Disable / mute microphone from command line
Googling suggested "osascript -e 'set volume 0' " but that doesn't work.
I know I'd found this before... some command-line utility that had something to do with audio, mixers, whatever, but I forgot to keep it somewhere I could find it. I did find references to writing an AppleScript app, but that won't work here. I'm specifically looking for a command that comes with the OS that can be run in a bash shell.

SYNOPSIS

DESCRIPTION
ossxmix is a GTK+ based mixer applet that is used to display the mixer settings of physical and virtual audio devices. There can be several

certain functions on the speakers or set various device characteristics.
OPTIONS

-d<dev#>
Display only mixer device dev#. If this option is not given then ossxmix will display all the mixers available on the system.
-x Hides the "legacy" mixer controls.
-w[value]
Make the mixer slightly wider on the screen. This option affects only the selection boxes and peak meter LED bars. In most cases
this option is not required. The value can be between 1 (default) and 4.
-n[value]
Make the mixer slightly narrower than normally. This may be necessary if the mixer is wider than the screen. The value can be 1
(default) or 2.
-g[w:h]
Start ossxmix window with dimnesions w:h.
-b Start in background.
-S Do not try to place an icon in the system tray.
NOTES
o ossxmix without the -d parameter shows all the currently enabled mixers.
o Standard gtk toolkit options like --display are available as well.
