Having a problem on a Z87 Extreme4 along with version of the Realtek drivers.

The issue is that the headphone output (Sony MDR-XD200 plugged into the front jack) is a lot louder than my speaker output (generic Creative Lab speakers plugged into the rear jack). Easily twice as loud.

I tried to figure out if there was a way to independently set volume levels for the front jack but couldn't find anything.

Has anyone run into this issue before and if so, is there a solution?
