QAudioOutput doesn't work correctly. I hear only noise - c++

Question

my program capture raw data from microphone in QT.
QAudioRecorder* recorder = new QAudioRecorder();
QAudioProbe* probe = new QAudioProbe;
connect(probe, SIGNAL(audioBufferProbed(QAudioBuffer)), this, SLOT(processBuffer(QAudioBuffer)));
QAudioEncoderSettings audioSettings;
audioSettings.setCodec("audio/mpeg");
audioSettings.setQuality(QMultimedia::HighQuality);
recorder->setEncodingSettings(audioSettings);
qDebug() << "probe ritorna " << probe->setSource(recorder); // Returns true, hopefully.
//qDebug() << "" << recorder->setOutputLocation(QUrl::fromLocalFile("test"));
recorder->record(); // Now we can do things like calculating levels or performing an FFT
myAudioServer = new MyAudioServer();
myAudioServer->startServer();
In previous code I record audio and I start a Qthread for send audio via QTcpSocket.
void QtVideoWidgetsIssueTrack::processBuffer(const QAudioBuffer& buffer){
QByteArray byteArr;
byteArr.append(buffer.constData<char>(), buffer.byteCount());
QByteArray Data = byteArr;
qDebug() << myAudioServer->isListening();
QTcpSocket* myAudioClient = myAudioServer->getSocket();
qDebug() << myAudioClient;
qDebug() << "in processBuffer";
if (myAudioClient != nullptr) {
myAudioClient->write(Data, Data.count());
myAudioClient->waitForBytesWritten();
}
}
The method processBuffer take data from microphone and send it from server to client.
void MyThreadAudioTcpSocket::readyRead()
{
while (socket->bytesAvailable() > 0) {
//fare il play da QByteArray
// get default output device
QByteArray* yourSoundData = new QByteArray(socket->readAll());
QBuffer* buffer = new QBuffer;
buffer->setData(yourSoundData->data(),yourSoundData->size());
buffer->open(QBuffer::ReadOnly);
QAudioFormat format;
format.setSampleSize(16);
format.setSampleRate(22050);
format.setChannelCount(1);
format.setCodec("audio/mpeg");
format.setByteOrder(QAudioFormat::LittleEndian);
format.setSampleType(QAudioFormat::UnSignedInt);
QAudioDeviceInfo info(QAudioDeviceInfo::defaultOutputDevice());
if (!info.isFormatSupported(format)) {
format = info.nearestFormat(format);
qDebug() << "formato non supportato";
}
QAudioOutput *output = new QAudioOutput(format);
output->moveToThread(this);
output->start(buffer);
}
}
readyRead is where data arrive from socket server. I read all data from socket, I put it in Buffer, set QAudioFormat and I create QAudioOutput linked buffer and start.
Now as you can hear from this link wav file QAudioOutput produce only noise. Why?
