No Audio Boot Camp Windows 8

exact same thing happening with me. I called apple and they told me to call microsoft which told me to trade it for another version of windows 8 that ended up not being here T_T

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

I found that if you get a new windows ISO and new bootcamp support files it is fixed now

Hi!

First, excuse my poor way to explain because Im from Costa Rica in Central America and my native language is Spanish. I have a Macbook Air with maverick 10.9 and windows 8 installed, everything is fine except the sound, there is no sound at all. Lucky to get to this post, download the Cirrus Logic file that you recommend

http://www.stuffedcow.net/files/CS4207_WinVista_Win7_32-64-bit_6-6001-1-30.zip.

and follow the installation procedure, but I have one question: Which one of the long list of models I have to choose? Any help or suggestion to get the sound finally in my laptop will be appreciated!

I have to mention that I download to a USB drive the latest version of bootcamp directly from my other OS in the same laptop and when I try to run the bootcamp.exe the system says isn´t compatible with my version of 64bits. Apparently this is the only real solution but Im stuck in the final step to close this painful chapter in my life, hahaha.

i'm having same problem too,

Macbook pro 13 inch boot camp windows 8.1 pro, early 2011

Installed windows 8.1 pro using usb EFI Boot / EFI Mode,

use the GPT to change the BOOTCAMP disk permission

download and installed the newest bootcamp driver for windows

5.0.5033

everything works except audio.

2. Go to device manager.

• Right click on sound and select " update driver software"

  select " Browse my computer for driver software"

  • select " Let me pick from a list of device drivers on my computer"
    • select " Have Disk"
      • map to the driver location and select the .ini extension file.
• wollaaaaz..... you should be all set.
• enjoy the sound of Apple .... 🙂

😟

after i map to the driver location and select the .inf extension file, still not effect..

Issue might be due to HDMI Output.

ISSUE:

I had a secondary monitor connected to my MAC PRO over HDMI and this was causing the issue.

My MAC was sending the audio over HDMI instead to the speaker.

CHECK:

If there is sound coming from your audio jack, this is the problem.

FIX:

Change Default Audio Output.

STEPS:

Open Control Panel

View by: Small Icons

Double Click Sound

Under Playback Tab.

Highlight Speaker

Set Default.

Thanks Folbaj. Totally worked! I've been living w/o audio on my Bootcamp windows for a couple years now. Ran into a little hurdle when trying to update my Driver. When navigating to the Cirrus Driver make sure to hit "next", not "Let me pick..."

I did what you said but I get "The folder you specified doesn't contain a compatible software driver for your device. If the folder contains a driver, make sure it is designed to work with Windows for x64-based systems."

I'm on win8 x64 EFI boot.

it worked for me like a charm.

many thanks!!!!

"high definition audio device" relates to the audio link via the display port (which can support video and audio via thunderbolt, hdmi...). it's the graphic card driver which has to be updated, not the audio card driver

What worked for me on a MBP 2012 (Intel HD Graphics 4000, windows 7 64b) was to download and install the latest version of the Intel graphic card driver directly form Intel website. Unfortunately, this driver is not included in bootcamp nor proposed in windows update and has to be installed manually.

Still no sound and "High Definition Audio Controller" still says

This device cannot start. (Code 10)

{Operation Failed}

The requested operation was unsuccessful.

Installed Windows 8.1 with the ISO and Drivers from Bootcamp

installed last HD4000 from Intel website,

Updated Diriver with Cirrus Logic CS4207_WinVista_Win7_32-64-bit_6-6001-1-30.zip

"The folder you specified doesn't contain a compatible software driver for your device. If the folder contains a driver, make sure it is designed to work with Windows for x64-based systems."

MBP Win 8.1 x64 EFI Boot

Thank you folbaj, it works now.

Hi everyone,

I have the exact same issue as colibry here and tried everything out found here and elsewhere. Except:

Manual install wouldn't work because of that error message. I remember to have had the same issue last year installing Windows 7 where downloading and manually installing the drivers would totally fix the problem.

Does anyone have a clue?
