I'm trying to use an LG HBS700 Bluetooth headset with my laptop (Lenovo ThinkPad X1 Carbon running Xubuntu 12.10). I'm able to successfully connect the headset using the Blueman program, but when I go to pavucontrol, all I see under the "Output Devices" tab is "Speakers" and "Headphones", neither of which work with the headset.
I've tried setting the headset to both "Audio Sink" and "Headset service", but neither worked.

When I hit up or down, the volume OSD changes but the actual sound level doesn't. In pavucontrol, I don't see any volume settings changing, for the Bluetooth headset, for the speakers/headphone jack, or for an individual program.
