Modify phonon sound volume :

Sil20

Hi,
I am developping on QT4.8.4, qtQquick 1.1, and I devellopped a sound player plugin.
I need to be abble to modify the sound volume dynamically, but I cannot found any working solution.

I am using Phonon mediaplayer object like in the example below

@ qreal lVolume=aVolume;
if (lVolume<0) lVolume=0.0;
if (lVolume>1.0) lVolume=1.0;

Phonon::MediaObject * lMediaPLayer=globalPhononSoundLists.value(lstmp);
////To DO : Modify sound Volume
qDebug()<< "SdcnSoundMediaPlayer::setVolumeSoundEffect: Not functionnal Yet :"<<lVolume;@

Is there a solution to do so?

Congratulations to our 2022 Qt Champions!
