Q: Mac mini Late 2014 Boot Camp Windows 7 sound issue

Hi,

 

I'm wondering if anyone can help me with my Mac mini (Late 2014) and Boot Camp (Windows 7). The problem I'm having is that there's no audio when I boot into Windows 7, though everything works fine under OS X. After installing Boot Camp and Windows, the audio worked perfectly up until yesterday, and now there's nothing. I've tried updating as well as uninstalling and reinstalling drivers, but this hasn't helped at all.

 

When I open Volume Mixer and Playback Devices, the sliders show that audio is playing, but I hear nothing - either from the built-in speaker or when I headphones.

 

The Device Status indicates that "This device is working properly" and that the drivers are up to date. Tthe following drivers are installed:

 

dmk.sys

HdAudio.sys

ksthunk.sys

portcls.sys

SysFxUI.dll

WMALFXGFXDSP.dll

 

Has anyone else encountered this issue, or does anyone have any tips on how I might fix this?

Mac mini, OS X Yosemite (10.10.2), Mac mini Late 2014
