    Hello,
    I am currently developping a QML application, and in a plugin I would like to play a sound (wave file).
    But there are several instances and only one sound can be played at a time. I am using Qsound to do this.

    @ QString lstmp=getenv("PROJECT");lstmp+="\recorder4.wav";
    if(!QSound::isAvailable()) qWarning("QMLCanvas error :QSound not available on this plateform");
    QSound::play(lstmp);@

    I did it with Phonon. But I tried to overload the system, ans send it every 100ms so I have the following error comming:
    QThread::start: Failed to create thread (Code d?acc?s non valide.)

    How can I test the availability of the system?

      can you try the following please (instead using the the static method):
      @
      QSound first("first.wav");
      first.play();
      QSound second("second.wav");
      second.play();
      @

        Hi again,
        using Phonon, I face a delemma:

        either I pu a local instance in the method called every time I needa sound to be played and the instance seems dynamically allocated, and my process size increase in memorry:
        @ //-------------------------------------
        //Local Sounds
        Phonon::MediaObject *lTmpmusic =
        Phonon::createPlayer(Phonon::MusicCategory,
        Phonon::MediaSource(lstmp));
        lTmpmusic->play();@

        Or I use a member in my class, but only the first sound is played
        @if(music!=NULL)
        {
        if(music->state()==Phonon::PlayingState)
        music->stop();
        music->play();
        }@

        Is there a way to have a self destructive instance when the sound is finished playing ?
        Or how to "restart" playing the sound when only one member instance is avialable?
