I have a problem with my Line In port and I hope someone can help me. It's On Board on an HP PC. I have 2 of these computer and on one the Line In port works fine. I would plug the cable in and when I tab the other end or attach an audio source the Line In volume bar would go up and down. On my other PC it looks like this:
I only get that solid bar the moment a cable is plugged in, but there is no audio going through.
