I had built a computer a few years ago, and my headphones have always worked fine with it. However, for the past view months, headphones - regardless of the pair - headphones don't work unless you play with the cable and have it sit in a specific position. I have no speakers connected to my PC so headphones are the only sound device connected, meaning that once the cable moves and they get disconnected, problems arise with certain programs and websites (discord, youtube, games, etc). One of my friends said that this issue is with my tower. What could be the cause of the issue?
