Recently i purchased grimefighter, and was happy i could clean up my computer and get it to run at peak performance again. took an hour or so to get it all done. everything has worked up till now, but something was missing, and i don't know how to get it back. when i use the volume controls (FN) f7- it mutes it, without the default notification sowing up on screen. f8- it reduces my volume by 1 instead of by 10, without notification on my screen. f9-increases my volume by 1 instead of by 10, without notification on the screen. This issue happened after grimefighter was ran, and i would like those notifications restored, and increase my volume by increments of 10, not by 1, its uses no third party program to achieve this, just the primary factory sound driver. i have a alienware audio device, and a Realtek High Definition Audio, default device.
