just like with any other audio device. PulseAudio doesn't have any
special Bluetooth API, you just play and record audio using the normal
stream API. A new sink and source will be created for the headset when
RING and CKPD are ignored by PulseAudio, so you can't currently get
notifications about those, unfortunately.
