My audio doesn't work.

[Warlord711]

So I've tried to fix my audio in several ways, most of them I found here on these forums. But so far none of them have worked. I try to install ANY sort of realtek or audio drivers and it gives me the "We cannot find the HD Audio device." error. When I go into my sound settings this:

is what I see.I tried uninstalling the NVIDIA Audio drivers and then these drivers appeared. I have no idea what is wrong or what to do anymore, so any help will be greatly appreciated.

My (Relevant) Specs:

OS: Windows 7 home premium 64 bit
Motherboard: Asus m5a78l-M/usb3
Graphics card: EVGA GeForce GTX 760 2GB

The reason that Realtek audio drivers don't work is that your motherboard does not have that chip. From the specs for that system: VIA VT1708S 8-Channel High Definition Audio CODEC

Get the drivers for the audio chip from ASUS https://www.asus.com/Motherboards/M5A78LMUSB3/#support

I have already tried downloading the audio driver from that website and it gives me the audio device cannot be found error.

Check the BIOS to make sure the onboard audio is enabled. You can also try a BIOS update if there is one available. If no update, reset the BIOS by pulling the CMOS battery or using the reset jumper.

Has the sound ever worked? When did it stop working?

Well I tried to do the most recent BIOS update from the asus site and it tells me it is a ROM File and that I don't have the right program to open it. Also, I am fairly computer illiterate so I don't really know how to do those things.
The audio hasn't worked at all (I built this computer about 5 days ago).

The first thing is if the integrated audio chip on the motherboard is right then you should be able to hear the audio. The first thing what you do is to remove all the installed hardware drivers from your system. Go to "Device manger" and expand "sounds" menu and you will be able to see the installed sound drivers. Remove whatever is there.
Now go to the motherboard manufacturer's website in your case it is Asus.
Go to this site https://www.asus.com/Motherboards/M5A78LMUSB3/#support
Select the operating system you have installed and then select audio and download the driver and install it. This should work fine.
Go to sound settings and as you have included the picture above if you see more than two playback devices (one should be headphone and one speaker) try disabling one by one and see which one works.
If you want to download the most matching driver for your audio hardware then you can use a utility software called "drivermax" free from http://www.drivermax.com

Did you install the other drivers for the system, especially the chipset?

No apparently 14 of my drivers are outdated. I've already download 4 of them but this porgram only lets me download 2 a day as a free user so I guess I'll need to wait a few more days and see if this fixes the problem

Hold on here, what "this program"? Don't use any third party drive finder stuff, get the drivers directly from the hardware endor.

Drivermax. And I downloaded the audio drivers from the asus site, the one for my motherboard and it didn't work.
