store the state of the n'th card (starting from zero) in a file called
foobar: alsactl -f foobar store N
restore the state of the nth card (starting from zero) from a file
called foobar: alsactl -f foobar restore N

a properly configured system does this for all cards at system
shutdown and at boot time.

my script allows more specific kinds of setup to be done without any
reference to any existing state.
