Sound not working at all after clean install of Windows 7

Maybe some dumb questions or i might have missed this info, but

Have you tried normal PC speakers using the BACK panel audio outputs?
Is this a custom build or a Pre-Built PC (HP, Dell, Lenovo, etc.) ?
If it's a custom build, who built it, installed OS, and configured it?

Do you have a TV or Monitor with built in speakers you could try using an HDMI connection?

Are you capable and willing to try hardware changes?

From what i see, i think you could remove the Nvidia GPU and use built in Video.
That could eliminate any Nvidia/Onboard Realtek audio conflict.

Ahh, so when I installed Realtek, it might of replaces a driver installed by windows?

Is this your reply to my questions in Post #71
, or are you asking someone else about a different previous Post ?

I tried using the speakers that are built into my monitor, still not working
I'm willing to do hardware changes.
I'm going to try the clean install first, just to rule out software completely.

In this tutorial :
Clean Reinstall - Factory OEM Windows 7

Do I just put the CD in and run the installer, or do I have to set the CD to boot first in the bios?

Set the CD to boot first in the bios, and have the CD (Windows installer) run on boot up.

Okay so I installed windows again, and my sound still refuses to work
Is it 100% down to hardware then?

What sound driver did the installer give you?

Is there a newer one offered via optional Windows Updates?

If you want to install TeamViewer with all defaults used during install, then PM me back the ID and password, I will connect but need you to be there to see if sound starts working.

I downloaded the Nvidia drivers and de-selected the Nvidia HD audio, but I could roll it back if it could cause problems.
Will you be available to do Teamviewer later on?

Did you run for awhile with only the drivers given by the installer and optional Windows Updates to know if they worked first, before installing the factory drivers?

This was the point of the passage in the tutorial which I quoted for you.

Yes, I could connect later but I cannot hear if your sound starts working.
