trinket casting

[Catamer]

i used to have my trinkets on a seperate macro but I have just started using the trinket casting like this


/cast trinket1
/cast trinket2
/cast lightning bolt


this casts a trinket whenever they are ready however it makes a huge amount of noise about the trinkets not being ready to fire. I disabled the speech part of the error but it still makes a whining noise that is similar to not having a target or line of sight issue.
Is there anyway I can disable this noise on the trinkets only like /cast [no-noise-please] trinket

I get the same thing for my rogue with energy. I spam my attack button to use her attacks, but when i have no energy (like 80% of the fight) i have "not enough energy" all the time. Thank god i am the only one hearing it. I can hear a raid good yelling at me, wait till you get f*&%ing energy. It gets really old fast.
