I want to have a WAV file that plays in the background looping, it is ambient city noise like cars beeping etc....

here is the code i have used to put the sound in and it loads the file and runs the script but wont actually play the sound thru the speakers


sound background = "background.wav";
var_nsave background_handle;




background_handle = snd_play(background, 75, 0);


any ideas?
