I have a Dell inspiron 7520 laptop with Ubuntu 16.04 LTS installed. When I try to connect my beats 3 bluetooth headset via bluetooth settings, it prompts a message saying:

connection failed. 

I tried to connect it with bluetooth manager software as well. But still cannot pair with the device. It identifies the device but fails to pair.

After issuing the command:

sudo pactl list short | grep blue -

The result I got was

7   module-bluetooth-policy     
8   module-bluetooth-discover       
9   module-bluez5-discover

Any suggestion. Please note that I recently switched to ubuntu from windows and the device was working fine with windows.

  • Please edit the question to include results from terminal for pactl list short | grep blue – Jeremy31 Jul 17 '17 at 11:35
  • Try using terminal bluetoothctl then scan on you should see a list of devices that are in pairing mode, find the MAC address of the audio device and try pair followed by the MAC address exactly as displayed in terminal – Jeremy31 Jul 20 '17 at 21:25
  • I had the same problem in Ubuntu 18.04 derivative with Powerbeats Pro; requirements section of this page helped me to solve. wiki.debian.org/BluetoothUser/a2dp – emre can Nov 9 '19 at 1:35

Try executing the following commands:

sudo apt install pulseaudio-module-bluetooth
sudo killall pulseaudio
sudo service bluetooth restart

Then, try to connect your device again using Blueman (Bluetooth Manager).
