Driver management like this is generally considered a user-mode task. 
You could write a small bus driver, and have it manage the creation of
your virtual audio driver.  That way, you could send a command to the
bus driver to do a "surprise removal", just like unplugging a USB device.

What's going to happen to applications that are currently using your device?
