I recently got a docking station for my 2008 13in macbook. When I dock it, the headphones jack automatically connects to my speakers. The problem is that I often use my Stereo bluetooth headphones for editing music so not to disturb others with repetitive playing. But for some reason, it won't allow a connection to my headset while something is plugged into the headphones jack. If I go to sound preferences and select the headset in the 'output' tab and go to play music, iTunes just freezes up and requires a force quit. Any ideas what might be causing the conflict? When nothing is connected to the headphones jack, the bluetooth headset connects without problems.
