Superdave's hack was to change a letter of the name of the bluetooth audio gateway device name in btagextmodule.dll so that it fails to open it and turn off redirection. BTAudio uses the bluetooth audio gateway's ioctls to tell the OS to turn the redirection on and off. I'm a little surprised that both hacks can't be combined without a problem, but it could make sense if the audio gw driver passes off/on requests thru that dll as well (tho i don't know why it would).
