Estoy ejecutando Kubuntu 13.10 en una computadora portátil Lenovo Thinkpad T430.
Tengo un altavoz Bluetooth.
Después de mucho solucionar problemas, logré conectarme al altavoz. bt-deviceinformes:
$ bt-device -l

Cuando me conecto al altavoz, reproduce un sonido acogedor. Cuando hago clic en "Audio Sink" en el administrador de Bluetooth (creo que es BlueMon), el altavoz reproduce otro sonido y aparece un mensaje de "Éxito" en el administrador de Bluetooth.
Pero el audio del bluetooth no aparece en ninguna parte de la configuración. No hay ninguna opción para dirigir el sonido al altavoz. Todo el sonido proviene de los parlantes de la computadora portátil y el altavoz bluetooth está en silencio.
Instalé pulseaudio y pavucontrol (con muchos otros paquetes relacionados con pulseaudio y bluetooth). Pavucontrol en la pestaña Dispositivos de salida muestra solo el dispositivo de audio principal, pero según las guías en la web, el audio bluetooth debería aparecer allí.
Entonces... Una vez que tengo el altavoz bluetooth conectado, ¿cómo dirijo el sonido allí?
Algunos volcados que pueden ser relevantes:

Para habilitar la detección de dispositivos de audio Bluetooth en Pulse Audio, debemos asegurarnos de haber cargado los paquetes de Bluetooth para pulseaudio (módulo-de-audio-pulse-bluetooth debería instalarse de forma predeterminada).
Elmodulo-bluetooth-descubrirluego es responsable de agregar un dispositivo de audio bluetooth como receptor (o fuente en modo HSP/Telefonía) a los dispositivos de audio conocidos.
Para cargar este módulo podemos emitir
pactl load-module module-bluetooth-discover
Para cargar siempre este módulo al iniciar el servidor de sonido pulseaudio, agregamos las siguientes líneas a nuestro /etc/pulse/default.pa(o a nuestro archivo personalizado basado en usuario ~/.pulse/default.pa, o ~/.config/pulse/default.parespectivamente, si este archivo existe):
### Automatically load driver modules for Bluetooth hardware
.ifexists module-bluetooth-discover.so
load-module module-bluetooth-discover
.endif

Yo tuve el mismo problema. Enhttps://wiki.archlinux.org/index.php/Bluetooth_headsetEncontré esto:
Nota: Es posible que el dispositivo esté apagado de forma predeterminada. Selecciona su perfil de audio (OFF, A2DP, HFP) en la pestaña "Configuración" de pavucontrol.
Después de seleccionar A2DP hubo sonido.
