Huntsman keyboard volume control not working right

My Huntsman keyboard is now just over a year old and the volume control knob is working poorly. If I turn it super slow, it will adjust the volume. Otherwise, it just goes up by one and then back down. I've googled this and it seems to be a hardware issue. Unfortunately, I am out of warranty. I have the most recent firmware and the keyboard is plugged directly into the computer. Am I out of luck? Thanks, Dan
