To change the Volume on my Laptop, i need to hit Fn-F9-F11 depending if i want to move it up/down or mute. But it will only change it if i deselct the programs I am using, As in Playing a game, i have to minize it, and click the taskbar, then im able to change the volume from those keys, rather than that it will not change it.
Does anyone know why it might do this?
