Gnome 3.16.2 Sound bug

After a

#sudo zypper dup

I found bug in Gnome when I plug the headphones the sound is muted and when I unplug them they became muted again, so I have to change the volume level every time I use tem.

And I also found that the mute button on the keyboard only mutes the sound it doesn’t unmute, which I don’t think it’s the default behaviour of Gnome because on Antergos/Arch and Fedora it doesn’t behave that way.

Is any one else experiencing the same bugs?

After another upgrade the problem is gone.
