Asrock motherboard audio issues

[Vengeance BM]

Hello everyone!

 

I've encountered a problem this morning when I turned my computer on and plugged my headphones in to the front panel audio jack. There was no sound coming out, only white noise. I've tried plugging headphones in the back too, but it still only made white noise. My motherboard is Asrock Z97 Professional and it has Sound Blaster audio chip. In the past everything worked flawlessly, even Sound Blaster drivers and software. I've checked all the connections and tried to re-install the drivers, but nothing helped. Could it be just a defect motherboard?
