So I just built my gaming pc. It is great except for one thing, the audio is messed up. Whenever I plug in headphones to my case, they are recognized but have a horrible lag/scratchy sound. It sounds like when you plug in headphones like half way. I did notice when building that the Hd audio cord coming from the case was very loose and would fall off of the motherboard often. Do any of you have this problem? How can I fix this?
