Having installed vista on my compaq765em the sound and modem are no longer being detected. The microsoft uaa bus is not listed in device manager under system devices, the section for Sound Video And Game Controllers is absent from the device manager. If i try to install the conexant drivers from the hp website , it fails telling me that there are no devices for the drivers (audio or modem). I have checked for hidden devices but none are listed and there is only one called keyboard filter ???. I could not find a driver on the conexant website, and oddly ,the hp website says goto the Realtek website and download the latest HD AUDIO DRIVERS. I did this and installed it, but it didnt make any difference. I then downloaded various softpaq fixes of the WINXP uaa driver, installed these but still no joy. I do see the drivers listed in the filestore, hdaudbus.sys.
I have tryed to enable the hdaudbus service but it tells me it is either disabled or has no devices associated with it.
