[Adil ALPMAN]

Dear Kubuntu Users;

I use creative SB-5.1-VX souncard and my lspci output is on 
http://pastebin.com/7K3W6gSL  address and my system has just updated 
with synaptic but when i start and login to my system and when i logout 
i just hear a noise... any sound... :( can anybody help me?

On the other hand i dont know which sound system that i use on my system 
(alsa or pulse audio or something like that...) Can anybody help me how 
can i know which one i use and how can i change my sound system from one 
to another one?

Sincerely...
