have you tried
that should load the module for a SoundBlaster Live.
but here's what I do
Edit /etc/rc.d/rc.modules and look for the sound card section for this...
# Sound Blaster Live support:
You'll need to uncomment it if it isn't already, then either reboot, or run the command
after that you'll need to su to root, and
chmod 666 /dev/dsp*; chmod 666 /dev/mixer*
and you should be good to go.
