AVPlayerLayer pauses currently playing audio

Question

I have a ViewController which I add an AVPlayerLayer to have a video background. For that I use AVPlayerLayer and add it to the view's layer. If I have Spotify or anything else playing audio playing while opening that ViewController the PlayerLayer pauses it.

How can I end this behavior?

I create my layer like this:

lazy var playerLayer:AVPlayerLayer! = { 
    var playerLayer:AVPlayerLayer!
    if let src = NSBundle.mainBundle().pathForResource("Untitled", ofType: "mp4") {
        playerLayer = AVPlayerLayer(player: AVPlayer(URL: NSURL.fileURLWithPath(src)))
        playerLayer.frame = self.view.bounds
        playerLayer.backgroundColor = nil
        playerLayer.opaque = true
        playerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill

        playerLayer.player?.muted = true

        self.view.layer.insertSublayer(playerLayer, atIndex: 0)
    }

    return playerLayer
}()

As you can see Ive tried with setting the muted property to true, but it doesnt work.

The other apps' audio is interrupting yours.

You need to create an AVAudioSession and set the "mix with others" option.

try? AVAudioSession.sharedInstance().setActive(true)
try? AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback, withOptions: .MixWithOthers)
