB from a ISO.

Now I am in windows and have tried again hours and hours (realistically in the past 3 days ive probally spent close to 16-20 hours trying to fix this with reinstalls and drivers and updates... Just cannot get the sound to work! All other functions seem to be in tact (brightness buttons, webcam, trackpad)

Please help

On the 2011 Macs, EFI layer does not expose the embedded Audio devices properly. Do you still have the original Optical drive that you took out from the Mac?

Yes, I purchased a superslim optical enclosure to put the optical drive in.

Is it possible to

1. Move the designated Windows drive to the main bay of the Mac, and,

2. Re-install the Optical drive to get Windows installed.

Once Windows is installed, replace the optical bay/drive with your non-Windows drive.

Is this the only solution?

If done this way, could I re-install the SSD into the main had drive bay, and then removing the optical drive again and replacing it with the original HDD that would now have windows install on it?

You can move the Windows disk to the Optibay, but it may cause issues with Windows booting.

But why? That is the question that never gets answered --- The response 'just re-install using BOOTCAMP' is a solution but doesn't answer/explore the issue at all. I really want Apple to chirp up about it- I send them an email a week essentially asking the same question over and over again to no avail (I will keep trying though).

The reason why I reject the 'EFI Boot' issue is because I, like many others, run various linux distributions in pure EFI mode and all devices work, are seen etc.... This is even true with FreeBSD 10. So if the open source community, with far less resources mind you, can figure it out ; why let Apple and Microsoft off the hook.

I just want an explanation why. Yes, it is clear that EFI boot without the CSM layer of bios emulation is part of the issue ---but why? Why does linux do fine, why does FreeBSD do fine --- Those OS's see the Intel PCI audio bridge (device 27 on PCI 0) and the cirrus codecs and the various inputs and outputs out of the box!

So why ? Not an answer saying we should of used BOOTCAMP

The primary issue is related to device probes to query the EFI layer. OSes that support EFI do not rely on CSM-BIOS at all. FreeBSD or Linux distributions are primary examples of such. For Windows, installed in EFI Mode, the device probes do not collect embedded device information, and rely on CSM-BIOS.

On Macs from 2013 onwards, EFI and CSM-BIOS behave the same, so an OS can be installed using either. Legacy BIOS is still tied to an MBR from a partitioning perspective and has other limitations. 2012 Macs are an interesting implementation of preUEFI model, because they can install W10 in UEFI.

Try running MSinfo32 on a 2010 Mac with an EFI Windows and you will see a significant set of devices missing. Despite all this, Macs with EFI 1.1 on the OSX side work perfectly as do many Open source OS variants. Does that help?

Ok, I understand I may be a bit late to the party, but I had just solved the audio problem with Windows 10.

I copy my answer here from another similar thread.

I have a MacBook Pro 13" (mid-2012), 500 GB SSD and 16 GB RAM.

This issue boils down to a poor EFI support on older MacBooks. Boot Camp assumes it can do just fine with this, when creating a USB installer and partitioning the hard drive. However, EFI boot mode exposes devices in a different way, which effectively leads to audio not working.

Basically, the solution is to use a legacy MBR boot mode, when installing Windows. However, due to Boot Camp's tricky partitioning of a hard drive, legacy mode will not allow Windows installation to that partition (the infamous message "Windows cannot be installed. The selected disk is of GPT partition style" etc.).

To install Windows 10 without any of these problems, I did the following:

0. Saved the latest Windows drivers to a USB stick via Boot Camp.

1. Burned a Win10 ISO image to a DVD.

2. Merged a Boot Camp-created partition back to a single MacOS partition (did that via Boot Camp).

3. Created a new partition for Windows 10 in a Disk Utility (I assigned 100 GB, formatted to FAT).

4. Re-formatted this new partition to NTFS, using a third-party software. I used Tuxera NTFS for Mac (http://www.tuxera.com/products/tuxera-ntfs-for-mac/). It has a 15-day free trial.

5. Put my fresh Win10 DVD to an optical drive and rebooted, while holding Option key (alt).

6. In a boot options screen, I selected DVD "Windows" (Do not choose EFI boot.). Windows installation started.

7. In a Windows Installer Disk selector screen, I chose to install Windows to that NTFS partition created earlier.

It all went smoothly afterwards. Windows reboots a few times during installation process, as usual. In these cases please hold Option key during reboot, and then select to boot from hard drive "Windows".

After Windows is installed, do not forget to install latest Windows drivers from your USB stick.

NB: Before all that, I also played a bit with marking my MBR partition from hybrid to protected (see here: http://fgimian.github.io/blog/2016/03/12/installing-windows-10-on-a-mac-without- bootcamp/). However, I am not sure this actually was important in my case.
