Did the same thing with my 8950, plug in then no sound even from speakers, have to go into sound settings and switch it manually
 i am just starting my computer up for the first time and i ran a benchmark to see what its capable of and as i run it i see it is using the onboard graphics driver instead of my RTX 3060 so i am going to watch a video on how to fix it and i need to connect my headphones (wired) to the computer and as i plug them in nothing happens so i try the slots on the rear of the PC and nothing works as it is not registering that anything is connected.
When connecting my headphones into any slots they don't connect? (XPS 8940 
desktop)
