It would be nice if the master volume persisted during power off cycle.
Once such mechanism is in place it will allow to preserve various other user settings too.
If a configuration switch is added to select between Line-out and HP levels, it would be nice to preserve both volume levels separately, and also the switch setting.
Later, if there are many settings, a "factory reset" command will be useful to reset them all into defaults, in case user messed things up and is not sure what is going on.
