"Sound, video and game controllers" missing from Device Manager

[amanguver]

Hello. 

I installed Windows 7 64 bit on my laptop and I have installed all the drivers except the Audio. I can't find Sound Video and game controllers in the Device Manager. Even if I click show hidden devices it won't show it.

I have read that this notebook uses the Conexant High Definiton Audio driver and I have tried installing it with no success: The installer fails because it can't find the device for the driver.  I have also tried the Sound trobleshooter but it says it can't detect hardware changes. When I hover the mouse over the speaker icon it says "No audio output devices found"

I have installed several programs to detect and install missing drivers but they can't find the audio driver.

HP Driver support webpage for this model (https://support.hp.com/es-es/drivers/selfservice/hp-pavilion-dv6700-entertainment-notebook-pc-series...) only lists Windows Vista, but even if try to see the drivers available it gets stuck in a loading screen. I tried opening the same webpage on another PC with the same results.

I hope someone can help me fix this issue. Thanks in advance.

Hi:

Did the sound work right before you upgraded to W7?

The reason I ask is because those PC's with the nVidia chipsets are notorious for overheating and several components quit working.  They just disappear from the device manager.

Audio, wifi and DVD drive are the most common devices to fail.

The audio device would show up in the device manager as a multimedia audio controller if there was a driver that needed to be installed.

Since I do not see that device showing up in the device manager, I would have to assume the audio chip has failed.
