No sound in my Hackintosh build (Yosemite)

I've been "hackintoshing" for a few years now and I had no problems until I upgraded to Yosemite. My integrated sound card is not recognized anymore.

First my build:

• i7-3770K


• 16Gb RAM


• AMD Radeon 6870HD 1GB


• Gigabyte Z77-DS3H

I always installed the Multibeast driver in order to get sound out of my mainboard (I don't use the HDMI sound from my videocard). But it doesn't work anymore, with any driver.

Luckily I have a 5.1 headset that connects via USB. It works great because it has its own driver. But when it comes to use the desktop speakers, it doesn't work at all.

Any help will be much appreciated. Thanks in advance.

EDIT: Formatting.
