Comment 0 for bug 893611

I'm having a rather strange problem with the audio jack on the docking station. Using the headphone jack the external speakers work fine. When no speakers are plugged in the integrated speakers work. But when I plug in the speakers into the docking jack the integrated speakers get muted, but no sound comes from the external speakers.
