Come on guys, this bug was reported almost 6 months ago and there is still no fix for that. Could you focus on it or at least provide a temporary solution. #5 doesn't work for me as well. I have here a Sony MDR-ZX750BN with Ubuntu 16.04 xenial presenting the same problem, it connects but no audio is played. If I use blueman-manager and try to change to A2DP mode, it provides an error message saying that it is not possible to make the switch and keeps the headphone turned off.
