sound and weather problem

ive got some problems that i need some help with to solve, it seem that either sound or music wont work in my cinematic i've tried these to triggers: play sound and play music but when i test the cinematic all it does is play the default tune, please help.

my other problem is weather, i want to make it snow and i use the trigger:
enviroment- create at region 2 the weather effect northren blizzard, but nothing happens.

I had that problem with weather too. All you have to do is make a second trigger for the weather. "Turn Last Created Weather Effect - On" or something to that effect.

Thanks, it worked, just need someone to help me with the sound problem now

This happened to me as well, one of the problems may be that your sound has a very low volume, to check this you can go to the sound editor and double click on your sound(when i want my music i import it as a sound) And set the
volume - from 0 - 127(how loud it is with the speakers turned up high)
effect - default
channel - general

in the triggers do

Sound - Play sound

then just pick your sound and it should work in game

try adding a blank mp3 file. right when the cinematic starts, game time = to .01 seconds, play that file. make sure you have a trigger turning off the default music with map initialzatioin as the event. Also make sure you arn't setting the map initialzation as the event for your music. If those dont work just tell me.
