Driver Installation Failed: Could not find Media device for this driver

I have a HP dv6646us with Windows Vista (32bit) and have had a problem with the sound device. The sound sometimes work, but mostly the system doesn't even recognize the sound output device (in this case, I see that the speaker icon on the task bar with a cross mark). Another pattern is that the laptop does recognize the sound device, but produces no sound (in this case, the speaker icon doesn't have the cross mark). When the system at least recognize the sound device, I can solve the problem by using the Microsoft Fix it 50131. However, when the system doesn't recognize the sound device, nothing seems to work. When I go to the device manager, there is no sound section, not just a driver. The laptop is supposed to use Conexant High-Definition Audio Driver, but when I try to install it, I get the following message: Driver Installation Failed: Could not find Media device for this driver.


In another forum, a person solved the same problem in a system with XP 32bit version by downgrading his memory from 4GB to 2GB based on his knowledge that a 32 bit system can't take 4GB of RAM (he started to have the problem after he first upgraded the RAM from 2GB to 4GB). However, I'm not sure if the same thing applies to my problem since the sound system does work sometimes with the current system with 4GB RAM and also my laptop is supposed to hold up to 4GB RAM (and it does recognize the 4GB RAM). So, I'm wondering if there is any other possibility for a cause and a solution for this problem.
