[Interest] Only buzzing sound while playing wav file through QAudioOutput

[Anisha Kaul]

Hi,

This time I tried playing a wav file, but I cannot hear anything else than
a buzzing sound.
Platform is windows if that matters.

This time the code is in main.cpp.

Please guide.
***********************************************************************************************

#include <QCoreApplication>

#include <QAudioOutput>

#include <QFile>

#include <QDebug>


int main(int argc, char *argv[])

{

    QCoreApplication a(argc, argv);


    QAudioOutput* audioOutpu;


    QFile sourceFile;

    sourceFile.setFileName("c.wav");

    bool p = sourceFile.open(QIODevice::ReadOnly);

    if (p == false)

        qDebug() << "no file";

    else

        qDebug() << "yes file";



    QAudioDeviceInfo d1;

    QList<QAudioDeviceInfo> l1 = d1.availableDevices(QAudio::AudioOutput);


    qDebug() << "======================================================";

    qDebug() << l1.first().supportedCodecs();

    qDebug() << l1.first().supportedChannelCounts();

    qDebug() << l1.first().supportedSampleTypes();

    qDebug() << l1.first().supportedSampleRates();

    qDebug() << l1.first().supportedSampleSizes();


    QAudioFormat desiredFormat1;

    desiredFormat1.setChannelCount(2);

    desiredFormat1.setByteOrder(QAudioFormat::LittleEndian);

    desiredFormat1.setCodec("audio/pcm");

    desiredFormat1.setSampleType(QAudioFormat::SignedInt);

    desiredFormat1.setSampleRate(44100);

    desiredFormat1.setSampleSize(16);


    QAudioDeviceInfo info1(QAudioDeviceInfo::defaultOutputDevice());

    if (!info1.isFormatSupported(desiredFormat1))

    {

           qWarning() << "Default format not supported, trying to use
the nearest.";

           desiredFormat1 = info1.preferredFormat();

    }


    audioOutpu = new QAudioOutput(desiredFormat1);

    audioOutpu->setVolume(1.0);


    audioOutpu->start(&sourceFile);

    qDebug() << "bbbbbbbbbb";


    return a.exec();

}

Output:
