Problem Details:
Hello, since a year im playing osu and I never had troubles but today i tried to play and i realized that there is no sound at all (the other programs have sound, just osu doesnt) so i tried to turn the volume up from options but it was already up, then i went to the system mixer but it does not appear on it
. Also tried to play anyway but i cant hit any circles, i mean i can click the buttons like "skip" but when i click the circles the game counts as a miss and automatically lose. 
PS: I tried out to play with the click and with the keyboard keys.
Video or screenshot showing the problem:
osu! version: 20150414.2 (latest)
