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! |
