When I upgraded my 8.0 application to 8.1 I lost my sound system on my computer.  I get a message each time I start up my computer that instructs me to reinstall my Dolby Audio Driver.  How do I do this?

Hey,

• Open Device Manager.
• Go to Sound, Video and Games Controllers section.
• Right Click on the Conexant Smart Audio HD item and then Uninstall it.

• Right-Click on it and choose update driver.
• Navigate to d:\drivers\audio.
• Once its done, close Device Manager.

Hope it will help you.
