No audio device

I see many posts, but none that have addressed my problem.

A clients computer (HP Pavilion a320n - XP Home SP2) shows no sound device
in Sounds and Audio Devices Properties. I have:

Installed the correct drivers for the on-board sound (mobo: ASUS A7N8X-LA )
Checked that there are no conflicts in device manager
Ensured that on-board audio is enabled in the BIOS
Ensured Windows Audio Service is running
Run full anti virus scans (AVG & Norton), Spybot and Adaware

Curiously, the audio tab of Properties shows the nVidia nForce Audio Codec
Interface for the recording device but "no playback device". In safe mode,
the audio tab shows "no recording device" and "no playback device".

This is as far as I am able to go at this point. Not that these have
anything to do with the problem, but Norton live update will not connect to
it's server and errors out. Windows update will not connect to the Microsoft
site so I cannot update Windows. Otherwise, I have a good internet
connections. Safe mode with networking does not have networking for reasons
unknown at this point. I have been at this for hours. Please help and thanks
in advance.
