Problem with Sound Driver

Okay well this is more or less trying to get my pink microphone jack...microphone working on my computer.
While it should show up. it doesn't it does NOT come up under disabled it IS plugged in.
I tried installing chipset drivers didn't help
i TRIED installing sound drivers *which i know is what i need* "Setup is unable to detect a supported product on your system. Please ensure that your product is properly installed before running this Setup program.
Setup will exit" i get this however.
I am using a XPS 420 and upgraded to windows 8.1 awhile ago.
I've been trying to find help on google and such and there was not much luck.

Dell does not support Win 7/8/8.1 on this system. You will likely need to install a PCI Windows 8.1 compatible sound card or a USB connected Win 8.1 compatible sound card. The latest OS that Dell supports is Vista and the Vista drivers are incompatible with Windows 8.1.
The Dell hardware is mostly proprietary in this model, thus I doubt you will find any useable Sigmatel sound drivers.

I used to work the Dell forums and users upgrading older systems to new OS' had to install sound cards on many models as Dell drivers were not available.
