iPhone volume changed event for volume already max
<p>I'm using </p>

<p>AudioSessionAddPropertyListener(kAudioSessionProperty_CurrentHardwareOutputVolume,
                                    audioVolumeChangeListenerCallback, self);</p>

<p>to detect volume changes so i can take a picture with the volume rockers but if the phone is already at 100% i don't get an event. Is there a way to detect volume rocker pressed when the volume doesn't actually change?</p>
