The Crymod Modding Portal offers a temporary fix for the looping sound bug that can be encountered in multiplayer Crysis games. The fix involves using console commands to shut down and restart sound in the game when the bug strikes, which is a kludgy, if effective, way to address this issue until it is patched. They also offer a slightly more elegant way to implement the same fix by binding the appropriate commands so the looping sound can be fixed with a keypress.
