I've been using a Logitech Clearchat Comfort headset for a couple months now, and never had any issues with it until the volume adjustment buttons, that's the thing in the middle of the cord in the stock picture above, decided to quit on me. Sound and other forms of volume control work fine, but I use the headset for everything from gaming to youtube to plain old music playing, so being able to easily change the volume is nice.
The headset uses default windows drivers, so that isn't it, and it hasn't suffered and physical damage that I know of. The only explanation I can easily come up with is that I recently started using Litestep, a windows shell replacement, but I don't see how that would break it. Any ideas?
EDIT: I have confirmed that litestep is causing the problem, but that's all I know.
