[MDR-XB950BT, playback] No sound at all (Bluetooth headset)

[Alec Larsen]

I am unable to get sound to play through my Bluetooth headset. For the first few seconds, the headset plays a random series of tones. After that, it remains silent. When it is set as the audio output, any application that tries to play sound freezes or crashes (including the built-in audio test option).
