Try a few articles from this Google to see if you can show the volume control on the taskbar.
brandiejean here again.
Just recently, my voume shortcut(icon)has gone missing from my taskbar.
the shortcut was a picture of a yellow speaker--megaphone shaped, know what I mean?
I have the windows me system, on a compaq.
it's a pain to plug in and unplug the speakers, especially when you are used to being able to mute, or turn down the volume, by just hitting the shortcut.
hope someone can help, thanks.
