Dopo una reinstallazione di xp pro. non si sente piu l'audio,precisamente mancano i driver per"AUDIO DEVICE ON HIGH DEFINITION AUDIO BUS".Ho provato di tutto: driver audio ati
driver realtek
scaricato hotfix di microsoft(kb 835221),ma niente .
A proposito dell'hotfix non ho ben capito come si installa:allego istruzioni in inglese

These instructions assume that you preinstall the relevant Windows OS over
a network, by using Windows PE.

1. Copy KB835221.exe or KB835221_srv03.exe to a subdirectory on your
technician computer.

For example, create a folder under the OPKTools directory called
Updates. Place the file KB835221.exe or KB835221_srv03.exe in the
Updates folder.

2. In Setup Manager create or modify an existing Windows
configuration set.

3. Add the following command-line information to the Preinstalled
Applications page in Setup Manager:

Executable: \\server\OpkTools\Updates\KB835221.exe (or KB835221_srv03.exe)

Parameters: -q -n -z

4. Save the configuration set.

5. Start the destination computer by using Windows PE and preinstall
the relevant Windows OS by using the command factory -winpe.

The UAA HD Audio OOB package is installed immediately after the Windows OS is
installed, and it will be enabled on the next reboot of the computer.
Se qualcuno potesse spiegarmi come si installano,oppure come faccio a risolvere questo errore di periferica.
grazie.
