Oh, heck yeah! You just connected the phone to the PC via Bluetooth, and the PC works as a BT speaker! Great stuff! Thanks for the tip, @aerror, @magitian, @ehrenschwan :)

@forteller I don't know how or why it worked but I recently connected to my Linux PC with bluetooth for something else and it just played audio on my PC.

@forteller have not tested, but seem relevant https://github.com/rgerganov/shanocast
