So sorry SirKenin, you misunderstood. The speakers work on the other PC and my headphones work in the ports on the front of the PC. I think they may be right about the ports in the back.
So do I replace the port?
lol. Hun, the same controller operates both ports. The front panel uses a header on the board, the back goes direct. There are software settings with Realtek controllers to disable the rear outputs, etc. Start going through the Realtek settings and find out where your problem is. It could also very easily be a driver issue. Uninstall the driver and let Windows redetect the device sometimes works. Also, try resetting your BIOS to defaults. With the Dells, some have that option, some you have to have the caps lock, num lock and scroll lock enabled, then press <CTRL> <ALT> <F>. It will beep to let you know it was done right.
A "port" on the back is really only a socket with contacts in them. Unless the contacts have somehow gone bad which would be so insanely rare that it has a better chance of being struck by a meteorite.. There's nothing to go wrong with the "port" itself. It's somewhat possible that a part went bad on the board, but before you have that moron getting you to ship your computer all over creation, there are other things to check.
I would suggest going through your settings with a magnifying glass. I would also suggest forgetting that PC eye even exists.. His reputation is to mislead and cost people a fortune in time, aggravation and money. Just look at his post history.
