Adding QTPLUGIN += qtaudio_coreaudio qtmedia_audioengine  makes it start up...  

After that it is crashing in AudioRecorder::ProcessBuffer() because AudioLevels.count == 0.
Probably should have a Q_ASSERT(audiolevels.count != 0) there...

I moved a bit of code from AudioRecorder::updateStatus, line 153, to a new method "initializeAudioLevels", 
and called it from the constructor and also from case QMediaRecorder::RecordingStatus:, and now I can record files....


void AudioRecorder::initializeAudioRecorder()
       if (audioLevels.count() != audioRecorder->audioSettings().channelCount()) {
            for (int i = 0; i < audioRecorder->audioSettings().channelCount(); ++i) {
                QAudioLevel *level = new QAudioLevel(ui->centralwidget);

i can email you a patch file if you like.
I would be willing to contribute a patch directly, but I'm kind of intimidated by getting set up with gerrit and all..
