Mikel -

-----------------

$ pulseaudio --version
pulseaudio 3.0

-------------------

# bluetoothd --version
4.101

-------------------

# test-device list
00:0D:E6:6E:51:47 WEP475

-------------------

# pactl list modules

### this module is added after starting the Samsung device

Module #28
     Name: module-bluetooth-device
     Argument: address="00:0D:E6:6E:51:47" 
path="/org/bluez/455/hci0/dev_00_0D_E6_6E_51_47"
     Usage counter: 0
     Properties:
         module.author = "Joao Paulo Rechi Vita"
         module.description = "Bluetooth audio sink and source"
         module.version = "3.0"

-------------------

A small point to add to steps to reproduce:

11. with two entries showing in PA, shut down of BT device removes the 
latest added entry from the PA list leaving one entry for the device 
even though it is not active.
