No Audio Boot Camp Windows 8

I should have been more clear.

I am talking about a Windows 7 installation, not Windows 8. I have installed Windows 7 through bootcamp. I did this with a Windows 7 DVD.

I have tried this already but with no succes.

Found one solution that works after working through a bunch that didn't.

The audio drivers that come with the latest boot camp don't work to produce sound even though Windows is reporting that the device High Definition Audio is working.

The task is to update the device driver using the driver from Cirrus Logic which can be found at

http://www.stuffedcow.net/macbook_audio. Select "WinVista" version on this page or use this link to download the zip that contains the drivers at http://www.stuffedcow.net/files/CS4207_WinVista_Win7_32-64-bit_6-6001-1-30.zip.

First unzip the drivers to a file folder of your choice that you will need to remember as you will need to point to it later, e.g. c:\users\yourname\Cirrus_Logic

Next find the audio device in device manager. Can use Search Settings "device", select "update device drivers" or "device manager" and find "Sound, Video, and Game Controllers". Under this item, you should see a High Definition Audio device that is working properly., Right Click on it and select "Update Driver Software", then "Browse My Computer for driver software", then navigate to or paste the folder path into the location window. Click Next, and it will start looking for drivers in that folder/path.

It should find the drivers and complete the installation and when it is done your sound device should now be named "Cirrus Logic". Be patient at this step, it can take a few minutes.

Must reboot computer at this point and then sound through speakers or audio jack should be working!

Good Luck,

Although some 2006 machines have a 64 bit processor (C2D) there are limitations that make it essentially 32 bit machines. Their EFI is 32 bit for example and I know there are problems with some of the video hardware.

Let us know if W7 32 worked for you, my guess: it does. And possibly W10 too.

Good luck.

Already tried that. It is able to install bootcamp with the drivers but the sound doesn't work.

I will install the 32 bit version of W7 pro and get back to you with the results. Thanks for the advice!

I installed windows 8 through a USB in EFI mode, as a result I do not have any audio. ADB1973 wrote, "The problem is in EFI mode Windows 8 and 10 do not see the audio hardware from certain machines. My MacBook 8,1 (Early 2011) was one of them". I have a macbook pro early 2011 with a samsung pro 850 ssd. Is there a solution to this problem? Windows is not recognizing an audio device. Whats funny is I can connect to a Bluetooth device and sound plays out of it.

If you use the normal BC Assistant method, for a 2011 Mac, it creates a Hybrid MBR. If you used a USB to work around a dysfunctional Optical drive, the problem's root lies there. Macs prior to Late 2013 models are preUEFI and require a legacy BIOS/MBR based installation to work properly.

Only CSM-BIOS exposes the audio devices correctly.

I got mine working and I was going to post how I did and found my method very similar to the one suggested by Vo0d0o (pasted below). I went straight to the first Cirrus Logic exe file (CirrusAudioCS4206x64) and ran it worked. I've tried dozens of other things before, so maybe one of the things I previously tried took care of the second exe file...

From Vo0d0o:

This is a reall simple fix so if anyone sees this i literally did this about a minute before typing this post because everyone should feel stupid to how easy this fix is....

Navigate on you >MAC< to the Bootcamp application. Before this make sure you have a 8gb USB flashdrive formatted to Fat 32...windows default. Open Bootcamp app, and install the latest Bootcamp drivers onto the USB... I suggest naming the USB to SUPPORT all caps after doing this...

Navigate to Windows Partition... on boot menu....

Open up file explorer, click on you new SUPPORT drive, open up Bootcamp folder, then drivers, click on Realtek driver set up .exe, and install that (depending on your computer it will prompt you to restart it or not after installing). Next after rebooting or re-installing the Realtek driver.... head into the Cirrus folder...

>THIS IS THE MOST IMPORTANT PART ABOUT GETTING THE SOUND TO WORK!!!!!<

CLick on the second .exe driver manual download, and run it. IF YOU DON'T DO THE SECOND ONE FIRST IT WONT WORK. After the download is complete, click on the first Cirrussetup.exe and install that. After that is complete... when you go to test your Mac's sound... there will be a slight delay... followed by the nice obnoxious chirp on Microsoft's sound test.

Hello everyone.

I am so frustrated at this process of getting these audio drivers installed on my late 2011 MBP. I have tried every single thing; from updating bootcamp drivers, to installing .exe in certain orders, reinstalls, downloading the stuffedcow link and mapping the update to that folder with no success.

I have yes, booted it partitioned with an EFI boot, due to the fact I do not have a optical drive in this macbook any longer. I also used GTPDISK to get it to format on windows installation.

There has to be a way to do this, I hope someone can help me. I really need this to work for professional applications and its nothing but a disappointment 😟. Please help!!

You will not get Audio unless you use a BIOS/MBR installation on 2011 models. The devices are only exposed via CSM-BIOS.

An external Optical drive will not work. You need to disconnect the disk in Optibay by disconnecting the SATA cable till Windows is installed on the main bay disk. Use a VMware/Winclone method documented on MacRumours to install MBR/BIOS and test. Once tested, then connect the Optibay disk.

You will not be able to repair Windows in the future due to the lack of Optical drive.

I figured I needed to reinstall my optical drive back into the computer, just really didnt want to do this!! But thanks for the heads up, and i will give it a try.

Quick question, isnt VM ware/WInclone the virtual way of doing so? I want a full seperate partition on the main SSD drive.

Good that you have kept the Optical drive. 😉

Yes, it is. You will get a separate partition, unless you want to dedicate the full SSD to Windows only.

Looks perfect! Last thing though, as long as I made the install disk, and it is inserted, when the computer restarts after bootcamp, it will boot into the disk? And it should format correctly without using gpt disk to change the settings in terminal? Just making sure...

Remove the current EFI Windows installation so your disk can go back to a single partition and run BC Assistant, and look at the last option. It will be enabled once the installation DVD is recognized. Follow the prompts. This will also let you change the BC partition's size.

If you need to re-use the current partition, then you will need to use GPT Fdisk to create a Hybrid MBR so the Installer can see it and let you erase/re-format the partition. In this case, after the MBR is created, shutdown your Mac, Insert the DVD, boot and hold Alt/Option and choose the Windows icon (not EFI) and continue. This method does not allow partition size changes.

When you say "right click sound" do you mean right click the not working Realtek high definition audio? because when i select the folder with the cirrus it says i so not need to upgrade the realtek audio. Thank you in advance!

Hello Everyone ! I had the same problem with my mac but figured out the resolution ! You will need to boot up your computer to windows login and then if you have a mac osx installation disk you want to insert that in then double click the disk in my computer then choose the third option which should say bootcamp or something along those lines Then it will install all bootcamp drivers neccesary for your mac For EX isight camera audio driver things along those lines

Now just let the installer do its job it will say removing old realtek driver but dont worry thats ok its installing the new compatible one Then thats it all you have to do is restart and all of your drivers should be working properly 🙂
