No Audio Boot Camp Windows 8

You have tried what Tsjuni? There's not much info in your posts. And what kind of machine do you use?

Did you try to install W8 through Boot Camp or did you try to install W8 using gptsync and/or did you make sure somehow you used the MBR/legacy (not the EFI) mode.

I can guarantee you if your not in MBR mode (see my earlier post) even trying to install the right driver does not work. 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.

AFAIK there are no people that got this fixed by just installing the right driver.

Since your iMac has a DVD drive did you burn W8 to a DVD and then install it?

Your Mac only support W7 32-bit or earlier. What is the version of Windows you are trying to install?

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,

I only tried it with a 64-bit installation of W7 pro. I can try a 32-bit installation as a last resort.

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.

how to install bootcamp on windows 7 64 bit on late 2006 imac

and, following from the last post there...

http://michael.anastasiou.me/boot-camp-x64-is-unsupported-on-this-computer-model /

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 have experience about this and success to fix this problem, visit the following link for all steps, step by step until finished.

I promised to report back. Installing the 32 bit version of Windows 7 was a success. I now have sound. Thank you all who helped.

Excellent. Please ensure you have OS X and Windows backups.

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.

As stated in earlier posts force install W8 in (hybrid) MBR mode, I think I wrote a how to here too.

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.

If I burn the iso to a dvd, is there a specific DVD I have to use?
