Multiple Objects with same sound

I'm trying to attach a sound object to many projectiles. The projectiles constantly emit a windy sound so when they fly by the player, they make a whooshing sound.

In the constructor of the class representing the projectile I have:

OgreAL::SoundManager *soundManager;
soundManager = OgreAL::SoundManager::getSingletonPtr();
OgreAL::Sound *sound;
if (!soundManager->hasSound("9992"))
{
sound = soundManager->createSound("9992", "wind.wav", true);

}
else
{
sound = soundManager->getSound("9992");
}
snowBall->getSceneNode()->attachObject(sound);
sound->setRelativeToListener(true);
sound->setGain(50);
sound->play();


However I get the error:
An exception has been thrown!

Error #: 4

I think what it's saying is I'm trying to attach a single sound node to many different projectiles. Is there an alternative solution that would give me the same effect?

You would need to create multiple, unique instances that all source from the same sound file. OgreAL is smart enough to use the same sound buffer so this won't hog a bunch of memory, but you are not yet able to create more sources than your audio hardware allows.

Thanks for the help. That makes a lot of sense. I'm kind of new to Ogre, so I'm not sure how to do that. How do I source from a single sound file from multiple objects? Because I thought that's what I was doing with the original code.

In my mind the code says:
-attach a sound to an object
-If any other object needs that sound, just grab it and play

So how would I modify my code to fit your solution?
