Headphone Jacks, Webcam

Hello. I recently got my laptop computer upgraded to Windows Vista and all of
a sudden, a few of the devices that are integrated into the computer are not
working.

First, the headphone jacks on the front of the computer do not seem to be
working at all. Despite the fact that headphones or speakers (which work fine
when connected to other computers) are in the jacks, no sound travels through
the headphones/speakers and all of the sound still goes through the
integrated speakers.

Second, my integrated webcam is not being picked up by the Camera and
Scanner wizard or Windows Live Messenger, Nor is the integrated webcam.

Does anyone know how I might get these devices to work? The system is an HP
Pavillion 9005ca with 32-bit Vista Home Premium (Upgraded from Windows Media
Center XP)

Thanks in Advance for any advice you may be ale to give me.
