Ok! As I thought, you haven't named the sound instance, and this is furthermore complicated by the tweens you have on that movie clip.
In the newest.fla, select the first keyframe of your sound layer, and in the Instance panel, add the name
sound in the name box, under the behavior box. It doesn't suffice that the movie clip be named sound, each instance you'll be referring to, needs to be named.
Once it's done on the first keyframe, because of your tweens, you'll have to repeat this in the other 2 keyframes you have on that layer. Repeat the instance's naming process above on keyframes 20 & 194.
Now in frame 124 of your music.fla, change your script:
on (release) {
stopAllSounds ();
}
on (release) {
loadMovieNum ("onlyone.swf", 8);
}
on (release) {
unloadMovieNum (6);
unloadMovieNum (7);
}
To the following:
on (release) {
_level0.sound.gotoAndStop(6);
stopAllSounds ();
unloadMovieNum (6);
unloadMovieNum (7);
loadMovieNum ("onlyone.swf", 8);
}
Guess you'll have to change your scripts on buttons 2 & 3 in a similar manner.
A few extra notes on all this:
If you allways loaded a soundtrack movie on the same level, level 8 for instance, there would be no need to unload the previous movies loaded, since loading the new one would simply replace the old one... This would simplify your script!
Can't tell how you've set up each individual tune movie itself (like stop actions & stuff!), but it might be of no use to unload other levels anyways... When unloaded, each tune does have to reload each time the user presses that selection, rather than just play (since it's in the user's cache), if he's made that selection before.
One final problem, you may not have realized, is that, while listening to The Only One, for example, if I press the headphone button, the main movie's sound track will start playing again over the other tune, eventhough your icon seems disabled.
You may want to set a variable, when an another sound is playing on another level, to really disable the main soundtrack.
We can get into a way of doing that later, if you're interested!
PS: Nice work!
