If I run the following command after docking amixer --card 1 sset 'Speaker+LO' 100% the sound starts working. Unfortunatly I have to run this command every time I am docking the system to the docking station. Furthermore there is specific volume slider is not shown in the audio setttings of Unity. So this command could only be a temporary workaround... The internal speakers and the headphones jack of my laptop does not have these problems. It would be really nice if the audio output of the docking stations stays unmuted, when i connect the laptop to the docking station. Maybe this bug is related to https://bugzilla.redhat.com/show_bug.cgi?id=1101386, but the workaround proposed there does not work for me.
