PS: I've also clicked on Customize Notification Icons and the Volume
icon is missing under both Current and Past Icons, so I can't activate
it from there. I've also checked the Task Bar & Start Menu Properties,
only to find that Volume is greyed out. I don't know if that will help
someone identify the problem or not. I know I can probably do a system
restore, but I'd like to know why this is happening, if possible. Thanks
to anyone who can provide some insight.

This continues to happen to me. I'm using Vista Home Premium. If you
right click in the notification areaProperties, you will see check
boxes - one of which is for the sound icon. On my PC, all four boxes
were greyed out. No problems in Device manager. While rebooting, I
notices that my sound icon (lit up on my keyboard) was red (meaning it
was shut off). I pressed it until it showed white - and my sound
returned. However, this doesn't explain why my other three boxes were
greyed out (clock, network and power). There's still a problem
somewhere. Until we figure it out (or someone else does), try
rebooting.
