I have a Dell desktop that works perfectly fine except for the headphone jack. I've seen many complaints and solutions, but none fixing my problem. Common related problems include the speaker working, but when the plug in the headphones, no sound comes out. My situation is different. Yes, the speakers are fine, but when I plug in my headphones, Sound comes out of the system, not headphones. Please, if you have any suggestions, tell me even if you're not an expert.
