AKClipPlayer playing in the middle of clip

I'm trying to make audio player and instead of using AKAudioPlayer which is taking too much ram on init, i'm using AKClipPlayer like that:

AudioKit.engine.prepare()
let clip = AKFileClip(audioFile: self.recorderAKAudioFile!)
self.player = AKClipPlayer(clips: [clip])
try! AudioKit.engine.start()
if AudioKit.engine.isRunning {
     AudioKit.output = self.player
                //set the time
    self.player?.currentTime = self.playPositionSeconds
    self.player?.play()
    runPlayerAnimations()
}

The problem is that audio is silent almost every time i run this code on long recording and it does not matter what play position i set. Is there a better way to play audio with specific starting time and not kill app with using all devices ram?
