Answer 1

Now you can stop playing sound action by assigning key string for it then using removeActionForKey later

Sorry, this is Swift. But it can be ported to Obj-C.

let action: SKAction = SKAction.playSoundFileNamed("sounds/boom.wav", waitForCompletion: true)
self.runAction(action, withKey:"die-sound")
// later you do:
self.removeActionForKey("die-sound")

I have tested successful
