So my on-screen display for my volume control on my HP Pavilion dv5000 has stopped working. I can still use the quick launch buttons and change the volume, but the green volume meter no longer shows up on screen. I've tried downloading the quick launch button drivers from HP, along with doing a system restore, and neither worked. The online forums don't seem to be too much help... Any ideas? Anyone know what program is responsible for controlling the display?
