Hi I'm working on karaoke app. It should record video with sound of a user singing a song. Lyrics and melody are are provided by app. With video recording everything was fine until I've added audio input to AVCaptureSession. Problem is with AVAudioPlayer that plays melody - it just stops when AVCaptureSession starts. I did not find any restrictions on that in Apple docs. Did anyone have experience with recording sound in AVCaptureSession simultaneously with playing sound via AVAudioPlayer?
