Mute anoying sound

[MuteMuteweferf]

Hi,
can anyone help me out please? I need to use one button macros (one arm lost) and no mater which class i play, if the macro try to fire off a Spell that is at CD, it makes a "whooosch" sound - every 2-3 Secound. I dont want mute the whole game.
For example : Marksman Hunter - Spell : "Sidewinders" - if they are at CD and the macro tries to use it - i get "wooosh".



I would be realy happy if someone could help me.
Max
