I'm running Windows ME and have no sound. My computer will do this on occassion and I can usually shut down, or do a resotre and get the sound back. Last week I had great sound no problem, come home from a weekend trip, no sound at all. No one has been on the computer, the speakers are connected properly and yes they are plugged in, just no sound. I checked to see my volume settings and no, none are muted. Help.
