I am getting an audio distortion that makes the game sounds play at very low bit rate its fuzzy with a faint echo. I have tried using the command KillAllSounds with no luck. It happens randomly on any map and I am unsure if a merc is causing it. Only once has it gone away on its own during a round every other time I had to reset the client.
