Realtek audio, no sound, need help!

I just installed Windows 7 on my Acer Aspire E380 desktop. I have tried downloading and installing newest drivers, and still am unable to get sound. I have tried uninstalling and reinstalling, still no sound. I have checked in device manager and everything says the driver is working properly. I have also checked to make sure I have the most up to date driver installed, and still no sound. I have a Realtek High Defininition Audio card that came installed factory on the computer.

And of course I have checked to make sure I have all wires hooked up correctly.

Please someone help!

The sound card is built in, and I have attached a screenshot.

Please fill in more of your system specs.

Hmm, have you tried changing the sound profile in your BIOS to AC'97?

No, how do I do this?

Have you downloaded the 8500 video graphics drivers directly from Nvidia?

Yes I have..and now the problem has changed entirely. Tried a set of headphones to the front jack and they work. And if I turn my computer speakers up to the highest amount possible, I can BARELY hear sound.
