@Zethex - If its an external mic then unplug it from the computer and see if the error is still happening.
Also make sure that you have the correct drivers which is found here:
ASUSTeK Computer Inc. - Motherboards- ASUS P5K SE
Click the Download Tap > Select OS > then Choose Audio.
@CaponeLockdown - Next time its best if you make your own post so we can get the right answers for both of you. Chances are you don't have the same computer or the exact problem as him.
I recommend these:
Windows 7 & 8, Office 2013, Photoshop CS6, IE11
Security Essentials, Asus, Dell, Samsung,
Intel, NVidia, Xbox One, Android, Gigabyte
