屏幕右下角的声音控制图标突然不见在控制面板打上钩了也没用，谁能告诉我怎么办，多谢
try this?
u can enter bios when open the pc and go to the "others" section.
there is a "System Beep" under that section, disable it and enable it again. then save the changes and restart.
my pc always like that :P whenever i install new software or do some changes, the sound disappears.
maybe this can work :D
