    Volume control in QtMultimedia?

    I developed a program for symbian that it should record and play raw audio data.
    The data are stored in a QBuffer and I use QAudioInput to record and QAudioOutput to play.

    But the volume of the output sound is very low.

    What can I do to increase the output volume?

    Maybe use this native sound engine:

    It should work with raw data according to this : http://doc.qt.nokia.com/qtmobility-1.2/multimedia.html

    set volume like this way :

    Code:
    player->setMedia(QUrl::fromLocalFile("test.raw"));
     player->setVolume(50);
     player->play();
    regards,

    I have only had opposite problems with too loud sounds. Maybe the volume of the device is low?
