you need to find the module the sound card is using that you DO NOT want to 
load, and black list it. 

lsmod will give you a full list of modules you are running, piping it to grep 
will give you searching abilities.  However, running the following as root 
will give you a text file to look through:
lsmod > /root/modulesrunning.txt

view that file in an editor like kedit, kate, vi or less whatever you like, 
and look for modules that have a name like the brand of card, or "snd" around 

For example "lsmod | grep snd" produced the following on my dell:

snd_hda_intel          20116  1
snd_hda_codec         164608  1 snd_hda_intel
snd_pcm_oss            47360  0
snd_mixer_oss          19584  1 snd_pcm_oss
snd_pcm                84612  3 snd_hda_intel,snd_hda_codec,snd_pcm_oss
snd_timer              25348  1 snd_pcm
snd                    58372  8 
soundcore              11232  1 snd
snd_page_alloc         11400  2 snd_hda_intel,snd_pcm

From the looks of it I'd say "snd_hda_intel" is the module that's driving my 
HD sound card.
(the column on the far left is the module or driver, the list of modules after 
the two number columns is the list of modules the module on the far left 
depends on.  I can't remember what the two number columns mean at the 

the module for SB Live! cards I believe (I may be wrong) has "live" in the 
name.  Anyway, once you find out what module you do not want to have loaded, 
go to /etc/modprobe.d/ and edit the "blacklist" file like so:

vi /etc/modprobe.d/blacklist
kate /etc/modprobe.d/blacklist
and add a line that starts with "blacklist" has a space and then the module 
name you DO NOT want to have loaded.

Reboot and see what happens.
You can also check kmix to see what "Master Channel" its using.  Right click 
on the little speaker icon in the system tray, and click on "Select Master 
Channel" if you have more than one sound card, like when you have a voice 
modem and a sound card, select the sound card module from the list and click 

Hope some of this helps.

See Ya'
