           Summary: Bluetooth headset pairing broken if pulseaudio is not
                    restarted

          Severity: normal
    Classification: Unclassified

           Version: unspecified
         Component: core
           Product: PulseAudio

I cannot get my headset to work with net-wireless/bluez-5.21-r1,
media-sound/pulseaudio-5.0-r2, 3.14.14-gentoo and Gnome 3.12.

The bluetooth subsystem refuses to recognize the audio profile: a2dp-sink.

I opened a bug to Gentoo and after investigation here is the outcome. I needed
to restart pulseaudio in order to bluez to make the connection. Here is the
steps I followed to debug this:

The problem:

And here is what I am getting in bluetoothctl:

Then, here I restarted pulseaudio with pulseaudio -k and then tried to connect:

    0000111e-0000-1000-8000-00805f9b34fb
[bluetooth]# 

And now the device is connected properly.

I shouldn't have to restart pulseaudio in order to make this working. Seems to
be a pulseaudio issue. My version of bluez is 5.21.
