Right click on volume indicator in system tray -> Audio Volume Settings -> Audio Volume tab -> Output devices there find something called Built in Audio Analog Stereo (or something that represents your internal sound card) and there you will see under it Port = Speakers -> change it to Headphones and the headphones will work. There is some automatic switch in Maui pulseaudio missing that should be doing this (there was already a thread somewhere in the forums about it).
