Audio drivers not working? -Bootcamp

I recently installed Bootcamp using the USB windows provides when buying windows 10, but when I tried to install windows some, Mac functions didn't work. For example my WI-FI and my keyboard functions. So I had to get the boot camp support software for my MacBook Pro. So I go back to Mac OS X and install the support software using Bootcamp. After installing the Setup.exe on my USB I go back to windows and use it. after its done everything works perfectly except for my sound. I hover my mouse on top of the sound icon it says no audio output device is installed.

So I go check the drivers and I found an audio driver called cirrus logic. So the sound drivers are installed But they don't work? I own MacBook Pro (13-inch, Mid 2012)
