from the man page ( man alsactl ):

NAME
        alsactl - advanced controls for ALSA soundcard driver

SYNOPSIS
        alsactl [options] [store|restore|init] <card # or id or device>

DESCRIPTION
        alsactl is used to control advanced settings for the ALSA
soundcard drivers. It supports multiple soundcards. If your card has
features that you can't seem to control from a mixer application, you
have come to the right place.

COMMANDS
        store saves the current driver state for the selected soundcard
to the configuration file.

        restore loads driver state for the selected soundcard from the
configuration file. If restoring fails (eventually partly), the init
action is called.

<edit>

FILES
        /var/lib/alsa/asound.state (or whatever file you specify with
the -f flag) is used to store current settings for your soundcards. The
settings include all the usual soundcard mixer settings. More
importantly, alsactl is capable of controlling other card-specific
features that mixer apps usually don't know about.
