IU have rebuilt a TC4400 tablet PC with XP PRo SP2. I have everything working well with exception to the Audio. I downloaded and tried to install the drivers, but receive an error "The HDA Audio bus driver is required and not found. I go back to the HP website and download the HDA bus driver. I run that install and get yet another error message which says "An error {-5011 : 0x80040707} has occured while running the setup.
If I go to device manager I can see 3 other devices listed with yellow question marks - 1 PCI device and 2 Unknown devices. I tried to update driver automatically on the PCI device, but that too failed. It reported that it could not find a device.
Any ideas how to get my audio back on this machine?
