mhmh... intersting thought to split the audio output. i would have considered it a bug if any audio went through the speakers as long as the BT headset is connected. but then it's never wrong to have choices, is it?

would it be possible to have something like a "mixer application" direct different sounds to different outputs? like phone calls to BT, normal signals to the speakers and music from the media player to the wired headsets that for whatever weird reason you have inserted in spite of the BT headset?
