My case is simple: I need to play a warning signal and want to make sure the user will hear it, so I want to check the system volume.

Update for Swift

    let vol = AVAudioSession.sharedInstance().outputVolume

The audio session can provide output volume (iOS >= 6.0). 

float vol = [[AVAudioSession sharedInstance] outputVolume];
NSLog(@"output volume: %1.2f dB", 20.f*log10f(vol+FLT_MIN));
