Trouble installing audio drivers on notebook

[gd]

Hello...

I recently repartitioned a friend's notebook HD in order to install XP and kubuntu (it came with vista)... However I haven't been able to install audio drivers for its audio devices..

The laptop is a toshiba Satellite A200-PSAE6E and everest reports the following audio controllers:

ati hd 2xxx hdmi @ ati radeon hd 2600 - high definition audio controller
realtek alc268 @ intel 82801hbm ich8m - high definition audio controller

First I tried downloading the high definition audio drivers from realtek's web site (windows xp 32-bit version). I tried running setup, manually browsing to the WDM folder during driver installation and manually browsing to the folders where the drivers were copied during setup under c:\windows\system32\... all to no avail...

Next I tried downloading the official toshiba drivers from toshiba europe's support web site for the realtek chip... i experienced the same behaviour (both when running setup and manually forcing installation of the drivers)

Next I tried downloading the drivers for ATI HDMI audio device from realtek's web site... with the same results....

Windows keeps telling me that it was unable to find a driver within any of the archives...

The only thing that could be the culprit as far as i can tell, is that i have installed service pack 3 RC2...

if anybody has any ideas it would be more than appreciated....

P.S. I have tried both automatic installation through specifying a folder and choosing the "i will manually select a driver from a list" options in the hardware installation wizard... the result is always the same.... Note that sound output works perfectly under ubuntu...

I have personally had terrible troubles getting my sound functional via HDMI on a 3870. Might want to try disabling the ATI audio device in the device manager and work on the Realtek. Their should be a driver specifically for the device you listed without anything referencing ATI.

When testing the audio also make sure you have the correct auio device selected under Control panel -> Sounds -> Audio tab. Even if you get one working you wont hear anything if the correct device isn't selected there.

Edit: I have no idea how the machine handles HDMI audio on a laptop. I assume unless you are trying to pipe the sound out to an external source you have no need for the audio drivers on the video card?
