Nov 10, 2015 12:16 PM in response to AdB1973by skelly057,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.

Nov 10, 2015 4:43 PM in response to skelly057by Loner T,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.

Jan 18, 2016 9:06 AM in response to Vo0d0oby emetiha,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...
5k imac, windows 10.
**************
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.

- create a folder and extract the files on your desktop or any location where you can find map it while installing the driver manually.
- Folder created will be: CS4207_WinVista_Win7_32-64-bit_6-6001-1-30
2. Go to device manager.

Sep 22, 2016 5:46 PM in response to easiest_dinnerby jswarb,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.

Sep 22, 2016 6:04 PM in response to Loner Tby jswarb,I have since used the MS Tool to burn a bootable dvd disk. I currently have a portable/external optical drive. How do I install via BIOS/MBR with this setup?
Thanks for the quick response !

Sep 22, 2016 6:29 PM in response to jswarbby Loner T,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.

Sep 22, 2016 6:32 PM in response to Loner Tby jswarb,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.
