I am using HyperX Cloud 2. It comes with its own sound card/USB dongle. First Video: If I turn the mic sensitivity up a lot if does this. Every time it echo's my PC sounds the echo with get louder and louder to where it hearts your ears. Second Video: If I turn the mic sensitivity all the way down it does this. It plays all sounds from my PC and adds an echo to it. I have uninstalled every single sound driver and reinstalled them. I have reset my whole PC. I have disabled every Playback and Recording driver besides the headset. I have turned off effects for every Playback device. I uninstalled Realtek HD Audio Manager.
