Just hooked up my new ProMedia 2.1 speakers and discovered the same problem. Unable to use both inputs simultaneously. I'm returning the speakers. I'm not going to plug and unplug jacks between my TV and my computer (in the den) whenever I want to use one of them. My guests aren't going to know to do this. I also have the previous version of the ProMedia 2.1 (from 2008) setup in my office. I have both my desktop PC and laptop PC connected and can play audio from either one without fiddling with jacks. Why fix what's not broken? And what's with the white spotlight LED on the front of the speaker, shining in your face? My older set has a soft green LED... and has a power switch.
