I accidentally delete or lost the Speaker icon next to the clock at the bottom of my computer and cannot get any sounds from the computer whatsoever.please assist. Thank you.

Go to your Control Panel and then open "Hardware & Sounds" in Windows 7 or in Windows XP open "Sounds and Audio devices". In the "Volume" tab there is a check box "Place volume icon in task bar". Check it. If there is no check box right click on the volume icon there and create a shortcut.

In this case you have to look at the sound driver. Try to reinstall it.

You will want to go to control panel and go to sounds, if you go through the tabs (probably the first) there will be a check box that says 'show sound icon on system tray' enable this and whala.
