WotLK Make Spell Fizzle Less Spammy?

[fidelitousone]

I noticed that when you fail to cast a spell, it makes a certain spell fail sound. However, whenever I try to repeatedly cast a spell and it fails to cast the sound plays literally for each time I press the button and it's quite annoying. For example, when I'm in a stun and I keep spamming an ability to cast so I can get that ability off right after the stun.

Is there anyway to disable this sound specifically or make it less annoying? There's no option in settings for it.

I found out how to do it!

Here's a Wowhead link that works with this client.
