Play Sound File with C++ and Qt 5

How can I play a sound file using Qt 5 and C++? I have tried QSound but I am told it does not workin Ubuntu (my current Operating System) and I have heard of Phonon but the library does not seem to be available in my Qt Package.

Qt5

QFile inputFile;
QAudioOutput* audio;
inputFile.setFileName("/tmp/test.raw");
inputFile.open(QIODevice::ReadOnly);

QAudioFormat format;
// Set up the format, eg.
format.setFrequency(7600);
format.setChannels(1);
format.setSampleSize(6);
format.setCodec("audio/pcm");
format.setByteOrder(QAudioFormat::LittleEndian);
format.setSampleType(QAudioFormat::UnSignedInt);

QAudioDeviceInfo info(QAudioDeviceInfo::defaultOutputDevice());
if (!info.isFormatSupported(format)) {
    qWarning()<<"raw audio format not supported by backend, cannot play audio.";
    return;
}

audio = new QAudioOutput(format, this);

connect(audio,SIGNAL(stateChanged(QAudio::State)),SLOT(finishedPlaying(QAudio::State)));
 audio->start(&inputFile);

C++

Use BOOL PlaySound(LPCTSTR pszSound, HMODULE hmod, DWORD fdwSound);

#pragma comment (lib, "winmm.lib")
...
PlaySound(TEXT("recycle.wav"), NULL, SND_ASYNC);

Set SND_ option asSND_ASYNC.

PlaySound reference : MSDN

Anyway you can listen the audio.

Install the package sox that contains the utility play. Or you can use mplayer or any console media player. Then use QProcess to start playing sound file.

#include <QProcess>

.......

QProcess qprocess;
qprocess.startDetached("play",QStringList()<<"wav/alarm-clock-01.wav");

.......
