Hi, I'm new and I really don't know how common or uncommon this problem may be, so I hope you'll be patient with me. My computer isn't playing any sound at all, and it hasn't for two days. When I clicked on the little volume icon in the bottom right corner of the screen, nothing even popped up, and when I checked again the icon was gone altogether. When I go to the sounds area in Control Panel, absolutely everything is grayed out. How can I fix this??? Thank you very much, I look forward to some helpful hints.
