Stereo Mix is missing – What can I do?

To fix this problem, you can try to update your audio chipset driver. With sound chipsets from Realtek, it should usually work. In other instances, however, it’s because the newest Windows drivers for your chipset don’t support this feature.

In order to fix this, you should try downloading and installing drivers from older Windows versions for your audio chipset. As always, before doing so make sure you create a backup of your system.
