Sound not working at all after clean install of Windows 7

No yellow triangles, just 4 Nvidia HD audio and Realtek HD audio.

Yes I checked them all and rebooted, I'll try it again now though just to double check.

Okay I uninstalled them, nothing seems to of happened.
I also used Driver sweeper on Realtek again, rebooted, and Realtek is still there..

Sorry the driver sweeper deleted all the files except for one, it says "Realtek - Sound"

Should I uninstall Realtek manually, THEN use driver sweeper, THEN use the one you linked me earlier?

I downloaded it but haven't ran it yet, because Realtek was still there.

HD audio controller is Enabled, I also changed Front panel type to HD.

I also changed the sound type in the Audio manager to HD, it proceeded to say "You have unplugged an audio device" and disabled "Speakers" in playback devices.

When I change it back (In the audio manager, not bios) to AC97, speakers is enabled again.

There was a brief moment, when I changed it to HD, when it popped up for me to select the device I just plugged in, but it was there for literally 1 second and went away again..

Going to try the troubleshooter.

With all the driver and settings manipulations that have been done, I'm wondering if this piece of advice has been tried yet:

Sound not working at all after clean install of Windows 7

Specifically referring to the reference of trying a System Restore....

Audio troubleshooter didn't detect any problems.

I also checked System restore, the only restore points are from today..
