Did you check the device manager to see if there is a yellow question mark under Human Interface Devices? The HP Quicklaunch buttons should be listed there.

This problem is driving me crazy. The mute button on my HP dv6000 laptop will not unmute. The volume controls does not say that the sound is muted...but it most definitely is. I have tried to re-install the drivers for quickplay AND my sound card. I have tried to disable quickplay in the device manager, as someone else suggested on another forum. Please help me, I just bought a season of The Office and I just want to watch it!
