Based on steps in a previous forum it appears my headphone jack is broken. The speakers work (based on other steps that I followed) so it appears my Dell desktop thinks the headphones are installed and mutes the speakers. In my travels through my computer when trying to solve this problem I could have sworn I saw a dropdown setting where both the speakers and headphones would play simultaneously. I figured I'd trigger that setting and get my speakers back but of course I can no longer find it. Is anyone familiar with that setting in XP Professional and where to find it?
