Is Discord mic picking up all PC sounds including game audio, YouTube, or system alerts? The fix is switching your Windows recording device to your real microphone and disabling Stereo Mix. Go to Sound Settings → Input → Choose your default mic, then never select "Stereo Mix" or "What U Hear." For USB headsets, disable Hands‑Free AG Audio entirely, and turn off advanced Voice Isolation on iOS/macOS . 🎮🔇
