    Qt c++ play sound on key press - stops working after a few seconds

    I'm making an apllication which needs to play .wav file when user type something inside QTextEdit. I made some code but after minute or less the sound stops, so I made silly workarround. After 30 clicks I invoke sound->stop(); and then the loop start again, that works, but it's not good, can you give better solution. Here is my code:

    int count = 0;
    bool MainWindow::eventFilter(QObject *o, QEvent *e){
        if(e->type() == QEvent::KeyPress)
            if(count == 30){
                count = 0;
        return false;
    (tipka is Phonon::MediaObject)

    what do you want to do?
    is it short beep that occurs when the user presses a key, or a longer one?

    you cant seek when the sound is in the stopped state, try omitting the seek(0) or use stop() instead.
