Using vibrate and AVCaptureSession at the same time

Question

I'm trying to vibrate the phone while recording video, but I'm finding that AudioServicesPlaySystemSound(kSystemSoundID_Vibrate); doesn't play nicely with AVCaptureSession. Is there any other way to vibrate the phone or am I stuck with losing the vibrate function while recording video?

I would think vibration would negatively affect the quality of the captured video. This could be why it's disabled. — picciano, May 07 '13 at 20:03
@picciano It's not just vibrate though, its any system sound — Eric, May 13 '13 at 17:13

You probably need to set the audio to mix with other, I found this useful:

- (void)setupAudio {
    [[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayback error: nil];
    UInt32 doSetProperty = 1;
    AudioSessionSetProperty (kAudioSessionProperty_OverrideCategoryMixWithOthers, sizeof(doSetProperty), &doSetProperty);
    [[AVAudioSession sharedInstance] setActive: YES error: nil];
}

from here
