Acer 8730 volume slider control does not work

[dks123]

Acer Aspire 8730
The Volume slider on the right side of the keyboard (media controls) doesn't work (never has). I can turn up the volume with the control in the system tray. Is there something I am missing? Acer tech support said I need to use my system disk and restore my hard drive back to factory settings. I would have to reload all my programs. Is there a way to avoid this and get the volume slider to work?

Thank you
