sudden loss of audio

[Guest]

All of a sudden my audio failed, and my computer reports that it cannot
detect an audio device. This happened in the past, and I corrected the
problem by using system restore - that doesn't seem to work this time.
Unlike previous times, this happened in the middle of a session and not after
starting up my computer. I checked the wires - everything is plugged in, the
volume is up, so I frankly don't know what the problem is. Any suggestions?

Where was this reported? Device Manager? If not, try removing the sound
driver and reinstalling it.

Go to Start/Run, and type DEVMGMT.MSC , highlight all sound devices, Action
menu, "Uninstall", then restart Windows, to find the device drivers again
automatically.
