I was playing with this a little more.

If I do

amixer -q sset Master mute


amixer -q sset Speaker unmute

It works! (mute the "Speaker" device, and unmute the "Master" device works
too.). I can't mute/unmute the same device.

It wouldn't be too hard to write a shell script to determine the current
state, and either mute the master, or unmute the Speaker. (With more work
you could find all the available devices[1] and unmute each one. Someone
may already have this.).

You could change the keybinding (in the lubuntu-rc.xml file mentioned in my
previous email) to execute your script instead of the amixer command.

I wrote something like that to toggle the mousepad. It's not too
