I just wanted to know how to make sound come out of my built in powerbook's speakers and my external ones... that'd have a pretty sweet effect. I figured it would come with a software solution so I posted it here. Note: I saw the other thread about this, but nobody knew a way to do it without USB speakers. Anybody know of an app maybe? Like those 'alarm' apps for laptops will disable the headphone jack when they go off... maybe something similar to that.
