I wanted to add ambient sound effects in my map, like for example, let's say you go outside a building, I would want the sound effect of wind blowing to be playing in a loop. But I would want it to so you can't hear it anymore when you go back inside a building. I've looked at tutorials on how to do this, but it hasn't been working for me... not sure what I'm doing wrong. Any help would be appreciated.

You can use: http://wiki.modsrepository.com/index.php?title=Call_of_Duty_5:_Sounds_with_Line_Emitter
or you can use: http://wiki.modsrepository.com/index.php?title=Call_of_Duty_5:_SP_-_Enviromental_Audio_System
or you can modify your existing soundalias using dist_min and dist_max.

Yea I tried that 2nd tutorial and it didn't work, idk what I did wrong. But ill try the first link
