In this video I walk you through how to use the console to mute the enemy team in Counter-Strike: Global Offensive. You can also use this method in any other multiplayer Source powered games.
Step 1: Open the developer console
Step 2: Type into the developer console 'cl_mute_enemy_team 1'
Step 3: The enemy team should now be muted. To re-enable enemy voice chat, type 'cl_mute_enemy_team 0' into the developer console.
