Audio Output doesn't work

[TR537]

Hi Guys
I've just built my first Hackintosh. It runs just fine but I have a problem with the audio. I used a 3.5mm audio output cable to connect it to my speaker but there is no sound. I cannot run with the HDMI because I'm using two monitors and I only have one HDMI output on my graphics card. Also I can only choose my AirPort Express for audio output.
I'm using a GA-Z87X-UD5H Motherboard and my graphics card is a gigabyte windforce gtx 770, if anyone would have a solution I'd be very happy.
If you need any other tech specifications let me know.

No OS X audio on non native hardware. What have you done to enable audio?

Just to test the hardware part, I installed Windows 8.
Using a DVI -> HDMI cable I managed to have sound through the GTX 770 DVI connection and HDMI on the monitor side.
So from a hardware perspective, this setup works fine.

Now I want to replicate this setting on the Mavericks side.
Unfortunately, I do not see the option which would allow me to select the audio output.
This is what I can select from:


Is there a chance, that I can route audio through the GTX770 DVI connector, like in Windows?

Thanks.

PS: The audio on the motherboard is working fine, but I'd like to have it through the graphics card.

OS X HDMI audio is native only on native hardware, see Mavericks: HDMI Audio - AppleHDA
