Good day: using Opensuse 12.3 with standard desktop kernel from repo,
pulseaudio under Gnome.
Steps to reproduce:
1. clean boot of machine.
2. USB Bluetooth adapter Belkin which works reliably
3. Issue command as root "hciconfig 0 sspmode 0" - this is essential
otherwise bluetooth device not recognized.
4. Open gnome sound settings from user menu; onboard sound device is
present, only one entry
5. switch on bluetooth device Samsung WEP 475
6. device is recognized and paired, an entry appears in PA list
7. about 10 sec later a second entry for the same BT device appears in
the
list
8. after playing with the windows sometimes the second entry will go
away
9. at least one of the entries will work and PA shows amplitude changes
registering for the input device
10. sometimes clicking the wrong one will cause Gnome settings window
to
crash, but BT and PA are still running and device is working and gnome
window can be opened again.
Clearly the multiple entries thing is not normal behaviour.
Might be a BT issue, or a PA issue, or a Gnome issue or other.
It's a tossup where where to start, can I rule out the BT side?
Can you specify which versions of BlueZ and PulseAudio you're using?
Also, please check:
a. which modules are loaded during the issue by doing "pactl list
modules" or similar.
b. which bluetooth devices BlueZ registers on D-Bus: "test-device
list"/"bluez-test-device list" or similar. You can alternatively use a
tool such as d-feet.
Cheers,
Mikel

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.
As you probably guessed, the traces you provide look good, no
duplicated devices there. I would thus assume it's a UI issue, you
might confirm this by using pavucontrol and checking whether the card
(representing the device) is listed twice or not.
Besides, when you say "7. about 10 sec later a second entry for the
same BT device...", is this happening only after you pair the device?
Or does the issue also reproduce every time the device gets connected
(without unpair + pair)?
Cheers,
Mikel
Thanks Mikel
My testing to this point has been that the device was connected
automatically having been pre-registered and paired.
So I deleted the pre-registered entry and re-paired the device. The device
entry behaved correctly when first paired, however when I left the
registration in place, unconnected the device and then reconnected it, the
duplicates reappeared.
In fact each time I selected an entry at random and clicked "test speakers"
it created a new entry. At one point I had 6 entries all working and all the
same device.
It certainly looks like a UI issue. I will contact the PA folks.
Thanks for helping me remove the BT side from the query list.
[CCing PulseAudio mailing list]
In the PA side, double check that you don't have duplicated instances
of module-bluetooth-device. There was an issue
(https://bugs.freedesktop.org/show_bug.cgi?id=57239) similar to the
one you describe, which should have been fixed for 3.0 (commit
41055145d7563c20fd58ed4b0a9b349c2363bb02).
Thanks Mikel
With about 6 entries in my Gnome PA window:
# pactl list modules | grep bluetooth
Name: module-bluetooth-policy
module.description = "When a bluetooth sink or source is added, load
module-loopback"
Name: module-bluetooth-discover
module.description = "Detect available bluetooth audio devices and
load bluetooth audio drivers"
Name: module-bluetooth-device
So there is only one bluetooth module loaded for the device even though
there are many devices listed in the window.
FWIW I recently upgraded from Opensuse 12.2 to 12.3, I don't remember
seeing this issue in 12.2.
I did not approach the PA folks on this yet, but I see that you have
cc'd the list and I will do the same.
Cheers
