The Play/Pause, Stop, SkipForward and SkipBackward keys on my CM Quickfire TK keyboard have suddenly stopped working. These keys were working before, I don't know what has changed to make them not work.
All other special function keys such as mute and volume control still work correctly. I believe these other keys work because they control the OS volume, and do not send commands to applications.
These media keys do not work in any media player I have tried (FB2K, VLC, MPC).
I have already tried using the method described here, to no result.
