I lost the sound on my acer desktop when I down loaded a manual for my computer. it's an aspire
x3400g. I'm not computer literate but the on the computer seemed to get lost when I tried to
download the manual. What I would call an invading software called livid. The one thing I'm pretty
sure of is that is a small glitch that I'm not seeing. I tried playing music thru my windows music
player. The player worked but no sound.
