No Sound with Gigabyte G1.Sniper Z97 Mainboard

I'm a Linux beginner and installed Ubuntu 14.04 but I have sound issues. I've got onboard sound and my motherboard is called Gigabyte G1.Sniper Z97. I already tried to fix the Problem with google but as a Linux beginner i've got to my limits. Here is the output of some things you might need: cat /proc/asound/cards

I also tried to reload alsa and to reinstall it but i still got no sound. I even reinstalled ubuntu but i didnt get any progress with my problem. I hope you guys have an idea.

I had this same issue when trying to use this board with Manjaro. When I installed Windows to see if it would work there, it didn't until I installed the audio drivers that came with the board. I think we have to find linux versions of the audio drivers for the board. I believe they were Realtek drivers.

Sorry for the newbie answer. But I'm trying to switch to linux too.
