Microphone not working after OS change

[vmacdermott]

I have an HP entertainment laptop that had Vista removed and XP installed. Now the mic won't work and although the webcam works it shows only the USB video device in device manager. There is no onboard webcam listed there. Any ideas?

It can be impossible to find drivers for laptops when downgrading to XP. It is always better to upgrade Vista to Windows 7.
