Subject: Bluetooth Headset connection issue with PulseAudio

Hi All,
I am trying to connect my bluetooth headset to my Linux box using Pulse 
Audio. I am able to successfully run the pactl sink command but when I 
look at the debug log I could see the headset is connecting and 
disconnects immediately due to an error returning unknown connection 
handle in the SCO packet.

My test configurations:
Linux Kernel version : 2.6.30
Bluez version : 4.32
Pulse audio version:  0.9.14
Linux Distro: Ubuntu Jaunty 9.04

My BT Dongle: Gigabyte BTD02
HCI Ver: 1.2 (0x2) HCI Rev: 0x639 LMP Ver: 1.2 (0x2) LMP Subver: 0x639
Manufacturer: Cambridge Silicon Radio (10)

Pulse audio, pactl sink command output is as below:
btaudio~$ sudo pactl load-module module-alsa-sink device=btheadsetsudo: 
unable to resolve host btaudio
15

I am getting the following error in the kernel message:
hci_scodata_packet: hci0 SCO packet for unknown connection handle 45

Please find the log of "bluetoothd -nd":
bluetoothd[4127]: Unix client disconnected (fd=13)
bluetoothd[4127]: State changed 
/org/bluez/4127/hci0/dev_AE_2D_CC_AA_BB_14: HEADSET_STATE_PLAYING -> 
HEADSET_STATE_CONNECTED
bluetoothd[4127]: No matching connection found for handle 45
bluetoothd[4127]: telephony-dummy: device 0x2064d398 disconnected
bluetoothd[4127]: State changed 
/org/bluez/4127/hci0/dev_AE_2D_CC_AA_BB_14: HEADSET_STATE_CONNECTED -> 
HEADSET_STATE_DISCONNECTED

My asoundrc file:
btaudio:~$ more .asoundrc
pcm.btheadset {
type bluetooth
device AE:2D:CC:AA:BB:14
profile "auto"
}

Anyone has come across this similar issue? Any suggestions.

Thanks & Regards,
Benjamin
