sound missing after upgrading to kde 3.2

[James Ng Yuen Sum <james_nghk_debian@yahoo.com.hk>]

Hi,

       I have upgraded to kde 3.2 from kde 3.1.4 using debian packages 
through apt-get. However, my sound is missing.
I have installed the packages arts, but I am using alsa as the sound 
system. On the kde 3.1.4, I also do the same, but no problem. The 
problem still exist if I upgrade the alsa-base to the newest version in 
debian package. (I just run as "apt-get install alsa-base alsa-utils, no 
recompile the kernel...). And my kernel is 2.4.23.

       Any suggestion?

Regards,
James Ng
