Boot camp sound drivers for 2014 27" Retina 5K iMac?

Where can I download sound card drivers for Windows 8.1 64-bit for use on my 27" Retina 5K iMac?

The device manager shows 2 "High Definition Audio Device" devices under "Sound, video, and game controllers", but no sound comes out of the speakers. I am able to adjust the volume, but I can't hear anything under Windows.

I've tried manually installing Cirrus Logic CDB4206 drivers, but they also didn't work.

Also, where can I get proper Boot Camp Support Software? The versions I tried all say "This version of Boot Camp is not intended for this computer model."

Where can I download drivers so that I can get sound to work under Windows?

The only way to get BC drivers for a 5K is via the BCA. Boot Camp: System requirements for Microsoft Windows operating systems - Apple Support shows BCA as the source.

Find a USB2 flash drive, run BCA, and just click on Download drivers. You can then use setup.exe in Bootcamp folder to install/repair drivers.

Can you post a screen shot of Device Manager with all your devices?

Thank you, Loner T! You solved my problem!

I used an empty WD My Passport 2TB drive to run boot camp and install Windows 8.1. I should have checked that drive for the boot camp software first.

As long as you have no devices in Device Manager with a yellow triangle and an exclamation mark, you should not have any more issues.
