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.
to change volume i just mess around with the LXDE pluginvolume.png
I have no experience with the png you show for a Volume Control applet.
The one I use is the standard lxpanel applet supplied with Knoppix.
If missing, thie applet I use may be added with
Right Click lxpanel>Add/Remove Panel Items>Panel Applets>Volume Control>Add
You might try that.
