we use 2 phonon Mediaobjects in an audioplayer . we want same audio output (same volume slider) for both media objects . is it possible to do so in qt? if yes can you please give me an ex:?
Qt Code: 
  1. Phonon::MediaObject *mediaObject;
  2.     Phonon::SeekSlider *seekSlider;
  3.     Phonon::MediaObject *metaInformationResolver;
  4.     Phonon::AudioOutput *audioOutput;
  5.     Phonon::VolumeSlider *volumeSlider;
  6.  
  7.     Phonon::MediaObject *mediaObject_1;
  8.     Phonon::SeekSlider *seekSlider_1;
  9.     Phonon::MediaObject *metaInformationResolver_1;
  10.     Phonon::AudioOutput *audioOutput_1;
  11.     Phonon::VolumeSlider *volumeSlider_1;
  12.  
  13.  
  14.  
  15.     audioOutput = new Phonon::AudioOutput(Phonon::VideoCategory, this);
  16.     volumeSlider = new Phonon::VolumeSlider(ui->frame_2);
  17.     volumeSlider->setObjectName(QString::fromUtf8("volumeSlider"));
  18.     volumeSlider->setStyleSheet("border:none;background:none;");
  19.     volumeSlider->setGeometry(QRect(105,70, 141, 50));
  20.     mediaObject = new Phonon::MediaObject(this);
  21.     mediaObject->setCurrentSource(Phonon::MediaSource(musicpath));
  22.     connect(mediaObject, SIGNAL(aboutToFinish()), SLOT(enqueueNextSource()));
  23.     connect(mediaObject, SIGNAL(finished()),mediaObject,SLOT(stop()));
  24.     //connect(mediaObject, SIGNAL(aboutToFinish()),mediaObject,SLOT(play()));
  25.     Phonon::createPath(mediaObject, audioOutput);
  26.     volumeSlider->setAudioOutput(audioOutput);
  27.     ui->pushButton->hide();
  28.  
  29.  
  30.  
  31.  
  32.     audioOutput_1= new Phonon::AudioOutput(Phonon::VideoCategory, this);
  33.     volumeSlider_1 = new Phonon::VolumeSlider(ui->frame_2);
  34.     volumeSlider_1->setObjectName(QString::fromUtf8("volumeSlider"));
  35.     volumeSlider_1->setStyleSheet("border:none;background:none;");
  36.     volumeSlider_1->setGeometry(QRect(105,70, 141, 50));
  37.     mediaObject_1= new Phonon::MediaObject(this);
  38.     mediaObject_1->setCurrentSource(Phonon::MediaSource(musicpath));
  39.     connect(mediaObject_1, SIGNAL(aboutToFinish()), SLOT(enqueueNextSource1()));
  40.     connect(mediaObject_1, SIGNAL(finished()),mediaObject_1,SLOT(stop()));
  41.     Phonon::createPath(mediaObject_1, audioOutput_1);
  42.     volumeSlider_1->setAudioOutput(audioOutput_1);
  43.     volumeSlider_1->hide();
