I am also having this same problem. EZAudioPlotGL are drawn as expected, Only simulator. below EZMicrophone Delegate Method doesn't woek. However, func microphone(microphone: EZMicrophone!, changedPlayingState isPlaying: Bool) is work.

func microphone(microphone: EZMicrophone!, hasAudioReceived buffer: UnsafeMutablePointer<UnsafeMutablePointer<Float>>, withBufferSize bufferSize: UInt32, withNumberOfChannels numberOfChannels: UInt32) 
func microphone(microphone: EZMicrophone!, hasBufferList bufferList: UnsafeMutablePointer<AudioBufferList>, withBufferSize bufferSize: UInt32, withNumberOfChannels numberOfChannels: UInt32)
Xcode: Version 7.3
Swift 2.2
EZAudio 1.1.5
iOS : iPhone6s(OS 9.2.1)

I've discovered that it only happens when the AVAudioSession category is set to AVAudioSessionCategoryPlayback. Please AVAudioSession category set to AVAudioSessionCategoryRecord. EZAudioPlotGL are drawn as expected.
