Where's a tutorial or at least a source where I can learn how to play samples in KDE?

Hi all,

I'm surely getting obnoxious with this, but it's the only thing that is 
missing. I'm referring to my project kisdnmonitor.

"Now" I'm implementing the audio stuff for VoIP, I'm using the arts C api. 
While in KDE3.1 I had crappy sound quality, now with KDE3.2 the quality has 
improved, the only problem is that whenever the caller speaks into his phone 
he hears himself, that wasn't happening with KDE 3.1. I guess that the mixer, 
internally mixes the microphone input with the speaker output, I'm not 
talking about echo.

I'm really desperate, since the only thing that is missing for the release of 
kisdnmonitor with VoIP support is the audio stuff and I'm stuck with the 
issue since some months and no one seems to be able to help me, nor I've 
found simple examples, besides the C API stuff, on how to program sound on 
KDE with it's server.

If you're interested you can get more information about the project on 
following links:

http://isdnserver.sourceforge.net
http://kisdnmonitor.sourceforge.net

Is out there some caritative sould that could help me?
