Chances are, it's just hidden. Right-click on that area annd choose the option that lets you display the 'Notification Icons', click on the Volume icon and set it to 'always show', it might be set to 'Hide when Inactive'.
thanks everyone. i have checked the 'realtek hf audio manager' - which i believe to be the sound so hopefully this will resolve. i am on vista. could not locate the volume tab or audio devices but hopefully the above will sort it. cheers
In Vista the volume icon can be turned on or off by right clicking on the taskbar and selecting properties then on the notification area tab check that volume is ticked. There is also a box to tick to hide inactive icons. You may want to untick this.
When this problem ocurs the Volume (sometimes it's the network icon, or power one) are missing from the options... they are greyed out... non selectable. Deleting and reseting the icon streams in the link above resets it all. Should have added that you need to do a restart after the this to let all new notification icons appear and then customise in the normal way.
