Hallo
Habe die Lösung im Netz gefunden. Vermutlich hilft das für andere, welche die gleiche Frage haben.
This installation procedure also applies for Ubuntu 16.04.
Make a new file
sudo touch /etc/bluetooth/audio.conf
Add these lines inside. Do not change anything. The order is important.
[General]
Disable=Socket
Disable=Headset
Enable=Media,Source,Sink,Gateway
AutoConnect=true
load-module module-switch-on-connect
Now you will have to edit the file /etc/bluetooth/main.conf. Change the contents to this.
# Restricts all controllers to the specified transport. Default value
# is "dual", i.e. both BR/EDR and LE enabled (when supported by the HW).
# Possible values: "dual", "bredr", "le"
ControllerMode = bredr
If you have just one Bluetooth toggle and you switch from computer all the time, change this line too. Change the code to this.
# AutoEnable defines option to enable all controllers when they are found.
# This includes adapters present on start as well as adapters that are plugged
# in later on. Defaults to 'false'.
AutoEnable=true
Let the magic of rebooting be on your side. So reboot.
Enable pairing on your headphones.
Go to the Bluetooth icon, enable bluetooth and connect to your device.
Go to the sound icon (bottom right) and select your device.
See that the Output profile is High Fidelity Playback (A2DP sink). MUCH better sound than the other setting Headset Head Unit (HSP/HFP). As long as you do not see this headphone in your sound settings, you guessed it, something is wrong. And in Bluetooth nothing seems that simple. Then you can start Googling. I suggest the Arch Linux guide as a start.
When all is working, do close this window as it will be glitching the music since it is scanning for other bluetooth devices.
When you have been trying to add the Bluetooth device for a while, REMOVE IT and try again. That seemed to work for me.
