Individual clients can be locally muted. This information is handled client-side only and not visibile to other clients. It mainly serves as a sort of individual "ban" or "ignore" feature, where users can decide not to listen to certain clients anymore.

When a client becomes muted, he will no longer be heard by the muter. Also the TeamSpeak 3 server will stop sending voice packets.

The mute state is not visible to the muted client nor to other clients. It is only available to the muting client by checking the CLIENT_IS_MUTED client property.

To mute one or more clients:

To unmute one or more clients:

Returns ERROR_ok on success, otherwise an error code as defined in public_errors.h.

Example to mute two clients:

anyID clientIDArray[3];  // List of two clients plus terminating zero
clientIDArray[0] = 123;  // First client ID to mute
clientIDArray[1] = 456;  // Second client ID to mute
clientIDArray[2] = 0;    // Terminating zero

if(ts3client_requestMuteClients(scHandlerID, clientIDArray) != ERROR_ok)  /* Mute clients */
    printf("Error muting clients: %d\n", error);

To check if a client is currently muted, query the CLIENT_IS_MUTED client property:

int clientIsMuted;
if(ts3client_getClientVariableAsInt(scHandlerID, clientID, CLIENT_IS_MUTED, &clientIsMuted) != ERROR_ok)
    printf("Error querying client muted state\n);
