Audio emitter issue

I'm having a bit of a problem with creating sound with an audio emitter. I have created my own sound of enviornmental noise and wish to put it into my mission. Here are the steps I took to make the sound appear in my game. First I put the sound into starter.fps/data/sounds/bg_noise.wav. This is obviously the folder where all the sound goes. I then started up my game and created a new audio emitter close to the ground. I went into its atributes and went to media > filename. I, of course, told it to go to starter.fps/data/sounds/bg_noise.wav. I then hit "apply" and saved it. I then exited and rebooted the mission and when I go towards the spot (I am sure the speakers are turned all the way up and there is definitely volume), but I can't hear anything. There is just no noise at all. I have tried creating a brand new mission and putting a sound that came with the torque SDK in an audio emitter, and it works perfectly. But whenever I use my own sounds it doesn't seem to recognize them. Thanks for any replys. :)
