As that is something the laptop maker added and not a stock feature of the OS, only the maker can fix, issue a patch or update to cure it.
This is not a big issue or anything, but something that bugs me. when ever i hit the volume button on my laptop, an icon would show the volume going up or down. It no longer is showing that volume bar. It is driving me nuts because I can't see how far the volume is going. please help me fix this minor problem. Thanks
