This seems to be a bug in either ALSA or KDE, as I've had the same 
problem. Workaround : Start Konsole. Set LD_PRELOAD to the full path to 
the ALSA library, ex. "export LD_PRELOAD=/usr/lib/libasound.so.2.0.0". 
Then start kcontrol. However,  all it will show is "ALSA Device", so 
you have to try all the devices that appear. For my SB Audigy, it's the 
second device, but yours may be different. 

If any ALSA developer sees this, it would appear that there is a problem 
checking the symbol versions. The following appears if kcontrol is 
started without LD_PRELOAD set:

gsocker@linux:~ > kcontrol
gsocker@linux:~ > ALSA lib dlmisc.c:97:(snd_dlsym_verify) unable to 
verify version for symbol snd_config_hook_load
ALSA lib conf.c:2561:(snd_config_hooks_call) symbol snd_config_hook_load 
is not defined inside (null)
ALSA lib conf.c:2968:(snd_config_update_r) hooks failed, removing 
configuration
handle==0

This is with ALSA dated May 20, 2002 (CVS version).
