There is an alsa utility to store the current settings of the alsa mixer
called /usr/sbin/alsactl, so running "/usr/sbin/alsactl store" will
store the setting and "/usr/sbin/alsactl restore" will restore them. The
settings themselves are stored in /etc/asound.state. 

I usually use "gamix" to control the soundcard mixer (which is different
in all cards - hard to give directions on how to set it correctly for
your needs).
