SMARTEC  For this you can easily find SoundAsleep... you can set a range of time when all sounds should be off.

This is not a purpose of MacAutoMute as I say in macautomute.com

... and think about it.. you must remember to change settings if someday you need another time-range.

But if you need it, soundasleep is your choice
