No Audio Boot Camp Windows 8

Hi,

The best thing to do is:

Install Windows 7

Install the boot camp drivers appropriate for your iMac

Upgrade to windows 8 / 8.1

Re-install boot camp drivers (as windows 8 may return to default drivers.

The above is what worked for me and should work for others also.

If you wish upgrade to Windows 10
Re-install Boot camp drivers if needed.

The above is what worked for me and should work for others also.

I don't know if this will help, but it helped me and it solved my problem.

1. Hold "COMMAND & W" to open Search

2. Type in "Troubleshooting" and press "Enter"

3. Select "Troubleshoot Audio Playback" under "Hardware and Sound"

4. Follow the instructions

Good luck!

After a huge degree of troubleshooting i realize what you say about installing windows 7 then upgrading will probably work on a newer model machine with EFI 2.0 i believe, but on an older model using EFI 1.1 freezes when forcing an EFI boot with windows 7 and in most cases just by selecting EFI boot it actually defaults to BIOS emulation.

Im using this on an iMac 12,1 (Mid 2011)

What I've tried so far with Windows 8.1 and have had no success is installed:

Boot camp - Various versions.

Cirrus drivers - Error "not compatible, or 32-bit driver" - I believe the error when using "Have disk" has to do with the fact that the device is detected as a system device and not an audio controller. You'll notice the auto populated devices is different from a normal audio controller.

Realtek Drivers - Same as Boot Camp.

Intel HD grafx/audio - Same as Boot Camp

If anyone knows of a way to trick windows into thinking this is not a system device and something else i think the cirrus drivers will work, or maybe even remove the HW check prior to install. Its just a theory, but I've tried every trick under the sun.

The ORDER you uninstall and re-install drivers is important. Assuming you are using the correct Bootcamp* (as it has the windows drivers to fix this problem) for your version of Windows, then the sound problem is usually a mix up in audio drivers installed.

I've put a detailed explanation and solution here ( No Audio ( Bootcamp ) ) - see my reply part way down - that should get around most peoples problem when the 'high definition audio' drivers have installed with windows and they are simply the wrong ones.

*The solution has links to let you know, but basically the latest Bootcamp 5.1.xxxx (comes as part of latest Yosemite or can be found on apple support) is fine for Windows 7 to 8.1 and most modern hardware since about 2009. But there are a couple of exceptions so just make sure you have the version for your hardware (also a link in the post after my solution - thanks to Loner T for linking to the official Apple list of Bootcamp versions to compatible Hardware)

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,

Darryl

This worked for me. I have an early 2010 MacBook pro 17". I had just formatted my OS X (re-installed Yosemite) and deleted/recreated a bootcamp partition running Windows 7. After these operations I had no sound on the Windows side. After trying several common solutions, including the RealTek drivers, I found that Darryl's answer finally fixed the issue.

Thanks Darryl and thanks for posting.

I just got it all working today. For those that couldn't detect any audio device, the main problem is you installed your window 8 in EFI boot mode or what ever it's called and this is wrong. I installed my window 8.1 pro on my MacBook Pro mid 2012 via EFI mode and my sound didn't work. It couldn't detect any audio device and there was an exclamation mark with yellow background on "High definition audio controller" (sort of). So I reinstalled the window 8.1 pro and reinstall it but this time i did it properly. Instead of choosing to install in "EFI boot" i chose "window" and got it installed on my laptop and BOOM the sound is working.

Thanks me later 😀

i have real experience about this problem and the problem fixed but installing Windows 8 on Macbook Air,

Using Boot Camp Assistant you can download all drivers needed for Windows 8 that installed on Macbook. After finished installing Windows 8, login to Mac and open Boot Camp Assistant and download all drivers ( Windows support ), save on the flash disk and we can install this on Windows 8. the detail steps shared on driverchipsdotcom,

I have try and all drivers working well

+1 Minticon is right. After 3 days of research i'm absoluty sure it's an EFI problem.

So the solution for my 13 inch i7 early 2011 MacBook Pro 8,1 was:

1: Make a partition for Windows

2: download and install gptsync to check if your GPT and MBR are the same, in most cases they are not, resulting in an error message when you try to install Windows, i'll elaborate on that later* download gptsync from here: http://www.insanelymac.com/forum/topic/177505-enhanced-gptsync-tool/ use the 0.3 version

3: in terminal let gptsync check your GPT and MBR and let it sync them.

I couldn't do this under El Capitan had to use 10.9.5 to be able to do it. Maybe Yosemite works, Mavericks did

4: I had to install Windows from DVD on my MBP 8,1 in order to get the legacy MBR option holding down ALT on startup

you can choose between Windows and EFI-boot, Use Windows or you'r screwed like Minticon said.

5:* when you install Windows 10 (or 8.1) ... and you get the error message. Can't install on a GPT disk or something similar, your MBR and GPT are not synced. Only after syncing with gptsync I was able to use the legacy mode.

remark: I started using a tweaked bootcamp assistent to be able to boot from a USB stick, on my MBP 8,1 that was a dead end because using USB I was not able to boot into legacy mode that way USB only offered EFI-Boot

Somehow using (virtual/synced) MBR is the only way to prevent the notorious Code 10 Can't start audio device blablabla) from showing up.

Using MBR my HD audio installed correctly as: Cirrus Logic 4206B AB28 on teardown pictures from macfixit I saw my MBP had the 4206B CNZ chip, that was not enough info to help me out. Minticons info finally brought me on the right track.

hope this helps, w10 works perfect now.

I have tried this but with no succes.

After installing the driver it gives me error code 10. This device cannot be start.(code10)

Could anyone give me some advice on what to do?

Check Device Manager and look for any devices which have a yellow triangle with exclamation point. The driver may be installed with incorrect privileges. Re-install the driver using Administrative privileges and compatibility set to W7/W8+.

I have installed it with the correct privileges. I have re-installed them just to be sure but nothing changes. It keeps giving me error code 10.

What is your Mac year/model?

That would be a late 2006 17" iMac. The MA590LL to be precise.
