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.
