Successfully connected to a bluetooth speaker, but how do i direct sound there?
I'm running Kubuntu 13.10 on a Lenovo Thinkpad T430 laptop.
I've got a Bluetooth speaker.
After a lot of troubleshooting i managed to connect to the speaker. bt-device reports:
$ bt-device -l
Added devices:
[Samsung] W_Audio (5C:F6:DC:88:05:62)
$ bt-device -i 5C:F6:DC:88:05:62

When i connect to the speaker, it plays a welcoming sound. When i click "Audio Sink" in the bluetooth manager (it's BlueMon i think), the speaker plays another sound, and a "Success" message appears in the bluetooth manager.
But the bluetooth audio does not appear anywhere in settings. There is no option to direct sound to the speaker. All the sound comes from laptop speakers and the bluetooth speaker is silent.
I installed pulseaudio and pavucontrol (with a bunch of other pulseaudio- and bluetooth-related packages). Pavucontrol on the Output Devices tab shows only the main audio device, but according to guides over the web, bluetooth audio should appear there.
So... Once i have the bluetooth speaker connected, how do i direct sound there?
Some dumps that might be relevant:

To enable Bluetooth audio device discovery in Pulse Audio we need to make sure we had loaded the bluetooth packages for pulseaudio (pulseaudio-module-bluetooth should be installed by default).
The module-bluetooth-discover then is responsible to add a bluetooth audio device as sink (or source in HSP/Telephony mode) to the known audio devices.
To load this module we can issue
pactl load-module module-bluetooth-discover
To always load this module on startup of the pulseaudio sound server we add the following lines to our /etc/pulse/default.pa (or to our custom user-based ~/.pulse/default.pa, or ~/.config/pulse/default.pa resp., if this file exists):
### Automatically load driver modules for Bluetooth hardware
.ifexists module-bluetooth-discover.so
load-module module-bluetooth-discover
.endif
I had the same problem. On https://wiki.archlinux.org/index.php/Bluetooth_headset I found this:
Note: The device may be off by default. Select its audio profile (OFF, A2DP, HFP) in the "Configuration" tab of pavucontrol.
After selecting A2DP there was sound.
