As the user said, it’s impossible, but you can set up a fake voice box for each player. Then, when you mute someone, move that new fake voice box to a null position or a position that no one can be near. This will make it so you cannot hear that player. I use this type of system for my Voicechat testing game to make it so you can listen to all players from any distance or only specific players. If you need any more help, don’t be shy and let me know!
