I just updated the Windows Vista in my Toshiba Satellite Laptop and it installed "Windows Search 4.0" programme in my laptop. After restarting to complete the installation, my audio output device was no more functioning, with an error message 'No audio device is installed'. Please what do I do?

sounds like a need for new drivers, check for vista drivers on the audio device's manufacturers website
