Hello, I have windows 10 64 bits, some older games, such as COD2, do not turn on when the computer lacks stereo mix. This is where my problem begins. In the sounds, despite enabling the option to show all devices, I still do not have a stereo mix. I tried installing drivers from realtek, updating the audio from nvidia, but it still did not have any effect and the stereo mix was not so, no further. Can anyone help it?
