When in a multi-user steam chat room, is it possible to mute a specific person, ideally without blocking other communication from them? I'm playing in the same physical room as the person and I'd like us both to be able to chat without having to hear each other twice.
There is no way to mute a specific user in a Steam group call. Even blocking the user on Steam will not mute the user in the call. The only way to prevent hearing the user is to mute the whole call or leave it.
