sound. kdelibs-data wont upgrade

[David Morley]

i keep getting a message says sound server error cpu overload shutting down.
My 64bit system runs apps better in kubuntu than ubuntu so i am happier with 
it but kynaptic and apt-get even trying before post install won't let me 
upgrade the kdelibs-data;4;3 yada yada is this something that would help 
remedy my sound problem, and stop some errors that i get.  If so how can i 
force it to install.
