Sound triggers help

Im having trouble getting sound triggers to work, i want the sound to play for my custom spell. I have added 'play sound' action, but it doesnt seem to be working. Any help?

What does your trigger look like?

Event
Unit - A unit begins channeling an ability

Condition
Ability Equal to ( my spell )

Actions
Wait 1.9 seconds
Unit Group - Pick every unit in ( my unit group ) and do ( animation attack - 1)
Sound - Play DivineShield<Gen>

questions should be posted in the Map Development Forum.
