I wonder if the receive call, ring, is just a script or is embedded deeply in something else? You would think it would just be a case of changing how the ring tone is played.

Currently is just set to a specific output device, you would think you could hack that to output to ALL output devices. As I understand it, bluetooth headsets just show up as sound cards to pulseaudio, so you just need to get the ring tone player pointed at the "all output devices" instead of a specific one. But I have no idea what it uses or where its called, to play your ring tone.

It may also be they did this to save battery power, as presumably playing out of more than out sound card at the same time uses more power. Still, there really should be the option to choose especially as this is Linux after all.

I just wish mine would hurry up and arrive so I can have a look around at the filesystem to try to find how some of this stuff works.
