I like to macro stuff together when one ability is NOT on the GCD… yeah, increasingly difficult these days. What made this really work was being able to NOT have to deal with error messages (need every help I can get to play with my guildies!). This code has worked just fine until recently:
#showtooltip Frostbolt
/console Sound_EnableErrorSpeech 0
/use Aquipotent Nautilus
/cast Frostbolt
/run UIErrorsFrame:Clear()
/console Sound_EnableErrorSpeech 1
I AM getting the audio warning, so I suspect what I have in there is wrong… can anyone help me out?
Have you figured it out yet? I’m still working on it… 
Nobody was responding here, so I posted a different thread. Tried some other ways (different commands). Nothing worked as it used to… leading me to conclude the most likely thing is they changed the way they parsed macros. Like if there is an off then on, it keeps it “on” no matter the “off.”
I really did not want to turn off ALL error audio warnings, just those I found in combat. THEN I got a new trinket that made me re-do my rotation where I no longer had the need to suppress.
It seems like someone would know… it is very frustrating…
Silentium Addon fixes this issue as of 9.0.2 you can get it on Curse
