Teleport won't play sound

[<LT>YosemiteSam[NL]]

I made a teleport with sound and it worked fine but all of a sudden the sound stopped working.
When I replace the sound with another different sound with exactly the same soundalias settings but another name (changed the script and stuff to the new name)...it works.
I also changed the name of the sound i want to play but that strangely enough doesn't work
So it's not radient I guess.
Has anybody experienced this before ?

I find that .wav sometimes don't work for me(replacing it with an .mp3 usually fixes this). Never had it stop for no reason though.

Now it's getting scary
I renamed the teleport sound file to fiveminutes and changed the gsc and csv files accordingly.
I renamed the fiveminutes sound file to test
Before when I selected the fiveminutes sound (not the teleport sound I want) it played the sound.
Now that I renamed it to test and the teleport sound to fiveminutes, when I playtest the map (using the compiler) it still plays the fiveminutes sound (the sound before the change of name) !!???
I've searched my harddrive but their are only 2 fiveminutes wav's which, when played in mediaplayer, play the teleport sound.

Is this sound stored in the code of the map somewhere...don't think it is. Or is this a bug in the editor/compiler ?

My guess is a csv being read from an alternate source...
this is why I always test maps in IWD's and on a new installation of the game.

I found the problem. It's the compiler, it "saved" that sound somewhere.
I IWD'd the files and now it works. Never had a compiler problem before but I'll use the iwd now like you suggested drofder.
And the mp3's aswell, like Rezil suggested.
Thx guys for the reply.
