Vista Volume Mixer adds per program volume control
Previous versions of Windows let you set the volume levels only for inputs (such as microphones) and outputs (such as speakers and headphones). The new Volume Mixer in Windows Vista lets you set volume levels for each program. While some programs offer the ability to control the program’s volume inside the program’s interface, some don’t. The new Volume Mixer makes it easier to control volume for every program in a single place.

The Volume Mixer shows the currently-running programs that make sound (a program shows up on the mixer the first time the program makes a sound). Simply adjust the volume for each program how you want it. And once you set the volume for a program, Windows remembers the setting.
To get the Volume Mixer, just click the speaker icon in the Notification Area (where the clock is) and then click Mixer at the bottom of the volume slider. Or, just hit Start and type sndvol in the Search box.
