To configure the driver, just do this (manually) in your 
/etc/modprobe.conf file:

#install snd-azx /sbin/modprobe --ignore-install snd-azx && 
/usr/sbin/alsactl restore >/dev/#null 2>&1 || :
#remove snd-azx { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; 
/sbin/modprobe -r --ignore-#remove snd-azx

# ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-azx
# module options should go here

# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0

# card #0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

The commented lines above are the default lines added by 
system-cofig-soundcard. If you have lines like those, either remove them 
or delete them. Once you do this, try probing the driver with 
/sbin/modprobe snd-azx, then check with /sbin/lsmod | grep snd. Now run 
alsamixer to configure the card volumes (in ALSA 1.0.8 this chanted 
slightly, you will have capture settins in a different "tab", to access 
them press F4 [F3 returns you to playback] or F5 [to see all controls]), 
when done simply press esc, and to store the values, restart the 
alsasound service with /sbin/service alsasound restart. All this as 
root, of course. Good luck.
