The kde multimedia people can help you. On kde-multimedia at kde.org! There where 
big discussions what belongs to kde-core-devel@ and what belongs to 
kde-multimedia@ some weeks ago, better respect it...

To change the volume you probably have to rely on certain prerequisites. 
Either a running kmix, or using some kind of console programm like 
alsamixer...

The volume level is almost always something between 0 and 1. Its over 1 if you 
want to amplify but thats only relevant inside software, you want to change 
the hardware volumes...
