Streamer Mode is such a useful tool that is incorporated into Discord. It allows the streamer to ensure that their streams will not be disturbed by things such as private messages and invitations while they are streaming. These things can seriously hinder you if you are streaming.
As Streamer Mode does block things such as popups, you may be wondering whether it mutes Discord completely. While it will not mute you while you are streaming, it does mute all client and Discord sounds which is particularly useful.
This means that you will not have to worry about sounds from messages you receive in the channel. It will enable you to disable the sounds and notification so that your  Stream will not be interrupted.
