Question: Windows 8.1 Pro No Audio Output Device

Hi, I recently installed Windows 8.1 Pro on my laptop using Boot Camp. Everything works perfectly, except for the audio. It says there is no audio output device installed. Can someone give me the proper link to fix this? Also, clear instructions would be great because I am not very experienced with this.

BC 5.1.5621 is a collection of drivers not a single unified driver. You can see it on the USB drive on which they get downloaded and written to. The collection in the zip file is what Rudegar is referring to. There is a Realtek, Intel HDA, and many other individual drivers in the zip file.


If you cannot see the devices in Device Manager in Windows, then it may be an issue. Did you install W8.1 via EFI Boot on an older than 2013 Mac?
