No audio : Windows 10 Bootcamp

Question

No audio : Windows 10 Bootcamp

Hi everybody. I begin to apologise because I'm french and my english is not perfect. 🙂

So, you are, the apple community, my last chance.

First of all : I give you my set up, that will be usefull.

Config : Macbook pro late 2011

Upgrade with SSD 850 evo

So I have 1 HD and 1 SSD.

I recently instaled Windows 10 with Bootcamp on the Hard Disk. Everything works well, but I don't have audio.

I had installed the latest Bootcamp (Drivers) on Windows 10. But at this point I had no audio.

I saw on "device manager" that the "Hight Definition audio codec" is installed, but badly. I can see a Yellow exclamation mark and an error in the property (Code 10).

Then, I tried to uninstall this Driver (directly in the device Manager), to install it better. But nothing looks work.

I had also tried to download directly the latest driver on the Realtek Website.

I have more information for you : If I plug a jack I have the same issue.

In the Mac partition : The latest OS Yosemite is installed

When I installed W10, it was on an empty partition, with a boutable USB drive.

I tried the latest Bootcamp and also 5.1.5626

I really hope that you'll can help me.

Thank You

MacBook Pro, Other OS, Windows 10

Please do not use drivers that are not valid for your specific Mac year/model. It can cause issues. Is your Windows installed using EFI Boot?

From System requirements to install Windows on your Mac using Boot Camp - Apple Support, please verify that you are using the appropriate drivers

W10 does not execute drivers using setup.exe from the Bootcamp Folder correctly. You will need to run the .exe file in the appropriate directory under Drivers with Administrative privileges and in W8+ compatibility mode. Please try and test.

This is already tested.

Yes it's an EFI boot.

I don't have any idea.

Actually, when you say " Is your Windows installed using EFI Boot?" I'm not sure.

The only thing that I know is : when I start my computer (with Alt Button), I need to click on UEFI boot to log in in Windows 10.

Can you check the installation information? This is from W7. You should see a similar screen for Windows 8 and Windows 10.

Mode Bios needs to be Legacy or BIOS. UEFI is not supported on your Mac. You will need to remove the current installation of Windows and re-install using Bootcamp Assistant only, and without interrupting the install. You should not use Alt/Option key till you see the screen which asks you to choose the Bootcamp partition of where to install Windows.

Hi,

Before I start, I Just read Loner T's reply, I thought Windows 10 (and 8) wouldn't let me just format the partition and force the EFI partition creation. If it's not the case and "It just works" sweet!

I have a Macbook Pro 13" (early 2011) and I had the same problem. After trying hard for a couple of evenings I was finally able to make the audio work.

The problem seems to be that the audio chip set (Cirrus Logic 4206B (AB28)) isn't detected by Windows 10 (even 8.1) when booted in EFI mode.

I tried many combinations, many different drivers and it didn't work until I did this:

Basic: Remove Bootcamp Partition, Recreate Bootcamp Partition + drivers(USB stick plugged and Windows 7 dvd inserted), Install Windows 7 + Bootcamp (should pop upon reboot after install), Upgrade to Windows 10, Repair BootCamp for windows.

1- Removed BootCamp partition:

Windows 10 created 1 EFI and 1 normal partitions and bootcamp wasn't able to delete 2 partitions, I had to use diskutil to remove the 2 partitions that appear as 1. I did domthing like this: sudo diskutil eraseVolume JHFS+ deleteMe /dev/disk01s4 (s4 being the bootcamp partition).

Then I went in Disk Utility in OS X and reformated the partiton as FAT, went in the Bootcamp Application and Removed Windows Partition option.

2 - Recreate Bootcamp Partition

To be able to do that you need a Windows install disk in. I Inserted a Windows 7 Pro x64 disk and plugged my usb key so Bootcamp installs drivers on it.

3 - Install Windows

when it reboots Windows 7 install starts,

Just click on format on the bootcamp partition and click next and it'll install Windows 7 without a new EFI partition.

It'll reboot and Bootcamp install will pop automatically at one point.

4 - Enjoy sound in windows 7, detected as Cirrus Logic 4206B (AB28)

5 - Upgrade to Windows 10 with the Media Creation Tool (http://www.microsoft.com/en-us/software-download/windows10) choose upgrade my PC now.

6 - Repair BootCamp

7 - Disk Cleanup Utility ( check old windows version, it'll free 10GB)

8 - Boot back in OS X and don't use OS X for months.

PS: You need a valid Windows 7 key and it must be activated for Windows 10 to accept to upgrade

Can you post a screen similar to the W8 I posted? Re-installation defaults to BIOS.

Ok. I'm gonna try it. But I remember that during the instalation, with this way, I cant install Windows. They ask me to formate in GPT or I cant really remember.

If BCA failed to create a proper MBR, it can be manually created if you see the GPT vs MBR error message.

I tried only with bootcamp. Without press ALT. After restart, I had this screen

Then I pressed Alt

I selected Bootcamp to format it

But After I had thoses messages

After, just to try it. I had press Shift + F10 to convert my partition in GPT. Everythings works well. But after the instalation of W10, I had the same issue : No sound and also UEFI (in Bios Mode)

Do you have an idea?

Boot back into OSX, and post the output of

diskutil list

diskutil cs list

sudo gpt -vv -r show /dev/disk1

sudo fdisk /dev/disk1

This error can be corrected easily.

I assume from your earlier screen shot that you are trying to install Windows on disk1 (750GB) disk.

If you plan to use the entire disk for Windows, my suggestion is to format the disk as FAT32 and MBR only. This does not require a Hybrid MBR at all.

If you plan to use multiple partitions on disk1, then you need to create a FAT32 partition on this disk of the size you need Windows to be. This partition would then be added to the MBR using a utility called GPT Fdisk available at http://sourceforge.net/projects/gptfdisk/ .
