Stoping a sound as an action on a node with a key in SceneKit

I've written a function in SceneKit that plays background music as an action on a node with a key so I could stop the music playing using the key

I have a global variable so I can call to stop the action from anywhere in the class, (by the way this is SceneKit not SpriteKit, I am still using Swift as a language though)

var musicPlayingAction = SCNAction()

however nothing stops it, either forKey or removeAllActions as in...

This does nothing

scnScene.rootNode.removeActionForKey("bgMusicKey")

So I try a higher level and drill down, killing all actions either on the scene, the view or the node (depending on where I attach the sound action).

self.scnView.scene!.rootNode.removeAllActions()

still nothing...

Even if I run the sound action on a specific node and try to kill that.. you guessed it nothing or should I say the music is still playing.

This is the function

func playMusic() {
        if game.state == .Playing {

            let music = SCNAudioSource(fileNamed: "art.scnassets/Sounds/BgMusic.mp3")!

            music.volume = 0.3;
            music.loops = true
            music.shouldStream = true
            music.positional = false
            musicPlayingAction = SCNAction.playAudioSource(music, waitForCompletion: false)
            scnScene.rootNode.runAction(musicPlayingAction, forKey: "bgMusicKey")
   }
}

The Action works as in the music plays but it will not stop.

Is it even possible to stop an AudioSource as an action, I know you can stop Actions with a Key, although this is the first time I have tried to stop an audio SCNAction (note not SKAction) with a key???

Any ideas appreciated, thanks.

if you add sound as an action to node you can remove this action with key , if you add sound as audio player you can remove it using remove a yourNode.removeAllAudioPlayers()

Solved!

Removed the Action forKey...

Split my game up into scenes, added a game state for each scene, then loaded background music dependant on state & scene.

Thanks for your help, much appreciated =)
