Comment 44 for bug 1181106

Solution that works for Ubunut 14.04 64bit on Thinkpad Edge 13 (not sure which specific model, has AMD Neo K325 CPU) and Jabra BT620s:

1.) backup your /etc/bluetooth/audio.conf

2.) create an empty /etc/bluetooth/audio.conf —> eg "sudo touch /etc/bluetooth/audio.conf"

3.) after reboot/start of the computer, start blueman-manager and add your bluetooth A2DP —> if your are tailing /var/log/syslog, it will state it failed to switch to a2dp

4.) restart bluetooth with "sudo /etc/init.d/bluetooth restart"

5.) again add A2DP profile in blueman-manager

6.) reset/restart/whatever_this_command_actually_does pulseaudio with "pulseaudio -k"

7.) in /var/log/syslog you will notice that an audio device <your_bluetooth_headset> was added with profile A2DP

8.) set the default output device in pavucontrol to your bluetooth headset
