Initialize with numChannels = 2 fails to start

[plavunov]

Hi,

With numChannels = 1 works properly, with 2 channels doesn't work (app force quits on start)

I'm using iOS

just simpley replace code follow may be works, or there may be some issues that haven't been encountered yet

outputFormat = audioEngine.outputNode.outputFormat(forBus: 0)

//        outputFormat = AVAudioFormat(
//            commonFormat: .pcmFormatFloat32,
//            sampleRate: Double(sampleRate),
//            channels: AVAudioChannelCount(nChannels), interleaved: true)!
