So currently I am using a plantronic USB headset which I think is giving me great sound, much better then the nonUSB Icemats I used to use. I recently got some logitech X-230 speaks and a sub. My question is, how do I setup my computer so that I don't have to manually unplug the components I want to use whether it be the speakers or headset. I am using a Audigy sound card and I am assuming I am plugging the speakers into the digital output. Thanks for the help!
