How to turn off notifications sounds when OS X is in Do Not Disturb mode? (High Sierra) Toggling "Do Not Disturb" blocks banners/alerts for notifications, but I still hear the sound when I, for example, get a message.

Is there any way to mute the Notification sounds without muting the entire computer?
Notification sounds are silenced in Do Not Disturb mode. Contacts marked with Emergency Bypass will bypass this and allow the notification sound to be played.
