Setting volume levels for applications on Windows 7
Adjusting the volume levels based on time can prevent disturbances from applications and the like.
Sometimes programs come loaded with all sorts of sound notifications and little to no way of adjusting the volumes. Even worse is when some of the sounds are, for one reason or another, ignored by the volume control the program offers. Using these simple steps you can adjust the overall volumes of certain programs without having to mess with the master volume of your system.
Step 1: Locate and right click on the volume control icon in your Windows system tray (the collection of icons to the right side of the taskbar).
Step 2: Select Open Volume Mixer from the list that appears.
From the window that appears you can adjust the volumes of any application currently open on your computer.
Step 3: Find the application whose sounds are offending your ears in the list and adjust its associated slider to a more reasonable volume.
Your changes should take immediate effect on any application's volume that is adjusted. If the application is being stubborn, just restart it.
