hci_scodata_packet: hci0 SCO packet for unknown connection handle 1

I'm running Ubuntu Hardy, so I have a nice bleeding edge installation of
kernel and bluez tools.  I am trying to get a Jabra headset to work but
it's just not happening for me.  I plug in the dongle and get the little
bluetooth applet showing in my taskbar.  My headset also beeps when this
happens.

lsusb reports:

lsbusb -v reports:

I believe it's all paired up nicely:

$ hcitool con
Connections:
	> ACL 00:1A:45:1B:19:89 handle 11 state 1 lm SLAVE AUTH ENCRYPT SECURE 

I follow the steps in http://wiki.bluez.org/wiki/HOWTO/AudioDevices but
when I try to play something with:

$ sox /mnt/mp3/bad_mouth.wav -t wav -c 1 - | aplay -D plug:bluetooth
sox wav: Length in output .wav header will be wrong since can't seek to fix it
Playing WAVE 'stdin' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono

I hear nothing and the dmesg/console log shows:

[ and on and on and on ]

Anyone got any advise?

Thanx,
b.
