I had to wipe my hard drive and reinstall everything from scratch, and somehow I lost all audio except system sounds (like beep from errors). It appears that I do not have drivers installed for whatever sound cards / audio devices I have, because under Contol Panel, Sounds and Audio Devices, it says "no audio device".
The computer in question is a cheap refurb, and the only disk that came with it was a Windows XP disk - there is no disk of drivers.
