No sound after windows XP installation REPLY

Hello! I got a virus on this computer, so I decided to reinstall windows and start fresh. After the installation I found out I have no sound, when I look at my output device, it says none selected, and I can't find any devices to use. When I look in Device manager, it says Legacy audio drivers and Audio Codecs. These are devices I never had previously installed. If you can find a solution, that would be greatly appreciated. Thank you for taking the time to read about my problem. Comments: Jun 08, 2009Okay thank you for the fast reply.
