"Thus you can use BT headset with applications which support the output configuration to specific alsa device (specified in ~/.asoundrc) [b]. If your application does not allow this kind of configuration you can also try to set the default alsa device to your BT headset too. This will help of course only if this application sends the output to alsa."
I think it's not possible to use it as how you expect.
I don’t really understand why you need to use pulseaudio for this purpose (as some people in this thread mentioned). I had a similar issue with an on-board sound card and an external headset that was plugged in via usb and recognized as a separate sound card. I wrote a simple udev rule (1 line) that switched the symlink /etc/asoundrc to two prepared asoundrc files in one of which the headset was the default device and in the other the on-board sound card. So if the headset was plugged in it was used exclusively and the other way round. :) Ed
