Windows 7 includes a handy Volume Mixer tool that lets you quickly access sound settings. To open the Volume Mixer, click the Start button, type “volume mixer” into the search box, and press Enter. The Volume Mixer appears on the right side of the screen. To change the sound volume, use the slider controls to adjust the volume level for each audio source. You can also use the buttons to play music or videos in silence, mute all sounds, or turn up the volume for a specific application. To exit the Volume Mixer, click anywhere outside of it or press Esc. ..
We should start off by pointing out that you can right-click the sound icon in the tray, and get a quick menu that gives you access to Sounds, Mixer, etc.
If you single-click on the volume icon, it’ll pop up the slider that we’re all familiar with—but you can also click the Speaker icon to open up the Speaker Properties dialog.
Not surprisingly, you can change your speaker settings in here.
If you open up the full mixer panel, you can also click on the System Sounds icon…
Which, naturally, pops up the Sounds panel where you can disable particular sounds, or all of them.
It’s nothing revolutionary, but Windows 7 is full of these little tiny tweaks that just make things easier to use.
