Computer Speakers wont work? no brand OR instaltion disc!?

Question

My computer had a virus, so my dad cleaned it up. When i had the virus, my speakers worked. That day, right after my computer was cleaned, they worked. Now, my computer is telling me I haven't got a audio device hooked up, so nothing will play. There is a D on the front of both speakers with an oval and a crescent surrounding the D. You can hear the fuzz, and see the light so i know my speakers are on and working. I am afraid i lost the installation disc. My dad would be REALLY mad if we had to by new speakers. Is there anything I can do?

Answer 1

I have a portable dvd player with that symbol and the Brand namee is Durabrand. Also, i accidentally deleted my speaker driver once and if you go to Windows update you can find it. It's called Sigma Tel. If you search for that you should find it.
