Realtec troubles with headset

Im bad at PCs just to get it out of the way.

Basically i got a new pc and tried to instal a headset with a 3.5 jack. since realtek wanted me to classify it as either input or output (not both) i was unable to use it.

someone recommended uninstalling realtek and using an earlier versions. well now i have uninstalled and i when i install an older version it doesnt work. no i have even less chances of getting the headset to work.

can i say how fucking frustrating this is? why is this msi realtek software so fucking bad? i tried to work with it but it looks different on other peoples pc and on mine i cant change anything and it says my headset is a soundsystem.

what i need is a way to reinstal realtec since it seems to be the only possible driver.

and then a way to get it to accept that headsets exist.

sorry that i cant give more details, but i will look up anything in my system settings if you need info about my pc. i know basically only that it is MSI and that i am out of my depth.

thank you kindly in advance
