Latitude C640 -- C Dock/II Audio problem ScoutDoc

  Although the internal audio output from my notebook works fine (docked or undocked), I can't seem to get the audio output from the C/Dock II to work. When I initially purchased my notebook, my network administrators insisted on taking Windows XP off, and installing Windows 2000. XP was later installed when the network started supporting it. I know the C/Dock audio worked fine under Win 2000. I think it stopped working when XP was re-installed. I had originally thought this was a hardware problem, but I recently noticed a Knowledge Base article regarding Latitude C600 and C800 portables (Document TT1061041). It addressed this exact problem (loss of C/Dock II audio functionality with upgrading to WinXP), and recommended upgrading the audio driver from the Upgrade Drivers and Utilities CD. Unfortunately, I don't have an Upgrade Drivers and Utilities CD, only a Drivers and Utilities CD that came with the computer that is only for reinstalling drivers, not upgrading them. When I go to upgrade the driver from this CD, it does not offer me the choice recommended in the Knowledge Base article (ESS Maestro 3i (Audio Only)/M3WUA09A). It only offers me a Crystal driver.

Is there a driver that will help me with this problem? If so, how can I find it? Any other suggestions?

Thank you for the help. 10-24-2005 03:29 PM

Thanks so much for responding.

I'm a bit of a novice. What do you mean by the A02 version? I'm sure it refers to a driver, but I want to be sure I download and install the right one.
