OK, so you need to make/break audio and not USB? That may be a hard
nut to crack.
Unplugging the USB connector seems to work. So why wouldn't a switch?
Newer PCs seem to sense when an audio connection changes.
One way of doing that is to use a phone jack similar to symbol D in
this schematic:

The tip breaks/makes a switch as the plug is inserted/removed. When
plug is removed the tip signal lines(s) get(s) connected to an unknown
"black box" circuit.

I love to cook with wine. Sometimes I even put it in the food.
