I see that a lot of people have the same problem I have they just have different computer's than I do. I have tried everything I know. I've cleared my hard drive twice and reinstalled my OS twice and my speakers still give no sound. I know that they aren't broken because I have tested them on My Ipod and they work fine. I'm not sure what to do and I'm not sure where to get the driver that I need. If anyone can help me I would be amazingly grateful. I use an emachines T2042 with windows XP.

You should be able to get drivers from the eMachines website. (http://www.emachines.com/support/product_support.html?cat=Desktops&subcat=T-Series&model=T2042)
