Realtek Jack Detetion And No Sound

I'm getting no sound out of my speakers(2.1), when I plug them into the green jack on the rear panel it says that I have plugged in the pink and black jacks, but neither of those are plugged in. I've spent hours on the phone with HP and looking on the internet but i can't find any solutions. I've updated every possible driver. Every now and then I can somehow get sound by messing with settings and restarting or doing a power drain or a million other things, but as soon as I restart the computer they aren't working again, and the same solution never seems to work twice. Also, when the sound does work, it still says the black and pink are plugged in.
