Okay, here's how to have an expect script check off that radio button
(requires expect to be installed of course):


#! /usr/bin/expect

spawn pacmd
expect ">>>"
send "set-default-source alsa_input.usb-Generic_FREETALK_Everyman_0000000001-00-Everyman.analog-stereo\r"
expect ">>>"
send "exit=\r"


If I tie that to a custom application launcher in my panel, it does check
the radio button and activate the mic. 

Now if I could tie it to some event triggered by plugging the usb headset
in, the immediate problem would be completely (if awkwardly) solved.
