My current setup allowed me to have a "stereo mix" recording device back when i used windows XP, so I know its not a hardware issue. But it doesn't show up in the list of recording devices anymore.

I've already taken a look at the following resources:

* <http://www.howtogeek.com/howto/39532/how-to-enable-stereo-mix-in-windows-7-to-record-audio/> - this is helpful, but doesn't give me enough information. Showing disabled and disconnected devices doesn't work for me. The guide mentions you might have to downgrade your audio drivers, but doesn't explain how to do that.
* [Cannot find 'Stereo Mix' on Windows 7](https://superuser.com/questions/114571/cannot-find-stereo-mix-on-windows-7) - the answer isn't correct
* [Windows 7 stereomix](https://superuser.com/questions/634610/window-7-stereomix)
* [How can I get stereo mix for my Windows 7 computer?](https://superuser.com/questions/246927/how-can-i-get-stereo-mix-for-my-windows-7-computer)

* <http://forum.audacityteam.org/viewtopic.php?f=36&t=4826> - this is helpful, but I don't want to have to use a loop-back cable. I can, but that's not what this question's about.

So I've tried showing disabled and disconnected devices in the Sound -> Recording list. Doesn't work. So:

A. Are there any other methods (or programs) to help solve this problem (other than ones mentioned above ^)?

B. How should I go about downgrading my audio drivers, if that's the best method to take? What year, or version of drivers should I be looking for? Etc.

My specifics:

In Device Manager, under Sound, Video and game controllers, I see "High Devinition Audio Device" which has a driver from Microsoft dated 2010-11-19. I also see 4 instnaces of "NVIDIA High Definition Audio" all with drivers from NVIDIA dating 2013-06-16 (version 1.3.26.4).

Any ideas?
