HDMI not recognized

[TheFugas]

Hello to all the people who is part of this great forum, I come today to bother you guys with one very annoying problem and its this one:

I just bought my motherboard MAXIMUS EXTREME VI and i have it connected by HMDI to my monitor but it only reproduces the VIDEO but not the sound it is not even recognized by my pc as you can see in this pic.

I'm not using a Graphic Card, but the integrated with the CPU.


I have already comproved the cable, connecting it from my Laptop to the same monitor and works perfectly (video and sound) so I was wondering if the problem comes from my motherboard.

I thank any help you guys can bring me since now and from your time!
