hi. i have a xonar dx sound card, along with a 8ft extension cord which is plugged into the main audio output slot for both speakers and headphones. i have a 2.1 speaker setup, and was wondering if there was any way around having to always plug the speakers out to put in the headphones into the cord and reverse. simply put, is there a way to have both the speakers and the headphones plugged in at the same time and just choosing which one you want sending out sound, without audio quality loss? thanks
