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 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1181106 Title: Failed to change profile to A2DP in 13.04 (Raring), 13.10 (saucy), and 14.04 (trusty) Status in Bluez Utilities: New Status in pulseaudio package in Ubuntu: Confirmed Status in pulseaudio package in Debian: Fix Released Bug description: I upgraded to 13.04 recently and my A2DP profile, which had been working great under 12.10 is suddenly gone. Neither my blueman applet nor the built-in bluetooth manager applet can connect my external bluetooth speaker to the A2DP profile. They can connect to the bluetooth device itself just fine. Steps I'm using: * using blueman, I can connect to the external bluetooth speaker and view the device in the devices listing * I can connect the device to the Audio sink and I get a message saying it is now connected and will "show in the PulseAudio mixer" * After connecting the external speaker to the audio sink, I can also see the device in the "Play sound through" listing in the Sound system control panel, but the icon has a circle with a line through it. * but if I right-click the device and choose "Audio Profile" from the context menu and try to select "High Fidelity Playback (A2DP)" as the new profile, I get an error message stating "failed to change profile to a2dp" I've already added "Enable=Socket" in /etc/bluetooth/audio.conf, without that I can't pair my headset. Now I can pair it, but I can't activate the A2DP profile. When I try to activate it, I see this message in my syslog : pulseaudio[2603]: [pulseaudio] module-bluetooth-device.c: Profile has no transport I tried the kernel 3.9.0 because of a sound problem with my soundcard, this kernel fixed my soundcard problem, but A2DP still doesn't work To manage notifications about this bug go to: https://bugs.launchpad.net/bluez/+bug/1181106/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
