Currently, there isn't a direct method to mute all participants in a room at once. However, you can mute individual participants' tracks using the RoomService API's

MutePublishedTrack

method. Here's an example of how you can mute a specific participant's track:

roomClient.MutePublishedTrack(context.Background(), &livekit.MuteRoomTrackRequest{
    Room:     roomName,
    Identity: identity,
    TrackSid: "track_sid",
    Muted:    true,
})

To mute all participants, you would need to: • List all participants in the room • Iterate through each participant and their tracks • Call

MutePublishedTrack

for each track you want to mute Let me know if you need further assistance! Sources: lksdk package - github.com/livekit/server-sdk-go/v2 - Go Packages | lksdk package - github.com/livekit/server-sdk-go/v2 - Go Packages
