Microsoft Sound Mapper is no longer listed as an audio device in the
Windows (XP) Sounds setup or as an audio device in Audacity or Sound
Forge that I have installed. There's signs of life - the meters move but
nothing comes out the speakers or headphone jack.

I can select Realtek (the built-in sounc card) as the audio device, and
that used to work fine, but it doesn't now. I don't have any other audio
devices (like a USB audio I/O) that I can plug in to try.

Could I have lost the Realtek/Microsoft driver?

At the risk of being presumptuous, two avenues:

Rt Click My Computer, Manage, Device Manager - Sound, Video and Game
Controllers -
check for drivers missing or update as needed

Start, Control Panel, Sounds and Audio Devices - all of the controls for
your sound system -
check for something muted by chance
