Visit the manufacturer's website to download, then install an updated audio driver.. It may or may not help, depending on whether the sound card is still functional..
Hope this helps.
Recently, I've discovered I can't adjust the volume on my computer, as in the volume when I have my headphones on. There's no volume icon in the corner and when I go to control panel/sounds,speech,audio devices/adjust system volume, the volume is turned all the way up.. when I try to click the 'Advanced...' section it says "Windows cannot display the volume control on the taskbar because the Volume Control program has not been installed. To install it, use Add/Remove Programs in Control Panel'. I do that, and can't find anything.. Does anyone have any ideas? Could it have somehow randomly been removed from my computer? If so, how can I get it back!?!?
