Headphones automatically mute when plugged

Since I've upgraded to Ubuntu 16.04 LTS I have the following problem: When I plug in the headphones they are muted and to resolve this I have to un-mute the "speaker" in alsamixer, as seen in the image.

enter image description here

Is there any way of reverting it to the regular behavior?

Thank you in advance!


Edit this file:

/usr/share/pulseaudio/alsa-mixer/paths/analog-output-headphones.conf

Comment this 2 lines just putting a ; in front of the lines

[Element Speaker]
; switch = off
; volume = off

Restart pulseaudio:

killall pulseaudio
pulseaudio --start
