Bluetooth audio fails on 64-bit architecture

Bug #1169776 reported by Steve White
This bug affects 3 people
Affects Status Importance Assigned to Milestone
bluez (Ubuntu)

Bug Description

* Headset works fine on 32-bit machines under Ubuntu 12.04, 12.10
     (Samsung NC-20, Dell D420)

* Same headset pairs, but fails to do audio on a 64-bit machine, Ubuntu 32-bit or 64-bit 12.10 or 64-bit 13.04
    (Lenovo S206 with AMD E1-1200)

AGAIN: it fails on 64-bit *machines* regardless of the Ubuntu version,
and works on 32-bit machines.

* At first sometimes I see the hardware in the Sound Settings.
  but only hear some tinny, scratchy sounds briefly.
  Then the device disappears from the Sound Settings. Re-starting bluetooth has no effect.

On a working system, see syslog lines like
    bluetoothd[825]: /org/bluez/825/hci0/dev_<bluetooth-id>: fd(32) ready
    bluetoothd[825]: Audio connection got disconnected

But on the non-working systems, I don't see such bluetooth lines at all (I presume due to the logging level)
Anyway, no *errors* are showing, after pairing with the headset. The audio just doesn't work.

Please advise how to debug.

(Of course I don't know if the blame lies with the Bluetooth software or with PulseAudio, and of course I don't care.)

Please fix this soon! I have been using this on a daily basis, and need to move to a newer machine.

This bug is being reproduced in Xubuntu too and we are currently in 2015.

Distributor ID: Ubuntu
Description: Ubuntu 14.04.1 LTS
Release: 14.04
Codename: trusty
Arch: x86_64

Today I've received an update for bluez and pulseaudio but it seems to keep failing. I'm using a Plantronic ML18 headset recognized as PLT_ML20. When I pair the device and make the audio sink the device is not listed in pulseaudio device list.

I think is a bug from Blueman.
Could you check this issue? Is very frustrating to swap to another SO just for use several communications tools.

Thank you
