Adding commands to shutdown and reboot

[utu]

1. How do you change audio volume settings?
2. How do you save volume settings if changed?

In addition to /etc/rc.local,
I use the alsamixer gui that comes up using alsamixer in a terminal window, to observe,
set and record most alsamixer settings. See the attached png.
This gui shows graphically all the audio settings.

I use the volume control applet on the lxpanel to change and/or mute the volume control.
