Audio Settings

I think a single master slider that controls all other audio slider settings would be very helpful for when you want to mute everything and then turn it back on. This would be useful for those who have all their audio settings at 100. Maybe an on/off button would work better so that you can turn off all sound and when it is turned on it reverts all sound settings to the previous settings before the sound was turned off. For example, off would be no sound while on would be 100, 67, 54, etc. for different sound settings the player has already set.
