Help with a macro

[memetootoo]

Hi, I'm using the following macro:

#showtooltip Lifebloom
/use 14
/cast [target=mouseover,exists,help,nodead] Lifebloom; Lifebloom
/run UIErrorsFrame:Clear()

But, whenever the trinket is on cooldown and if I use lifebloom it makes the really annoying whooshing you hear when items cannot be used. Is there anyway to get rid of that sound since I need to spam Lifebloom a lot?

Suprrsinly, I have the same marcro for regrowth but it does not make the same whooshing sound when the trinket is on CD:

#showtooltip Regrowth
/use 13
/cast [target=mouseover,exists,help,nodead] Regrowth; Regrowth
/run UIErrorsFrame:Clear()

Help would be appreciated.

wooshing sound? you should "i cant use that yet" or something along those lines.
