Discord (VoIP) never works for me. When I speak, people always tell me I sound like a guitar or a robot, or that my voice is really glitchy. I can hear them fine though. I have tried changing the server, rebooting the PC/Router/Modem, and making a rule for it to bypass my firewall, but nothing seems to work. This has been going on since I moved house 2 years ago. Please help.
