gutsy + bluetooth-alsa + Motorola HT820

Hi, I've picked up a number of bluetooth devices recently, and I'm
interested in using it with my gutsy-installed laptop.

I've looked around and haven't found a decent step-by-step guide for
making this work. I can pair the device, but I can't get it to show up
as an option for aplay or gstreamer-properties. 

I've tried the steps in file:///usr/share/doc/bluetooth-alsa/build.html
but I can't get any sound other than a beep when the headphone is paired
and connected.

Here's what I get from aplay:
burner at phoenix:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: HDA Generic [HDA Generic]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

and a2dpd:
