Missing sound recording option "Stereo Mix" / "Record What you hear" / "Waveout mix"

I had the same problem in Windows. I found the following solution:

1. Find the latest version of your driver, download it.
2. Uninstall your current driver and install the new one.
3. After uninstalling the driver and rebooting it will be automatically reinstalled. The audio still may not work.
4. Amazingly though, sometimes after putting the system in hibernate mode and coming back, the audio worked.

Hope it helps if it doesn't they have other suggestions.

Solved the problem by purchasing the external sound card - Creative Sound Blaster X-Fi Surround 5.1 Pro USB Audio System with SBX SB1095

There is a new Windows 10 Universal App(free) called WhatUHear.
Record off any loopback device. No messing with settings.
