My mx6920 gateway upgraded to windows 7 now headphone works but no delegation cannot find the audio device

I recently updated my mx6920 gateway for windows 7 and now, for some reason any laptop speakers will not work. The headphone jack works though. I tried to install the Audio drivers high definition on the RealTek site and was unsuccessful because windows has taught me that the driver is not the right one for the type of windows. Even when using the compatibility feature, does the same thing that I tried to use the Sigmatel drivers from the site of the bridge. These drivers ended up with the same problem. I checked Device Manager and it indicates that the audio device works. Who should ask me why do I hear audio from the headphone jack, but not the laptop speakers.

any help you could give me would be greatly appreciated

Thank you
