How to change system volume using qt
I would like to change system sound volume using qt.
I tried with phonon:VOlumeslider and audiooutput classes but no help , these classes seems to be control the sound volume of the music player of the application, but doesnt have control over system sound voulme.
Please advice Qt way to do so.
