Playing external SWF sound

I imported an SWF movie onto my stage and it plays an mp3. I also have a couple buttons in the imported movie, one to stop the sound and one to play the sound. The play sound, however does not work.

Frame 1:

Code:

---

tune = new Sound();

---

Frame 2:

Code:

---

tune.attachSound("comeFly");
stop();

---

and on the play button:

Code:

---

on (press) {
    tune.Start();
}

---

I've also tried _root.tune.Start(); as well as putting the first two frames together.

tune.Start();

try lowercase start

tune.start();

also make sure you added the linkage ID "comeFly" for the sound in the linkage dialog box.

I found this excellent tutorial on FlashKit. I was able to do everything I wanted and more.
