Playing Sound, Controlling The Volume, cacko1.23 Options

[speculatrix]

I have successfully played sound like this...

CODE

#include <qsound.h>

QSound soundSample(Resource::findSound("wave"));
soundSample.play();

However, I am trying to set the volume control.. I have tried everything I can find from googling, but no joy!

If anyone has any ideas, I'd be terrible grateful!

Here's what I have so far:[/code]
Config cfgSound("Sound");
cfgSound.setGroup("System");
int oldVolume = cfgSound.readNumEntry("Volume", 0);
cfgSound.writeEntry("Volume", 66);
int newVolume = cfgSound.readNumEntry("Volume", 0);
QCopEnvelope( "QPE/System", "volumeChange(bool)" ) << FALSE;
[/code]

the code runs but the volume doesn't change..

reading it and calling readNumEntry then writeEntry then readNumEntry reveals the new value is accepted, but the volume level doesn't change!
