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!

you can use tkvol to change the volume from the command line. the code for tkvol is included in the zplayer source....
