[zhksteal@ArchZhKSteaL ~]$ alsactl --help
Usage: alsactl <options> command
...
Available state options:
  -f,--file #      configuration file (default /var/lib/alsa/asound.state)
...
Available commands:
  store     <card>  save current driver setup for one or each soundcards
                      to configuration file
  restore   <card>  load current driver setup for one or each soundcards
                      from configuration file
  nrestore  <card>  like restore, but notify the daemon to rescan soundcards

[b]Note:[/b]The new volume control won't appear imidiately! [b]Only after the first usage of the newly defined device (e.g. with speaker-test), should amixer sget Softmaster display the new control.[/b] Mixers that were already started before the first usage (like KMix) have to be restarted to adopt the changes. If the new control is still not there, try restarting ALSA or your PC.
[b]Removing a volume control[/b]
This task is not as easy at it seems, if you don't know the trick. If the correspondant part of the configuration file is just deleted and alsactl store has been executed after the usage of the device in question, the volume control won't disappear. [b]alsactl store stores the value of all controls (among them the softvol device) in /etc/asound.state and is most likely executed on every shutdown of your computer.[/b]
To make the volume control disappear finally, you [b]have to delete its values in /etc/asound.state[/b] or just the whole file (it will be recreated with default values on next reboot). After that, your computer has to be restarted once without the execution of alsactl store on shutdown. On Debian, this can be achieved by temporarily renaming /etc/rc6.d/K50alsa-utils (or similar). Pressing the reset button also works, but should be avoided.
