Hi there! I have a tiny, yet very annoying problem. I've installed a bluetooth headset on an intel iMac. The headset works, but the problem is when I try to play some kind of media file (.mpeg for instance) in Quicktime. It plays the sound directly to the headset, even though I have the sound preferences set to the default output. If I play a .mov it works normally. It also works if I play a the .mpeg in VLC player. It doesn't even help to remove the bluetooth device. It just causes the Mac to throw an error in. Can anybody help? I've searched all over the web to find a solution to this problem, but to no avail.
