Muting or disabling voice
UOnsetVoipTalker has a few different ways to stop voice, depending on who should be affected.
Use SetMuted when one local player does not want to hear another player. Use the server-side mute functions when the server should control who can hear whom. Use SetVoipEnabled(false) only when a talker should be disabled completely.
Local mute
SetMuted is a client-side playback mute. Call it on the client of the player who wants to mute the audio.
For example, if Player A wants to mute Player B, call SetMuted(true) on Player B's UOnsetVoipTalker on Player A's client.
This only affects Player A. Other players can still hear Player B.
Call SetMuted(false) to unmute again. Use IsMuted to check the current local mute state.
On a listen server, SetMuted only affects what the host player hears. It does not stop the server from routing that talker's voice to other clients.
Server mute
Use SetMutedForPlayerState or SetMutedForVoipTalker when the server should stop one listener from hearing one specific speaker.
Call the function on the speaker's UOnsetVoipTalker, then pass the listener. This blocks that speaker's voice from being routed to that listener.
This is useful for block lists, moderation, team rules, or gameplay rules where the server controls voice access.
Use IsMutedForPlayerState or IsMutedForVoipTalker on the speaker talker to check the current state.
Channel mute
Use SetMutedOnVoiceChannel on the server when a talker should stay in a voice channel but should not be allowed to speak in it.
The talker can still listen to the channel if they are still in it. Channel mute only blocks that talker's outgoing voice on that channel.
Channel 0 is the world, proximity, and speaker component channel. Muting a talker on channel 0 prevents their proximity voice and speaker component voice from being routed.
Use IsMutedOnVoiceChannel to check the current channel mute state.
Disabling voice completely
Use SetVoipEnabled(false) on the server when a talker should not send voice to anyone.
This is stronger than muting one listener or one channel. For normal player mute menus, prefer SetMuted.
Calling SetVoipEnabled(false) on a client stops that client from playing and processing the talker's audio, but it does not replace the server-side mute functions.
