Configuring Bluetooth headset to work with XBMC

[fedexp]

Hi,

Here is my setup details:

Raspberry PI - Model B (512MB RAM)
Xbian version - 1.0Beta 1.1
Overclocked - Yes, 950Mhz core
SD Card - Class 4, Transcend 4GB
Bluetooth Adapter - ASUS BT-211
Bluetooth headset - DEL BH200

So, I've been trying to setup XBMC to send audio to my bluetooth headset and video to hdmi - I've not found success yet. As a last resort, I wanted to post in this forum for help. This is what I've done so far:

1) Starting dbus service.
2) Installing bluetooth package (bluez util)
3) Installing alsa package.
4) Adding my bluetooth headset as a trusted device.
5) Configure asound.conf to include my headset.
6) Playing a test file on paired headset using aplay.

All I need to do now (according to guides on the internet) is go into XBMC ->Settings->System->Audio and configure my headset as a custom audio device. However, this is where I am stuck - no matter what I do, I do not get an option to specify a custom audio device - this option is not enabled at all. I just have Analog, HDMI and All, when I select Analog, I have no option to specify a custom audio device.

What do I do here? How do I setup up XBMC to send audio to my headset?
