UAA MYSTERY COMPAQ C765EM
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.

You installed Vista?
Was this an upgrade or repair? or reinstall?
Was it a clean install new partition?
you didnt get any mainboard discs with it?

ALWAYS go to the manufacturers site for drivers! You wouldn't believe how many messed up systems I see because folks used "driver genius" or some 3rd party utility.
NOBIS gave you the correct link and you need to install the BIOS, chipset, audio, video, and network drivers, then do nothing but Windows Update until it says there aren't any more.

Hi
Yes, that is the hp page where I downloaded all the drivers. All vista updates have been installed from .the microsoft update website. Pictures of Device Manager are here.

ok
since there are no unknown devices shown - nor an entry for modem or sound, i would check first in the bios if they are enabled

There is no option to turn off the audio chip in that BIOS; but, HP is listing the wrong driver for the audio! According to the specs ( http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01411631&tmp_task=prodinfoCategory&cc=uk&dlc=&lang=&lc=en&product=3716451 ), you have a 3D Sound Blaster Pro compatible sound 16 bit integrated and they are listing the Realtek driver (oops).

I did install this driver, and indeed the latest version too but no luck. The motherboard had a conexant audio chipset on it. Also the bios and all other drivers are the latest ones from hp website.
are they enabled in the bios as asked?
ASKER
There is no option in the bios for audio devices etc. It appears to be a very basic bios, even the latest version.
and modem? nothing ?
test if the sound works if booted from a live knoppix cd then - and test the modem too

This gets as far as Starting Hardware Detection And Configurtion (hwsetup)... and then it sits there doing nothing
I asked earlier if this was an upgrade a clean reinstall or a repair reinstall.
This would greatly assist.
So on that I'll offer these suggestions.
If you performed an upgrade from XP there was some updates required before hand, also the upgrade had to match your XP version as in XP professional SP2 to Vista Professional sp2
If in the upgrade path the bios was out of date or some drivers were out of date or you didnt / dont have sufficient ram the upgrade may have wrongly installed them or they were not compatible.
compaq have an OEM upgrade disc that includes all the onboard correct drivers for your Compaq laptop / desktop it is called
Express Upgrade kit
What is the HP Express Upgrade Kit and is it right for my PC?

Yes, I did these. Ant the sound video game controller tab is still not there.
what about my post? any comment?
Hmmm....
How much ram do you have in that laptop? 4GB is the limit on many chipsets and even that can cause a hardware conflict in that the top of the memory is used to map devices.
And, please post the P/N from the bottom of the unit. It almost always ends in #ABA.

Hi Nobus.
Sorry I forgot to reply to you. Yes I tried this too. In fact I stripped it down to the bones removed and removed the cmos battery too, just to be sure it was all clear, hopefully removing any bios glitch, but nothing working at the moment.

since knoppix did not run (test the cd on another PC to be sure it is OK) i must conclude you have bad hardware
if the rest works OK - you can try a separate sound card : http://www.nextag.com/laptop-sound-card/stores-html
