Problem with playing sounds

Why doesn't my sound-trigger work?

+Events
Unit - A Unit enters Endor <gen>
+Actions
Sound - Play Hey Hey Hey <gen>

Hey Hey Hey is the variable for a sound from the Pitlord.
I have tried alot of sounds but now one works. Only when i play music as a soundvariable it will work, but not sounds..

You should do this:
Go to the sound editor then doubleclick on the sound you have selected and there un-tick the 3D stuff and there you have it.

haha! It worked!
Thank you!
