Any way to remove the "click click click" sound when activating ability?

[xat1114]

Does anyone know a way to remove or stop the "click" sound from activating an ability? Whether you use a hotkey or left mouse button on the ability, it makes a short click sound, and it drives me crazy as I spam my hotkeys.

For what it's worth, the sound file is in Audio.myp, and I think its called "int_button_click.wav"

In WoW, there was a way to stop that games click sound by making a blank zero byte file with the same name and putting it in the data directory.

Does anyone know of a solution?
