UIImagePickerController AVAudioPlayer

When I open a UIImagePickerController, I can display the device's camera input stream.

But when I play an AVAudioPlayer with [player play] then the camera stops working.

How can I deal with that?

you can't because UIIMagePickerController is controlling the audio, you will need to use low level AVFoundation in order to do that.

checkout AVCam sample code how to record a movie and add the view as subview , that way you will stay in control of the audio and will be able to play audio.
