Motherboard Sound Issue

Not sure if this is the right forum to be posting this issue in, but I recently built a new computer, and everything is working as is should except one thing. The sound. I have installed the drivers from the Mobo disc, and it didn't work. I installed the factory drivers from Realtek and it still does not work, and I am currently contacting Gigabyte.com for some help as well. They told me to install a certain driver to which is still hasn't worked. USB Headsets work, just not the jacks on the back of the motherboard or the front of the case.

Specs:
Motherboard: Gigabyte GA-Z87X-UD3H
Processor: i5-4670
GPU: MSI 770

Any ideas or need more information let me know.
Thanks so much for the help in advance.
