I often leave my PC often overnight and it has speakers attached. Sometimes I get notifications, emails, and instant messages during the night and it will wake others in the house up. I'd like to be able to set a quiet time where notifications either are suppressed (like the DnD in the system tray applet) or just muted so there's no audio.
Yeah I'd like this too. *** This bug has been marked as a duplicate of bug 412471 ***
