how to add sounds to games

[Alexander Semke]

Hi,

in Knights I'd like to add some sounds for moves, checks and mates. How is 
this is usually done in KDE games or in KDE applications in general?

On openSUSE I see couple of notification sound files /usr/share/sounds/KDE-*  
and /usr/share/sounds/freedesktop/*. I could maybe use some of them but I'm 
not sure they are available everywhere. Is there any set of "default sounds 
for games"?

Thanks and Regards,
Alexander
